Abstract

Typical constraints on eel cultivation are high mortality and slow growth rates. The purpose of this study was to determine the best light intensity for the increase in the survival rate and growth of glass eel (Anguilla bicolor bicolor). This research was conducted at Multi-Species Hatchery (MSH) Environmental Technology Research Installation and Toxicology of Freshwater Aquaculture Cibalagung, Bogor City. The research design used is a Complete RandomIzed Plan (RAL) of four treatments and three replication. Treatment A (250 Lux), treatment B (500 Lux), treatment C (750 Lux), treatment K (Without light intensity). Glass eel is kept for 50 days. The parameters and data analyzed statistically include specific growth rate (SGR), absolute length growth, absolute weight growth and survival rate (SR). The data is analyzed using a variety analysis (ANOVA). If obtained, a significant result (P<0.05) is conducted Duncan multiple range test. In addition, water quality parameters (DO, temperature and pH) are descriptively analyzed. Based on the results of the experiment, light affects the growth of both length and weight. The optimal light intensity for long growth and weight loss, i.e. C (750 Lux) treatment, produces the highest value and differs markedly from the A (250 Lux), B (500 Lux) and K (No light intensity) treatments in absolute weight growth parameters (0.37± 0.01 g), the rate of growth of specific weights (1.76±0.01 % / day), the total length (1.8±0.14 cm) and the specific length growth rate (3.41±0.05 % / day). However, for the highest contention obtained in treatment K (without light intensity) with a value of 66%, the value produced a result that differed markedly from other treatments.

Abstract

Ikan bawal bintang menjadi komoditi yang diunggulkan pada budidaya air laut Indonesia selain ikan kerapu dan kakap putih. Penambahan probiotik dapat menambah pertumbuhan dan efiensi pakan. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan probiotik EM-4 (Effective Microorganism-4) dengan dosis yang berbeda terhadap benih ikan bawal bintang. Penelitian ini dilaksanakan pada Maret-September 2021 dengan masa percobaan 25 Maret-25 April 2021. Rancangan percobaan menggunakan  rancangan acak lengkap dengan 4 perlakuan dan 4 ulangan, Perlakuan meliputi K (kontrol), PB30 (30 mL probiotik/kg pakan), PB40 (40 mL probiotik/kg pakan), dan PB50 (50 mL probiotik/kg pakan). Ikan bawal bintang yang digunakan berukuran panjang 4 cm dan bobot 2,24-2,28 g.  Parameter uji yaitu laju pertumbuhan bobot spesifik (LPBS), pertumbuhan bobot mutlak (PBM), laju pertumbuhan panjang spesifik (LPPS), pertumbuhan panjang mutlak (PPM), dan kelangsungan hidup. Data dianalisis menggunakan analisis ragam, apabila berbeda nyata diuji lanjut dengan uji Beda Nyata Terkecil. Hasil penelitian menunjukkan bahwa pemberian probiotik dengan dosis berbeda berpengaruh secara nyata (P<0,5) terhadap pertumbuhan dan kelangsungan hidup bawal bintang. Kinerja pertumbuhan (LPBS 3,3413±0,030%/hari, LPPS 2,2513±0.020%/hari, PBM 3.57±0.41 g, dan  PPM 3.51±0.43 cm) terbaik terjadi pada perlakuan PB50 dengan pemberian dosis probiotik 50 mL/kg pakan.

Abstract

Ikan Corydoras sterbai memiliki permintaan pasar yang tinggi akan tetapi masih diproduksi dengan kepadatan rendah sehingga produksinya rendah. Penelitian bertujuan untuk mengetahui kinerja produksi benih ikan Corydoras sterbai dengan padat tebar berbeda. Penelitian dilakukan pada bulan Maret sampai bulan Agustus 2021, masa percobaan 28 hari pada 11 Maret 2021 sampai 07 April 2021. Penelitian menggunakan Rancangan Acak Lengkap dengan 4 perlakuan padat tebar (4 ekor/L, 6 ekor/L, 8 ekor/L, dan 10 ekor/L) dan 3 kali ulangan. Ikan uji adalah benih ikan Corydoras sterbai berukuran panjang rata-rata 2 cm dan bobot 0,24 g-0,28 g yang berasal dari Dinda Aquatic. Ikan dipelihara dalam akuarium berukuran 20x20x20 cm3, diberi pakan cacing sutra secara ad libitum. Data penelitian diuji menggunakan analisis ragam (ANOVA), antar perlakuan yang berbeda nyata diuji lanjut dengan uji BNT (Beda Nyata Terkecil). Parameter uji meliputi laju pertumbuhan bobot spesifik, laju pertumbuhan panjang spesifik, efisiensi pakan, dan tingkat kelangsungan hidup. Hasil penelitian menunjukkan padat tebar berbeda berpengaruh nyata (P<0,05) terhadap laju pertumbuhan bobot spesifik, laju pertumbuhan panjang spesifik dengan hasil perlakuan A, B, dan C tidak berbeda nyata, namun berbeda nyata dengan perlakuan D. Efisiensi pakan dengan hasil perlakuan A, B tidak berbeda nyata, namun berbeda nyata dengan perlakuan C dan D. Padat tebar tidak berpengaruh nyata (P>0,05) terhadap tingkat kelangsungan hidup benih ikan Corydoras sterbai.

Abstract

One of the obstacles faced in the cultivation of freshwater crayfish , especially in enlargement is the right feeding rate that can improve growth performance. This study aims to evaluate the growth performance of freshwater crayfish with different feeding rates. This research was conducted in Cicareuh Village, Cikidang District, Sukabumi Regency. with 3 treatments, namely feeding rate 1%, 2.5%, and 4% for 40 days. Parameters observed in this study were specific growth rate, absolute weight growth rate, absolute length growth, absolute weight growth, feed efficiency, survival and water quality. This study was analyzed by ANOVA and Tukey's further test. In general, different feeding rates have a significant effect on growth performance and FR 4% is the best feeding rate in this study.

Abstract

Feed that has a high nutritional content can increase fish growth. One of the natural feeds that can be used is maggot which can be given to fish and can be cultivated by humans so that its availability is always continuous. This research aims to find out the combination of maggot feed with commercial feed as an effort to reduce feed costs in aquaculture activities. This research was conducted in March November 2022 with a trial period of 28 days on May 9 June 9, 2022. This study used a completely randomized design with 4 treatments (40% maggot + 60% commercial feed, 50% maggot + 50% commercial feed, maggot 60% + 40% commercial feed, and Control) and 3 replications. The fish used were Nile Tilapia measuring 4.00 g obtained from the Bayongbong Fisheries Technical Implementation Unit and then randomly stocked into 12 containers. The test parameters included length growth, weight growth, specific weight growth rate, feed efficiency, and survival rate. The results showed that giving maggot combined with commercial feed had a significant effect on the length growth, weight growth, and specific weight growth rate (P<0.05). The best growth was found in treatment of 50% maggot + 50% commercial feed (length growth 3.500 ± 0.100 cm, weight growth 4.400 ± 0.111 g, and specific weight growth rate 3.780 ± 0.017%/day). The combination of maggot and commercial feed had no significant effect (P>0.05) on the survival rate and feed efficiency of Nile Tilapia.
