Peacock goby (Tateurndina ocellicauda) merupakan salah satu ikan hias yang mendiami perairan gambut di wilayah Papua hingga bagian Timur Papua New Guinea. Data dan informasi mengenai aspek biologi ikan peacock goby untuk mendukung kegiatan budidaya masih terbatas. Penelitian bertujuan untuk mengkaji aspek pemijahan, perkembangan embrio dan larva ikan peacock goby. Induk ikan yang digunakan yaitu sembilan ekor induk jantan (bobot tubuh 0,69 ± 0,08 g) dan enam ekor induk betina (bobot tubuh 0,65 ± 0,03 g) dipelihara dalam wadah plastik berukuran 20 cm x 25 cm x 15 cm. Perbandingan induk jantan dan betina yaitu 1:1 (perlakuan A) dan 2:1 (perlakuan B), dengan ulangan sebanyak tiga kali. Wadah pemijahan dilengkapi dengan potongan pipa PVC berbentuk setengah lingkaran sebagai tempat menempelnya telur. Telur diinkubasi pada wadah penetasan berbeda, yaitu water bath (30°C-31°C) dan non-water bath (26°C-30°C). Hasil penelitian menunjukkan perbedaan rasio jantan dan betina tidak memengaruhi banyaknya jumlah pasangan induk yang memijah. Jumlah rata-rata telur pada perlakuan A (133,5 ± 41,72 butir) lebih banyak dibanding perlakuan B (108 ± 24,04 butir). Inkubasi telur menggunakan water bath menghasilkan jumlah telur yang menetas 215% lebih tinggi dibandingkan inkubasi non-water bath. Embrio ikan peacock goby mulai menetas pada hari kelima dan berakhir pada hari ketujuh setelah pemijahan, dan mencapai fase benih pada umur 33 hari setelah menetas. Survival activity index larva ikan peacock goby diperoleh nilai sebesar 10,6-35,45.Peacock goby (Tateurndina ocellicauda) is one of the ornamental fish inhabited peat waters stretched from the Papua region to the eastern part of Papua New Guinea. Despite its increasing exploitation and population pressure, there are currently limited studies and information regarding the biological aspects of the peacock goby fish. The research objective was to determine the spawning, embryogenesis, and larval ontogeny characteristics of the peacock goby in cultured setting. Nine of mature male broodstock (body weight 0.69 ± 0.08 g) and six of mature female broodstock (body weight 0.65 ± 0.03 g) resulted from gonad selection were reared in a plastic container measuring 20 cm x 25 cm x 15 cm in size. The ratios of male and female fish were 1:1 (treatment A) and 2:1 (treatment B), with three replications. The spawning container was equipped with a semicircular piece of PVC pipe for eggs shelter. The fertilized eggs were incubated in two hatching containers fitted with a water bath (30°C-31°C) and without a water bath (26°C-30°C). The results showed that the difference in the ratio of males and females did not affect the number of broodstock pairs to spawn. The average number of eggs in treatment A (133.5 ± 41.72 eggs) was higher than treatment B (108 ± 24.04 eggs). Egg incubation using water bath resulted in a higher number of hatched eggs by 215% than that of without a water bath. Peacock goby fish embryos began to hatch on the fifth day and ended on the seventh day. The larvae reached the juvenile phase at 33 days after hatching. Survival activity index (SAI) of peacock goby fish larvae were between 10.6-35.45.

