Abstract

Wastewater from vaname shrimp culture with a semi biofloc system, was used for milkfish cultivation without additional feed. Fish seeds are stocked 4000 with 18 days of age. The Milkfish pond is 2000 m2, the water level is 0,7 m. Water quality was observed 2 months cultivation. Water samples were taken everyweeks around 9 am, from March to April 2022. During the research, temperature, brightness, pH, dissolved oxygen, CO2 and salinity were relatively stable, except for nitrate and phosphate levels. First observation the levels of nitrate were 0,059 mg/l and phosphate was 0,064 mg/l. When the fish were 2,5 months, nitrate levels increased by 425,4% to 0,31 mg/l and phosphate increased by 479,7% to 0,371 mg/l. This increase is thought the addition of residual water from vannamei shrimp cultivation, so that the pond water level becomes 80 cm. Observation of milkfish at the age of 3 months, nitrate levels decreased 42,6% to 0,178 mg/l and phosphate decreased 8,4% to 0,34 mg/l. This decreasing is thought because nitrate and phosphate are used as a source of nutrients for phytoplankton. The milkfish are 3,5 months, the nitrate level decreases by 58,4% to 0,074 mg/l, but the phosphate level increases by 8,24% to 0,368 mg/l. The increase in phosphate is thought to be from the decomposition of fish feces. And the decreasing of nitrate because used as a source of nutrients for phytoplankton. Water quality monitoring must be carried out regularly, to preserve pond water quality.

Abstract

Poecilia sp. is one type of ornamental fish that has distinctive characteristics because molly fish are freshwater ornamental fish that are able to live and breed in saline (brackish water) environments. Induction of molly fish spawning can be done with salinity treatment on the spawning media because the endocrine system in molly fish which plays a role in regulating body balance against changes in environmental conditions, especially changes in salinity will become more active so that it affects metabolism and reproduction (Taufik & Kusrini, 2006). The purpose of this study was to analyze differences in salinity as a spawning stimulant in molly fish. the method used in this study: P1. Salinity 10 ppt, P2. Salinity 15 ppt, P3. salinity 20 ppt, P4. Salinity 25 ppt, P5. 30 ppt with three replications. Parameters observed were Gonad Maturity Level (TKG), Gonad Maturity Index (IKG), survival rate (SR), and gestation period. The reared fish showed good gonad maturity so that spawning occurred. The results of this study, the highest gonadal maturity level was found at P1 salinity 10 ppt and P2 salinity 15 ppt the best, namely TKG V compared to P3, P4, and P5 namely TKG IV. The best gonadal maturity index was treatment P1 which was 14.28±2.0c followed by P2 11.71±2.0bc, P3 10.74±0.76abc P5 8.01±2.34ab and P4 7.27±2, 84a. The fastest gestation period was in P1 and P2, namely 44 days and 23 days. The highest survival rate occurred in P1 and P2, which was 100%. The highest absolute weight average was found in P1 which was 8.01±0.82c P2 6.33±0.5bc. The conclusion of this study, different salinity has a significant effect on the gonadal maturity index and absolute weight of golden black molly fish.

Abstract

Ornamental fish is a fish that is much favored by the public because it has a beautiful color. The demand for ornamental fish is increasing every year both in the domestic and international markets, based on data from the KKP in 2018 the export value of hyacinth reached USD 32.23 million and in 2020 Indonesia targets to produce 1.8 billion ornamental fish. One of the ornamental fish that is much favored by the public is Betta fish (Betta sp). From an economic point of view, male betta fish cultivation is less profitable because of its poor body color and morphology. Male betta fish are more popular than female fish, because they have advantages in terms of color and morphology. Based on the results of the study, it was found that the highest male sex presentation of betta fish was in treatment P4 with a total of 91.11% followed by treatment P5 with a total of 73.33% treatment P3 78.89% to treatment P2 58.89% male and followed by male sex presentation the lowest was found in treatment P1 with a total of 35.56%.

