Snakehead fish (Channa striata) is one of economically valued freshwater fish species, which is potential to be cultivated intensively. However, it has still mirred in the production because of low survival fry rate. The current research aimed to obtain the best stocking density on the survival and growth snakehead larvae rearing in plastic lined pond. Research was conducted in Batanghari Sembilan Fish Breeding Units from 3rd June until 3rd July 2014. This research used a completely randomized design with four treatments and three replications. The treatments were P1 (2 larvae per-litre), P2 (4 larvae per-litre), P3 (6 larvae per-litre), and P4 (8 larvae per-litre). The result showed that the difference of stocking density was significant on survival rate, length and weight growth. Stocking density P1 with 2 larvae per-litre was resulted the highest-value consist of survival rate (63.83 %), absolute length growth (3.61 cm), and-absolute weight growth (3.88 g). Water quality parameters during research in optimal range were temperature 27-32oC, pH 5.2-7.8, dissolved oxygen 2.08-7.06 mg.L-1, and ammonia concentration 0.006 - 0.072 mg.L-1.

This research was conducted to determine natural food substitution time by artificial diet after salinity acclimatization from 20 ppt until 2 ppt, which can increase survival and growth of (Litopenaeus vannamei) postlarvae during rearing period. Design experiment was completely randomized design with five treatments and three replications of natural food Chironomus sp. (60% of crude protein) substitution time by artificial diet (40% of crude protein) at day: 1 (A), 7 (B), 14 (C), 21 (D) and full natural food without artificial diet (E) during 28 days rearing period. White shrimp postlarvae and rearing media in this experiment based from best result of earlier research that is PL25 from acclimatization in media 2 ppt with addition of potassium 25 ppm to freshwater media. The densities of PL25 white shrimp were 20 PLs/50 liters of 2 ppt media. The result of this experiment showed that the use of artificial diet as soon as after salinity acclimatization (PL25) gave best performance production compared to which only that was given natural food Chironomus sp. during experiment or with treatment by artificial diet substitution at day-7, day-14 or day-21, shown with the highest value of food consumption level, protein retention, energy retention, daily growth rate and food efficiency. Survival rate of PL54 was above 80% and not significant different between treatment. That is supported by chemical-physical value of water quality still in range appropriate to survival rate of white shrimp post larvae during a rearing period. The result of this experiment indicated that requirement nutrient of PL25 in low salinity did not fulfilled if only rely on natural food, so that require artificial diet with nutrition content to support growth and survival rate of white shrimp post larvae more maximal. Key words: salinity, natural food, artificial diet, Pacific white shrimp ABSTRAK Tujuan penelitian ini adalah untuk menentukan waktu penggantian pakan alami oleh pakan buatan yang tepat selama masa pemeliharaan postlarva udang vaname di media bersalinitas rendah setelah melalui masa aklimatisasi penurunan salinitas dari 20 ppt hingga 2 ppt, sehingga dapat meningkatkan pertumbuhan dan kelangsungan hidup. Rancangan percobaan berupa rancangan acak lengkap dengan perlakuan yang diterapkan berupa waktu penggantian pakan alami Chironomus sp. (kadar protein 62%) oleh pakan buatan (kadar protein 40%) pada hari ke-1 (A), ke-7 (B), ke-14 (C), ke-21 (D) dan pakan alami (E) selama masa pemeliharaan. Postlarva udang vaname dan media pemeliharaan yang dipergunakan selama percobaan mengacu pada hasil terbaik yang didapatkan dari penelitian pendahuluan yaitu berupa PL25 hasil aklimatisasi di media bersalinitas 2 ppt dengan penambahan kalium 25 ppm ke media air tawar pengencer. Padat tebar sebanyak 20 ekor/50 liter/wadah. Hasil percobaan menunjukkan bahwa pemberian pakan buatan yang diberikan segera setelah masa aklimatisasi salinitas (pada awal pemeliharaan PL25) memberikan performa produksi budidaya terbaik bila dibandingkan dengan yang hanya diberi pakan alami selama masa pemeliharaan maupun waktu penggantian pakan alami oleh pakan buatan pada hari ke-7, ke-14 dan hari ke-21 yang ditunjukkan dengan tingkat konsumsi pakan, retensi protein, retensi energi, laju pertumbuhan harian dan efisiensi pakan yang tertinggi. Kelangsungan hidup di akhir pemeliharaan (PL54) di atas 80% dan tidak berbeda nyata antar perlakuan. Hal ini ditunjang oleh nilai fisika kimia air yang berada dalam kisaran yang layak selama masa pemeliharaan. Hasil percobaan ini menunjukkan bahwa kebutuhan nutrisi pada stadia PL25 di media bersalinitas rendah tidak terpenuhi jika hanya mengandalkan pakan alami sehingga perlu ditunjang dari pakan buatan dengankandungan nutrisi yang dapat mendukung pertumbuhan dan kelangsungan hidup yang lebih maksimal. Kata kunci: salinitas, pakan alami, pakan buatan, udang vaname.