Terbatasnya ketersediaan benih hingga saat ini masih menjadi kendala keberhasilan produksi ikan gurami. Hal ini salah satunya disebabkan oleh terjadinya infeksi jamur Saprolegnia sp. pada telur sehingga terjadi kegagalan dalam penetasan. Tujuan dari penelitian ini adalah untuk mengetahui efektivitas pemberian ekstrak daun eceng gondok dengan konsentrasi yang berbeda terhadap prevalensi dan pertumbuhan jamur Saprolegnia sp. pada telur gurami. Metode yang digunakan adalah eksperimen dengan rancangan acak lengkap (RAL). Ekstrak daun eceng gondok didapatkan melalui metode maserasi yaitu dengan perendaman serbuk daun eceng gondok dan ethanol 96% kemudian penguapan menggunakan rotary evaporator. Pengujian dilakukan dengan empat perlakuan dan lima ulangan. Wadah pemeliharaan menggunakan akuarium ukuran 15 cm x 15 cm x 20 cm. Interval pengamatan uji minimum inhibitory concentration (MIC), uji daya hambat, dan prevalensi masing-masing 48 jam, 5-7 hari, dan 24 jam. Dosis pengenceran ekstrak daun eceng gondok pada uji MIC yaitu 6,25%; 12,5%; 25%; dan 50%. Hasil penelitian dari MIC yaitu pada pengenceran 25% terjadi penghambatan pertumbuhan Saprolegnia sp. Kemudian dilakukan pengujian lanjutan yaitu uji daya hambat pengenceran terendah 6,5% dengan rentang pengenceran 0,25%. Hasil uji daya hambat masing-masing perlakuan A (0%) 0 mm, perlakuan B (6,5%) 1,44 mm; perlakuan C (6,75%) 1,92 mm; dan perlakuan D (7%) 2,26 mm. Dengan prevalensi masing-masing 46,8%; 28%; 22%; dan 17,6%. Kesimpulan dari penelitian ini adalah pada uji MIC hasil pengenceran 6,25% hingga 50% terjadi penghambatan pertumbuhan Saprolegnia sp. Uji lanjut daya hambat dari ekstrak daun eceng gondok secara keseluruhan memiliki tingkat daya hambat yang rendah yaitu £ 5 mm, namun semakin tinggi dosis yang digunakan dapat menurunkan tingkat prevalensi jamur Saprolegnia sp. pada telur gurami.Limited availability of seeds to date is still an obstacle to the success of gouramy production. This is partly due to the onsling of Saprolegnia sp. fungal infection on the egg so that there is a failure in hatching. The purpose of this study is to find out the effectiveness of giving hyacinth leaf extract with different concentrations against the prevalence and growth of Saprolegnia sp. on gouramy’s eggs. The method used was an experiment with RAL (Complete Randomized Design). The water hyacinth leaf extract is obtained through maceration method by soaking water hyacinth leaf powder and ethanol 96% then evaporation using a rotary evaporator. The test was carried out with 4 treatments and 5 replications. The maintenance container uses an aquarium 15 cm x 15 cm x 20 cm. Observation intervals of MIC test (minimum inhibitory concentration), inhibitory test, and the prevalence of 48 hours, 5-7 days, and 24 hours, respectively. Dilution doses of water hyacinth leaf extract in MIC test were 6.25%; 12.5%; 25%; and 50%. The results of research from MIC that is 25% dilution occurs inhibition of Saprolegnia sp. growth. Then, further testing is done with the lowest dilution inhibition test of 6.5% with a dilution range of 0.25%. The inhibitory test results for each treatment A (0%) 0 mm, treatment B (6.5%) 1.44 mm, treatment C (6.75%) 1.92 mm, and treatment D (7%) 2, 26 mm. With a prevalence of 46.8%, 28%, 22%, and 17.6%, respectively. The conclusion of this study is the MIC test results of dilution of 6.25% to 50% inhibition of growth of Saprolegnia sp. Further tests of inhibition of water hyacinth leaf extract as a whole have a low inhibitory level which is £ 5 mm, but the higher the dose used can reduce the prevalence rate.

