Abstract

Tujuan dari penelitian ini untuk mengetahui pengaruh frekuensi pemberian bioflok yang berbeda terhadap kelangsungan hidup dan pertumbuhan larva ikan papuyu (Anabas testudineus Bloch 1792). Penelitian dilaksanakan di Laboratorium Basah Jurusan Akuakultur Fakultas Perikanan dan Kelautan Universitas Lambung Mangkurat. Pemeliharaan larva ikan papuyu dilakukan dalam wadah baskom berdiameter 45 cm dengan media berupa air bersih dan setiap baskom dimasukkan larva ikan papuyu sebanyak 200 ekor/baskom. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan yaitu frekuensi pemberian pakan sebanyak 2 kali/hari (Perlakuan A), sebanyak 4 kali/hari (Perlakuan B) dan sebanyak 6 kali/hari (Perlakuan C) dan 3 ulangan. Hasil penelitian menunjukkan bahwa media bioflok tidak memiliki pengaruh nyata terhadap kelangsungan hidup larva ikan papuyu, ini dilihat dari Fhitung = 0,351852 < Ftab 5% (5,409451) dan Ftab 1% (12,05995). Sedangkan pertumbuhan larva ikan papuyu berpengaruh nyata terhadap larva ikan papuyu dilihat dari Fhitung = 39358,54 > Ftab 5% (5,409451) dan Ftab 1% (12,05995). Kualitas air media hidup larva ikan papuyu masih pada batas toleransi yang diinginkan ikan uji pada media penelitian, dimana suhu (27,7 – 27,90C), DO (4,8 – 4,9 mg/L), pH (7,5) dan amoniak (<0,6 mg/L) The purpose of this study was to determine the effect of different frequency of biofloc on the survival and growth of fish larvae (Anabas testudineus Bloch 1792). This research was done in the Wet Laboratory of Aquaculture Department, Fisheries and Marine Faculty, Lambung Mangkurat University. The maintenance of papuyu fish larvae was carried out in a basin with diameter 45 cm in with media in the form of clean water and each basin is inserted as many as 200 fish / climbing perch larvae / basin. The study used a Completely Randomized Design (CRD) with 3 treatments, namely the frequency of feeding as much as 2 times / day (Treatment A), as much as 4 times / day (Treatment B) and as many as 6 times / day (Treatment C) and 3 replications. The results showed that the biofloc media did not have a significant effect on the survival of climbing perch larvae, this was seen from F count = 0.351852 <Ftab 5% (5.409451) and Ftab 1% (12.05995). While the growth of climbing perch larvae significantly affected climbing percch larvae seen from F count = 39358.54> Ftab 5% (5.409451) and Ftab 1% (12.05995).

Abstract

Climbing perch enlargement activities are constrained by available fry, due to insufficient production. One of the unknown aquaculture factors is the best water level that can be used in spawning activities for climbing perch. The purpose of the study was to determine the effect of water level manipulation on the spawning results of climbing perch carried out naturally. The study used 3 treatments, namely water levels of 40 cm, 50 cm, and 60 cm and each treatment was repeated 4 times, while the parameters observed included fecundity, egg diameter, fertilization rete, hatching rate, survival rate, and water quality. The results showed that fecundity, egg diameter, fertilization rate, the highest hatching rate were obtained at treatment B of 26419.50 eggs, 0.63 mm, 59.50%, and 41.25%, respectively, while the highest survival rate was obtained in treatment A, which was 71.00%. Water quality during the study was still at the tolerance limit that supports the spawning of climbing perch, namely temperatures between 25.2 – 26.2oC, pH between 7.05 – 7.34, and DO between 3.77 – 4.21 mg / L. Based on diversity analysis (ANOVA) it shows that Fhitung < Ftabel is stated to be no real difference between all treatments given (receive H0) and the results of regression tests show that a water level of 45 cm is optimal for natural spawning of climbing perch Kegiatan pembesaran ikan papuyu terkendala dengan benih yang tersedia, karena produksinya yang tidak mencukupi. Salah satu faktor budidaya perairan yang belum diketahui adalah ketinggian air yang terbaik yang dapat digunakan dalam kegiatan pemijahan ikan papuyu. Tujuan penelitian untuk mengetahui pengaruh manipulasi ketinggian air terhadap hasil pemijahan ikan papuyu yang dilakukan secara alamiah. Penelitian menggunakan 3 perlakuan, yakni ketinggian air 40 cm, 50 cm, dan 60 cm serta masing-masing perlakuan diulang sebanyak 4 kali, sedangkan parameter yang diamati meliputi fekunditas, diameter telur, derajat pembuahan, derajat penetasan, survival rate, dan kualitas air. Hasil penelitian menunjukkan bahwa fekunditas, diameter telur, derajat pembuahan, derajat penetasan tertinggi diperoleh pada perlakuan B masing-masing 26419,50 butir, 0,63 mm, 59,50%, dan 41,25%, sedangkan survival rate tertinggi diperoleh pada perlakuan A, yakni 71,00%. Kualitas air selama penelitian masih berada pada batas toleransi yang menunjang pemijahan ikan papuyu yaitu suhu antara 25,2 – 26,20C, pH antara 7,05 – 7,34, dan DO antara 3,77 – 4,21 mg/L. Berdasarkan analisis keragaman (ANOVA) menunjukan bahwa Fhitung < Ftabel dinyatakan tidak berbeda nyata antara semua perlakuan yang diberikan (terima H0) dan hasil uji regresi menunjukkan bahwa ketinggian air 45 cm adalah optimal untuk pemijahan ikan papuyu secara alamiah.