Abstract

There are still catfish hatcheries found in Tegal District that use brooders derived from the results of rearing spread seeds (jonggolan), not catfish specifically for certified breeders. The use of jonggolan as broodstock is feared to cause a decrease in the quality of catfish fry due to inbreeding or inbreeding. This research is expected to be able to determine the factors that influence the use of certified catfish broodstock so that prevention can be done to avoid losses to catfish farmers and improve the steps that need to be decided in making policies at the relevant agencies.This study uses a descriptive correlational statistical analysis method. The data was taken from all catfish hatcheries in Tegal District with a total of 100 respondents then the data was processed with SPSS 24 year 2022 software.The variables of age, last education, training or socialization about fisheries that have been followed, and the origin of the broodstock used have a significance value greater than 0.05. then there is no significant correlation (relationship) to the parental strain variable used. The Capital Estimation variable has a significance value less than 0.05 (Sig. 0.000). then there is a significant correlation (relationship) to the parental strain variable used. Spearman correlation value of 0.351 indicates that the direction of the correlation is positive with a weak correlation strength.Age factor, last education, training or socialization by the Fisheries Service that has been followed, the origin of the broodstock (government assistance, independent purchase or jonggolan) does not affect the use of certified catfish breeders. Capital owned factors that influence the decision of farmers in using certified catfish broodstock.

Abstract

Fitoplankton adalah salah satu mikroorganisme autotrof yang perperan penting dalam mengubah bahan anorganik menjadi bahan organik yang hidup melayang di permukaan perairan. Penelitian ini bertujuan untuk mengetahui kelimpahan, keanekaragaman, keseragaman, dan dominansi fitoplankton di Perairan Desa Baruta Analalaki, Kecamatan Sangia Wambulu Kabupaten Buton Tengah. Penelitian dilaksanakan mulai bulan Oktober sampai dengan November 2022. Alat yang digunakan yaitu Seichidisk, Termometer, Refraktometer, dan Planktonnet. Bahan yang digunakan dalam penelitian adalah sampel air yang diambil dari lokasi dan sudah ditentukan pada saat pagi, siang, dan sore hari. Metode yang digunakan dalam penelitian ini adalah metode purposive random sampling, yaitu Metode yang digunakan untuk memudahkan peneliti dalam menentukan lokasi sampling sesuai dengan kriteria yang diinginkan oleh peneliti (Hadi, 2004). Hasil penelitian Menunjukkan bahwa ditemukan tiga kelas fitoplankton yaitu dari kelas Bacillariophyceae, Chlorophyceae, dan Dinophyceae. Dari ketiga kelas tersebut yang paling banyak ditemukan dari kelas Bacillariophyceae. Tingkat kelimpahan fitoplankton tergolong cukup subur yakni terjadi pada siang hari pada jam 12.00-14.00 ditemukan 968-1120 jenis, sedangkan pada pagi dan sore hari justru kelimpahan fitoplankton tergolong sedang. Indeks keanekaragaman rata-rata masuk kategori sedang, namun pada jam 14.00 ditemukan indeks keanekaragaman tinggi yaitu 3,05. Selanjutnya indeks keseragaman menunjukkan kategori rendah. Hal ini disebabkan karena adanya persaingan ruang dan makanan antar jenis fitoplankton. Dominansi pun tergolong rendah artinya tidak ada spesies yang mendominasi. Uji korelasi Pearson antara kelimpahan fitoplankton dan parameter kualitas air memiliki kaitan yang sangat kuat dengan nilai r = 0,715 (kecerahan), dan r = 0,526 (suhu). Analisis regresi memiliki persamaan Y = 1761+183X1+126X2. Hasil tersebut menunjukkan koefisien perbandingan kecerahan dan suhu bernilai positif yang artinya jika terjadi peningkatan sebesar 1 cm maka tingkat kelimpahan fitoplankton akan naik sebesar 183 atau 126 dengan asumsi parameter lainnya konstan. Berdasarkan hasil tersebut, nilai kecerahan dan suhu yang tinggi menunjukkan kelimpahan fitoplankton juga tinggi di Perairan Desa Baruta Analalaki.