Ikan cupang alam (Betta imbellis Ladiges, 1975) merupakan salah satu jenis ikan cupang asli Indonesia yang belum banyak dibudidayakan. Dalam pengembangan budidayanya, kemampuan reproduksi antar generasi masih perlu dikaji lebih mendalam. Penelitian ini bertujuan untuk menguji keragaan reproduksi tiga generasi ikan cupang alam. Perlakuan berupa induk generasi awal hasil tangkapan dari alam (G-0), generasi pertama (G-1), dan generasi kedua (G-2). Setiap generasi menggunakan tiga pasang induk, dan setiap pasang berlaku sebagai ulangan. Pemijahan secara alami menggunakan wadah baskom berdiameter 40 cm yang dilengkapi dengan shelter penempel telur. Pengamatan meliputi fekunditas, diameter telur, derajat pembuahan, dan derajat penetasan. Hasil penelitian menunjukkan bahwa perlakuan generasi tidak berpengaruh terhadap parameter diameter telur fekunditas dan derajat pembuahan (P>0,05). Namun berbeda nyata (P<0,05) dalam daya tetas antara generasi hasil domestikasi (G-1 dan G-2) dengan generasi awal (G-0).The wild-type fighting fish (Betta imbellis Ladiges, 1975) is a native species of Indonesia that has not been widely cultivated. In order to cultivate this species, the reproductive performance between generations of the fish needs to be studied. This study aimed to examine the reproductive performance of three generations of wild-type Betta imbellis. The treatments consisted of differently sourced broodstocks, i.e., caught from the wild (G-0), first produced generation (G-1), and second produced generation (G-2). Each broodstock group used three pairs of parents, where each pair acted as the replicates. The broodstock groups were naturally spawned in 40 cm diameter basins equipped with an egg-holding shelter. The observed parameters included fecundity, egg diameter, degree of fertilization, and degree of hatching. The results showed that the generation treatment did not affect the egg diameter, fecundity, fertilization rate, and hatching rate (P>0.05). However, a significant difference (P<0.05) of hatchability was observed between the domesticated generation (G-1 and G-2) and the wild generation (G-0).

Pengendalian penyakit infeksi Aeromonas hydrophila pada ikan budidaya air tawar belum sepenuhnya tertangani dengan baik. Upaya alternatif untuk mencegah penyakit infeksi A. hydrophila, maka dicoba menggunakan bahan alami berupa daun Sonneratia alba yang merupakan tumbuhan mangrove. Tumbuhan tersebut disinyalir mampu menghambat pertumbuhan bakteri patogen baik gram negative maupun gram positif. Tujuan dari penelitian ini adalah mengetahui senyawa kimia dan menguji daya hambat daun S. alba terhadap pertumbuhan A. hydrophila. Penapisan senyawa kimia diuji dengan metode kualitatif dan uji daya hambat bakteri ditentukan dengan metode difusi cakram. Analisis hasil penapisan fitokimia kualitatif menunjukkan bahwa ekstra ketanol daun S. alba mengandung tanin, steroid, alkaloid, flavonoid dan saponin. Aktivitas antibakteri dilakukan terhadap diameter zona hambat yang terbentuk di sekitar kertas cakram. Hasil penelitian menunjukkan bahwa ekstrak daun S. alba memiliki potensi dalam menghambat pertumbuhan A. hydrophila dengan zona hambat terbesar yaitu 15,67 mm pada konsentrasi 10.000 mg/LAeromonas hydrophila infections in freshwater aquaculture have not been fully controlled. Several alternatives are available and could be used to prevent A. hydrophila infection, one of which is using the natural ingredients in the leaves of Sonneratia alba, a tropical mangrove plant. The chemical compounds in plant’s leaves were suspected to be capable of inhibiting the growth of pathogenic bacteria both gram-negative and gram-positive. The purpose of this study was to determine these chemical compounds and test their inhibitory capabilities on the growth of A. hydrophila. Screening of chemical compounds was done using qualitative methods, and bacterial inhibitory tests were determined by the disk diffusion method. Results of the qualitative phytochemical screening showed that ethanol extract of S. Alba leaves contained tannins, steroids, alkaloids, flavonoids and saponins. Antibacterial activity was carried out by measuring the inhibition zone diameter. The results showed that S. alba leaf extract had the potential to inhibit the growth of A. hydrophila where the largest inhibitory zone was 15.67 mm at a concentration of 10,000 mg/L