Abstract

Feed is the main need, which accounts for 60-70% of the total aquaculture production costs. In general, fish farming groups (Pokdakan) depend on artificial feed. High feed prices are not balanced with the selling price of fish. This is because Pokdakan does not yet understand floating feed and the operational techniques of floating feed machines. This is a problem encountered, including in Pokdakan Papuyu Sakti. So that Pokdakan Papuyu Sakti members can increase production, feed quality and the sustainability of the use of floating feed, technical guidance is needed. The aim is to increase the ability to provide quality floating feed that is sufficient for cultivation activities. The scope of solutions offered is counseling, demonstration of machine use, and making floating feed. The partners' level of knowledge and skills were evaluated based on the Guttman Scale. The evaluation results show that the introduction of machines and the manufacture of floating feed have been successfully implemented, there has been an increase in knowledge understanding > 75% or an increase of seven times from the start of the activity. The skills of Pokdakan members in carrying out the practice of making floating food increased four times.

Abstract

Kelabau is a species of indigenous fish from Kalimantan and Sumatra that is now rarely found in rivers. This is due to the fishing by fishermen who are less selective for years without being balanced with cultivation efforts. Cultivations have several aspects that need to be considered, namely the availability of feed that contains good nutrients and is in accordance with the needs of fish. Kelakai is an alternative that can be used as additional feed for kelabau. the use of the biofloc system is also rarely done in kelabau farming. The combination of kelakai leaf silage and biofloc system has the potential to increase the efficiency of kelabau farming by applying environmentally friendly technology. The study aims to analyze the growth performance of kelabau. The research was carried out in the Wet Laboratory located at the Faculty of Fisheries and Marine Science, Lambung Mangkurat University, Banjarbaru City, South Kalimantan Province. The research method used was an experimental approach with a Completely Randomized Design (RAL), consisting of 3 treatments which were repeated 3 times, so that a total of 9 experimental units were obtained, where Treatment K (Control) is commercial feed given at a dose of 5% of biomass weight, Treatment A is kelakai leaf silage at a dose of 5% of biomass weight, and Treatment B is commercial feed + kelakai leaf silage at a dose of 2.5% of biomass weight. The research results showed the best results in relative length of 121.5%, relative weight of 24.0%, and feed utilization efficiency of 47.3%. FCR showed the best results in treatment K of 0.68% and the best survival rate in treatments K and A of 99.3%. Treatment B can be considered as an alternative feed for the cultivation of kelabau in biofloc systems because it can improve growth performance.

Abstract

Abstract. Research and development of biofloc aquaculture system until now only in the range of 14-15 species conducted. Even though this technology is able to increase production several times compared to conventional systems, so it is necessary to diversify species that allow development, especially economically important fish. There are 4 species of fish that are feasible to be developed, especially freshwater fish groups in wetlands, such as fish (climbing perch; Anabas testudineus Bloch, snakehead, Channa striata Bloch, giant gouramy , Opronemus gouramy and Pangas , Pangasius hypophthalmus. This research has been carried out in the range of June 2023- February 2024 using a complete randomised complete block design, 4 treatments climbing perch; snakehead, giant gouramy and pangas with 4 replicates. Stocking density of 1000 fish 2500 L-1 using 2 m diameter round pond with biofloc media; feeding twice a day and the amount of feed given was 2.5% of total weight, for 158 days. Research parameters included; daily growth rate (%/day), feed efficiency. FCR, weight gain (gr) and length gain (cm), water quality and biofloc content (ml/L). The results showed that the results of the anova test showed a significance value (Sig.) of 0.000 0.05, so there was a significant difference between treatments of the daily growth rate (SGR) parameter, the results of the area test also showed differences between treatments. The highest daily growth rate was obtained in climbing perch, followed by pangas, giant gouramy and Snakehead. The results of the anova test for weight gain showed a significance value (Sig.) of 0.000 0.05, so there was a significant difference between treatments. The anova test results showed a significance value (Sig.) of 0.052 0.005, so there was no significant difference between treatments; the growth of each treatment showed peculiarities between species depending on genes. Anova test results show that the feed conversion of fish research significance value 0.000 0.05 means that the four types of fish studied, significantly different from those reared in the biofloc system Survival rate of fish research significance value 0.000 0.05 means that the four types of fish studied, significantly different from those reared in the biofloc system. Water quality with 4 main parameters is able to support the growth and development of the 4 economically important fish species studied.