Abstract

The need for carp (Cyprinus carpio) from year to year continues to increase with the increase in population. Consumer demand for fish consumption has experienced a shift, from fresh (frozen) fish to live fish. The obstacles often faced by cultivators are death before the fish arrive at their destination, the cause of fish death is due to stress and physical damage due to mishandling. To avoid the high mortality rate of carp during the transportation process, fish entrepreneurs have begun to develop a dry transportation system, namely a system of transporting live fish using non-water transportation media. In the transportation of live fish without water media, the fish are made in a state of calm or stunning. Anesthesia can be done by giving an anesthetic in which the fish becomes unconscious during the transportation process. The advantage of stunning this fish is that it makes it easier to carry out the transportation process without water media, makes the fish not move much during the transportation process and minimizes the risk of fish being injured so as to allow a longer transportation time. One of the natural ingredients that can be used for anesthesia is tobacco (Nicotiana tabacum). The purpose of this study was to determine the effect of anesthetic tobacco extract (N. tobacum) on the hematological condition of carp (C. carpio) by dry transportation method. The treatments tested were soaking tobacco extract as fish anesthetic before transportation with different concentrations, namely, in treatment 1 (P1) without soaking tobacco extract, treatment 2 (P2) soaking tobacco extract 1 ml, treatment 3 (P3) soaking tobacco extract 2 ml, treatment (P4), soaking extract 3 ml. The results of this study that the use of tobacco leaf extract as an anesthetic in the dry transportation system causes hematological levels to increase and decrease but are still in normal levels, the best dose of tobacco extract is 1ml/L with a stunning speed of 917 minutes, recovery time is 239 minutes and has an SR value of 76%.

Abstract

West Nusa Tenggara Province has potential seaweed resources. This study aims to analyze the yield of carrageenan at different cultivation ages. West nusa tenggara province has an area for seaweed cultivation of 25,206.6 ha. The area is spread over the districts of East Lombok, west Lombok, central Lombok, Sumbawa, Dompu, Bima, the city of Mataram, the city of Bima, west Sumbawa and north Lombok. Seaweed is a chlorophyll plant and is classified as a low-level plant that has no true roots, stems or leaves, but only resembles a stem called a thalus. This research was conducted in Ekas Bay, Ekas Buana Village, Jerowaru District, East Lombok, and West Nusa Tenggara. This study used a completely randomized design (CRD) with 4 treatments: P1: 15 days, P2: 25 days, P3: 35 days, and P4: 45 days. The yield of K. alvarezii carrageenan obtained the highest score in treatment (P4), which was 53.4%. The chlorophyll content of K. alvarezii seaweed obtained the highest value in treatment (P4), namely 5.1 mg/L. Based on the results of research data analysis, it was found that the different cultivation ages of Kappaphycus alvarezii had a significant effect on absolute growth, specific growth and no significant effect on carrageenan content. In this study, the P4 treatment (45 days) obtained an absolute growth of 149 g, a specific growth of 5.46%, and a carrageenan content of 53.4%, and the best chlorophyll content value was 5.1 mg/L. The conclusion of this study is the best maintenance in this study, namely treatment P4 (45 days) obtained absolute growth of 149 grams, specific growth of 5.46%, and carrageenan content of 53.4%, and the best value of chlorophyll content is 5.1 mg /l.

Abstract

Seaweed is one type of fishery commodity that is widely used both as a raw material for food, industry, medicine, and cosmetics. This causes the economic value of seaweed to help the community's economy and can increase the country's foreign exchange. Seaweed is one of the largest carotenoid producers because green seaweed generally contains chlorophyll a and b compounds and carotene compounds which can function as antioxidants. Factors that affect the content of carotenoids is the spacing of seaweed seeds. The purpose of this study was to determine the effect of spacing in the basic stake system on the carotenoid content of Caulerpa lentilifera and to determine the ideal spacing that gives optimal effect on the carotenoid content of Caulerpa lentilifera. This study used an experimental method with a completely randomized design (CRD) pattern with 6 treatments and 3 replications with treatments namely Control (25 cm spacing), P1 (20 cm spacing), P2 (30 cm spacing), P3 (20 cm spacing). plant 35 cm), P4 (planting distance 40 cm), P5 (planting distance 45 cm). The data obtained was then analyzed using variance (ANOVA) with a 95% confidence level and to find out the best growth a further test was carried out using the BNT test. The results showed that the spacing applied to the basic stake system had no effect on the carotenoid content of Caulerpa lentilifera, but had an effect on the absolute growth and specific growth rates. Spacing of 30 cm is the best distance for the growth of Caulerpa lentilifera with an absolute growth of 128.917 g and a specific growth rate of 4.965%, but the difference in spacing has no effect on the carotenoid content. The conclusion of this study was that the difference in plant spacing of the basic stake system had no effect on the carotenoid content of C. lentilifera, but had an effect on the absolute growth and specific growth rate. There was no ideal spacing to increase carotenoid content in C. lentilifera, because each treatment tended to have relatively the same carotenoid content.