Salah satu varietas unggul ikan mas adalah “Mustika”. Varietas ini merupakan hasil seleksi berbasis marka molekuler untuk karakter tahan penyakit KHV (Koi Herpesvirus). Pengembangan ikan mas Mustika di masyarakat memerlukan informasi terkait performa fenotipe varietas tersebut di lingkungan budidaya yang beragam. Penelitian ini bertujuan mengevaluasi adaptabilitas dan stabilitas produksi ikan mas Mustika pada beberapa kondisi lingkungan budidaya. Penelitian dilakukan di empat lokasi dengan dua model sistem budidaya berbeda, yaitu karamba jaring apung (KJA) di tiga lokasi (Waduk Cirata, Cianjur; Waduk Jatiluhur, Purwakarta; dan Waduk Darma, Kuningan) serta di kolam air deras (KAD) di Tanjungsiang, Subang. Ikan mas Majalaya yang berasal dari unit pembenihan rakyat (UPR) di masing-masing lokasi uji digunakan sebagai pembanding. Penelitian dilakukan selama 90 hari dengan tiga kali pengulangan. Berdasarkan hasil penelitian ini, ikan mas Mustika mempunyai daya adaptabilitas dan stabilitas yang baik pada semua kondisi lingkungan budidaya. Hal ini diindikasikan dengan nilai koefisien regresi (bi) karakter daya hasil panen tidak berbeda nyata dengan satu dan simpangan baku koefisien regresi (S2di) sama dengan nol. Berdasarkan hasil tersebut, budidaya ikan mas Mustika tidak membutuhkan spesifikasi lokasi tertentu dan dapat dilakukan di semua lokasi budidaya.“Mustika” is a new superior common carp variety genetically selected as KHV (Koi Herpesvirus) resistant. This research was conducted to evaluate the adaptability and production stability of the fish strain in different farming systems and sites. The treatments consisted of culturing the fish strain at four locations with two different culture systems, that is in floating net cage at three locations (Cirata Reservoir, Cianjur; Jatiluhur Reservoir Purwakarta; and Darma Reservoir, Kuningan) and in a running water pond (KAD) at Tanjungsiang, Subang. Majalaya carp produced from a local hatchery (U.P.R.) in each location was also cultured as the control treatment. All treatments in this experiment were conducted for 90 days with three replications. The results showed that Mustika common carp has high adaptability and production stability in all culture systems and sites. Such results were indicated by the coefficient of regression (bi) of biomass at harvest was not significantly different from 1.0, and the standard deviation of regression (S2di) was zero. Based on these results, it is concluded that the culture of Mustika common carp does not require a strict or specific culture system and can be farmed in most of suitable culture environment.

Pembesaran ikan lele Afrika (Clarias gariepinus) di Indonesia menghasilkan keuntungan usaha yang rendah karena tingginya harga pakan komersial berkadar protein tinggi, sehingga perlu dibentuk strain baru yang pembesarannya dapat dilakukan menggunakan pakan berkadar protein rendah melalui program seleksi. Populasi dasar ikan lele Afrika yang pembesarannya menggunakan pakan buatan komersial berkadar protein rendah (12%) telah dilakukan melalui seleksi individu. Penelitian ini bertujuan untuk mengevaluasi heritabilitas dan respons seleksi pertumbuhan dari keturunan populasi dasar (populasi seleksi) tersebut. Masing-masing sebanyak enam pasang populasi dasar dan populasi kontrol dipijahkan. Larva dari setiap pasangan induk dipelihara selama tiga minggu tahap pemeliharaan larva dan satu bulan tahap pendederan. Selanjutnya, pada tahap pengujian sebanyak 150 ekor benih dari setiap pasangan induk dipelihara selama tiga bulan dengan menggunakan pakan buatan komersial berkadar protein 12%. Hasil pengujian ini menunjukkan bahwa populasi seleksi memiliki keragaan pertumbuhan (bobot akhir 35,35 ± 2,22 g dan laju pertumbuhan spesifik 1,83 ± 0,08%/hari) dan rasio konversi pakan (5,36 ± 0,94) yang relatif lebih baik daripada populasi kontrol (bobot akhir 30,37 ± 2,52 g; laju pertumbuhan spesifik 1,77 ± 0,14%/hari dan rasio konversi pakan 5,43 ± 1,05); dengan sintasan yang relatif sama (54,56 ± 2,21% pada populasi seleksi dan 54,78 ± 6,30% pada populasi kontrol). Respons seleksi (sebesar 6,00%) dan heritabilitas nyata (sebesar 0,11) karakter bobot akhir selama tahap pembesaran tersebut relatif rendah, sehingga perlu ditindaklanjuti dengan seleksi famili.Grow-out farming of the African catfish (Clarias gariepinus) in Indonesia generally resulted in low economic return due to high