Changing in photoperiod duration may affects the physiology of nocturnal fish such as Pangasianodon hypophthalmus. A study aims to understand the effects of controlled photoperiod towards survival and growth of P. hypophthalmus has been conducted from June to August 2020. There were 3 treatments applied, namely natural photoperiod, 18 hours dark (18D), and 24 hours dark (24D) with 3 replications in each treatment. The rearing tanks used in this study were 100 L circular plastic tanks.  In 24D treatment, the tanks were placed under dark colored tarp tent continuously.  For the 18D treatment, the tanks were placed under dark tarp tent, but the tent was opened for 6 hours/ day (the tanks were in dark condition for 18 hours/ day), while the control tanks were positioned under natural photoperiod. P. hypophthalmus fingerlings, 6-8 cm TL and   4-5 g BW were used in this study. Thirty fishes were reared in each rearing tank, they were feed with commercial pellets, 2 times/day, at satiation. Fish survival was monitored every day, while samplings for fish growth were conducted weekly for a 8 weeks period. Results indicate that the survival of   fish was 100% in each treatment applied. Fish growth, however, shown differences. The growth of fish reared in 24D and 18D was better than that of the control. By the 9th week,  the fish in 24D was around 70.71g BW with 19.27 cm TL  (daily growth rate 9.35%), while those of the 18D was 69.41 g BW, 18.77 cm TL and 9.29% daily growth rate. The fish reared under natural photoperiod was around 61.95 g BW with 18.19 cm TL and 7.33% of daily growth rate. Data obtained indicate that the application of longer dark is positively improve the growth of P. hypophthalmus.Keywords:Nocturnal FishLight Dark Catfish

Masalah utama yang umum terjadi pada produksi benih abalon adalah kematian yang tinggi (> 90%) setelah abalon menempel pada plate pemeliharaan. Penggunaan pakan dalam bentuk tepung untuk mengganti diatom sebagai pakan postlarva beberapa spesies ikan, udang, dan abalon sudah dilakukan. Penelitian ini bertujuan untuk mendapatkan jenis pakan dalam bentuk tepung yang sesuai dan efektif untuk mendukung sintasan dan pertumbuhan larva abalon Haliotis squamata. Percobaan terdiri atas lima perlakuan pakan pada pemeliharaan larva abalon yaitu tepung Spirulina sp., Ulva sp., Chaetoceros sp., Gracilaria sp., dan diatom (kontrol). Masing-masing perlakuan terdiri atas empat ulangan. Pakan berupa tepung yang digunakan pada masing-masing perlakuan, terlebih dahulu dicampur merata dengan larutan tepung agar (7,5 mg/mL dalam air laut; suhu 40°C) dengan konsentrasi tepung 40 mg/mL larutan agar. Pemberian pakan dilakukan setiap tiga hari dengan cara menyemprotkan larutan pakan pada permukaan plate pemeliharaan larva. Penelitian dilakukan selama 30 hari. Hasil penelitian menunjukkan bahwa sintasan larva abalon yang diberi pakan tepung Spirulina sp. paling tinggi dan berbeda nyata (P<0,05) dengan yang diberi diatom, tepung Chaetoceros sp., dan Ulva sp., yaitu masing-masing 81,49%; 79,25%; 76,57%; dan 76,46%; tetapi tidak berbeda nyata dengan yang diberi pakan tepung Gracilaria sp. 81,37% (P>0,05). Laju pertumbuhan harian panjang cangkang larva abalon tertinggi diperoleh pada larva yang diberi pakan tepung Gracilaria sp. (203,81 ± 1,23 µm/hari) dan Spirulina sp. (205,59 ± 1,71 µm/hari). Nilai laju pertumbuhan harian panjang cangkang larva abalon yang paling rendah dijumpai pada larva yang diberi pakan tepung Ulva sp. (146,07 ± 1,73 µm/hari).The most common problem in abalone seed production is the high mortality occurrence (> 90%) after postlarvae settlement to the rearing plates. The use of microparticle diets to replace the natural feed of postlarval has been performed on various species of fish, shrimp, and abalone. This research aims to determine the most effective and suitable powder-based feed to support the survival and growth of abalone Haliotis squamata larvae. The experiments consisted of five feed treatments, i.e., Spirulina sp., Ulva sp., Chaetoceros sp., and Gracilaria sp. Flour, and diatoms (as control). Each treatment had four replicates. The powder-based feed used in each treatment was firstly mixed with a solution of agar powder (7.5 mg/mL sea water, 40°C) with a concentration of 40 mg of flour/mL of agar solution. Feeding was done every three days by spraying the feed solution onto the surface of the larval rearing plate. The study was conducted for 30 days. The results showed that survival rate of abalone larvae fed with Spirulina sp. flour was the highest and significantly different (P<0.05) compared with those given diatoms, Chaetoceros sp. and Ulva sp. flours, which were 81.49%, 79.25%, 76.57%, and 76.46%, respectively, and not significantly different from those fed with Gracilaria sp. 81.37% (P>0.05). The highest daily growth rate of the shell length of abalone larvae was achieved by larvae fed with Gracilaria sp. (203.81 ± 1.23 ¼m/day) and Spirulina sp. flours (205.47 ± 1.71 µm/day). The lowest daily growth rate of shell length was found on abalone larvae fed with Ulva sp. flour (146.07 ± 1.73 µm/day).

The article describes the process of tench growing (male and female species removed from set gear in the Volga river in the Astrakhan region) using experimental feedstuff "T", taking into account the fact that problems with artificial growing tench ( Тinca tinca ) appear first in the process of feeding when wild sires change to artificial food. The research took place on the base of the department of aquaculture and water bioresources of Astrakhan State Technical University in innovation centre "Bioaquapark - scientific and technical centre of aquaculture" in 2015. Special feed including components of animal origin - mosquito grab and sludge worm as an effective substitute to fish flour, as well as components of vegetable origin (carrot, parsley, pumpkin, wheatgrass) for domestication of tenches are offered for the first time. Food technology has been described. The exact composition of the formula, which is being licensed at the moment, is not disclosed. Feed "T", which has undergone biological analysis and is in accordance with organoleptic and physical standards was used for feeding tench female and male species during domestication period (60 days), along with food "Coppens" (Holland). Feed efficiency was determined according to survival and daily fish growth. Growth rate of females appeared more intensive than growth rate of males fed with experimental food "T". Daily growth changed depending on the types of food: from 0.3 ("Coppens") to 0.47 (experimental food) in females, from 0.25 ("Coppens") to 0.39 (experimental food) with males. Ability to survive among tench species fed with "Coppens" and experimental food made 60% and 100%, correspondingly. Nutricion of tench species with experimental food encouraged their domestication, which allowed using tench species in further fish breeding process in order to get offspring. The project was supported by the Innovation Promotion Fund in terms of the project "Development and implementation of the technique for the steady development of aquaculture: food "TechSA".