This research was conducted to determine the closed transportation system with biomass and water volume ratio that can support the osmoregulation ability of glass eel significantly. Glass eel was obtained from catching activities in the Cimandiri River, Pelabuhan Ratu (mean length 52.40+0.84 mm and weight 0.10+0.01 g) and acclimatized for 24 hours at salinity 6 mg L-1 and temperature 20°C gradually.The research design was a completely randomized design. The applied treatment was glass eel closed transportation system with various ratio of glass eel biomass (kg): water volume (L), i.e. 1:11; 1:12; 1:13; and 1:14 during 24 hours of land transportation and continued with a 3-day recovery period.The water was used refer to the above acclimatization method, with ratio the water part of pure oxygen in a plastic bag was 1:3. The measured parameters include survival rate, osmotic gradient, body hydromineral, and water quality in transport packaging and recovery medium. Survival rates were generated in the high range until recovery period (P<0.05), but the transportation method caused differences significantly (P<0.05) in osmotic response and hydromineral status (sodium, chloride, potassium, and water content), so that it will affect production performance in the next stage of culture. Ratio of glass eel biomass: water volume of 1:13 has been able to support the ability of osmoregulation glass eel to maintain homeostatic condition during the transportation until 3 days of recovery period. There was no drastic decline in physical and chemical value of water in the transport bag so it could reduce the mortality rate for 24 hours.

Adanya kasus pandemi COVID-19 menyebabkan berkurangnya pendapatan masyarakat Desa Pulao Semambu. Hal ini disebabkan oleh dua faktor yaitu pertama terhentinya berbagai agenda wisata yang dilakukan di Desa Pulau Semambu yang berimbas pada tidak adanya wisatawan yang membeli hasil panen, serta kedua, meskipun masyarakat masih tetap dapat menjual hasil pertaniannya di Pasar Indralaya, namun pandemi COVID-19 juga menyebabkan daya beli masyarakat menurun. Kebijakan pemerintah untuk work from home (WFH) berimbas pada tutupnya sebagian besar rumah makan yang berada di dalam dan di sekitar Universitas Sriwijaya, dikarenakan tidak adanya mahasiswa yang aktif hadir secara langsung sehingga kebutuhan akan sayuran dari Desa Pulau Semambu menjadi menurun. Tujuan kegiatan ini adalah memberikan informasi teknologi berupa budidaya ikan dengan memanfaatkan ruang pekarangan yang terbatas berupa Teknik budidaya ikan dalam ember (BUDIKDAMBER) serta pengolahan ikan berbasis zero waste. Kesimpulan dari kegiatan ini adalah tema kegiatan pengabdian tehnik budikdamber dan pengolahan ikan berbasis zero waste diterima dengan baik oleh masyarakat Desa Pulau Semambu, aktivitas diskusi dan tanya jawab yang berlangsung seru dan menarik. Paket bantuan berupa 5 unit budikdamber dan 5 unit hand sealer sangat bermanfaat untuk pemanfaatan teknologi secara langsung dari materi yang disampaikan dan diharapkan dapat memacu masyarakat untuk dapat mengaplikasikan ilmu/teknologi yang diperoleh.