cost of feeds containing high dietary protein levels. Thus, a new strain capable of using low dietary protein levels for optimal growth needs to be developed via selection programs. A base population of the African catfish fed with a low dietary protein level (12%) during the grow-out phase has been produced via individual selection. The present study was carried out to evaluate the heritability and response to selection for growth in the offspring of the base population (selected population). Six pairs of the base and control populations were selected and spawned. The produced larvae from each pair of both populations spent three weeks of larval rearing and four weeks of nursery phase. Post nursery phase, 150 juveniles from each pair were fed with a commercial feed containing 12% crude protein for three months of grow-out phase. During the grow-out phase, the selected population exhibited higher growth performances (final body weight of 35.35 ± 2.22 g and specific growth rate of 1.83 ± 0.08%/day) and relatively lower feed conversion ratio (5.36 ± 0.94) than the control population (final body weight of 0.37 ± 2.52 g, specific growth rate of 1.77 ± 0.14%/day and feed conversion ratio of 5.43 ± 1.05). The selected and control populations had a relatively similar survival rates of 54.56 ± 2.21% and 54.78 ± 6.30%, respectively. The response to selection (6.00%) and realized heritability (0.11) values for the final body weight during the grow-out phase were considered relatively low. Therefore, future research should continue to improve the findings of this research through family selection.

Limbah pendederan ikan nila terdapat kelimpahan nutrien yang mampu dimanfaatkan oleh perifiton. Perifiton mampu menjaga kualitas air dan dapat dimanfaatkan sebagai pakan tambahan ikan nila. Substrat yang baik memengaruhi pertumbuhan perifiton. Salah satu jenis substrat yang dapat digunakan adalah tali rafia. Tujuan dari penelitian ini adalah mengevaluasi jarak tali rafia terhadap pertumbuhan perifiton. Penelitian dilakukan secara eksperimental dengan menggunakan rancangan acak lengkap (RAL) dengan perlakuan perbedaan jarak substrat tali rafia 15 cm, 25 cm, dan 35 cm. Berdasarkan hasil penelitian diperoleh nilai tertinggi untuk kelimpahan perifiton pada perlakuan 25 sebesar 10.779.375 sel cm-2, indeks keanekaragaman sebesar 1,90 sel cm-2, dan indeks keseragaman sebesar 0,69 sel cm-2. Perifiton yang teridentifikasi di antaranya kelas Cyanophycea (empat genus), Bacillariophyceae (lima genus), Chlorophyceae (lima genus), Protozoa (tiga genus), dan Rotifera. Substrat dengan jarak 25 cm merupakan jarak optimal dalam pertumbuhan perifiton selama 35 hari pada kolam budidaya. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa substrat tali rafia dengan jarak 25 cm menghasilkan pertumbuhan perifiton terbaik yang berpotensi sebagai pakan alami di lingkungan pendederan ikan nila Oreochromis niloticus.Feed and faecal wastes in the nursery media of nile tilapia Oreochromis niloticus are highly concentrated nutrients that could be utilized by naturally occurring periphyton. Periphyton can absorb the nutrients, maintain the water quality and be used as additional food for the cultured tilapia. Suitable substrate influences the growth of periphyton. One type of substrates that can be used is plastic/polypropylene raffia strings. The aim of this study was to evaluate different distance set up between raffia strings on periphyton growth. The experiment was arranged in a completely randomized design (CRD) consisting of varying distance set up of plastic raffia strings, i.e., 15 cm, 25 cm, and 35 cm as the treatments. The results show that the highest growth value was achieved by periphyton in raffia strings placed at 25 cm apart with a density of 10,779,375 cells cm-2, diversity index of 1.90 cell cm-2, and uniformity index of 0.69 cell cm-2. The periphyton identified included Cyanophycea (four genera), Bacillariophyceae (five genera), Chlorophyceae (five genera), Protozoa (three genera), and Rotifera. This current research recommends that the optimal distance between plastic raffia strings as periphyton substrate should be at 25 cm. Based on this study result, it can be concluded that raffia rope substrate with 25 cm distance produces the best periphyton that is potentially utilized as natural feed in nile tilapia Oreochromis niloticus rearing environment.
