Apu wood is a living aquatic plant floating in a lentic water and has a good nutrient content. This study aims to find out the nutrient content of fermented apu wood and evaluate the effect of substitution of soybean flour with fermented apu wood meal in feed on the performance of red tilapia. The study used a randomized design method complete with four substitution treatments of soybean meal with fermented apu wood of 0, 10, 20, and 30% with three repeats. The study used red tilapia measuring 7-9 cm to feed a dose of 3% biomass with a frequency of giving twice a day and maintained for 60 days. Parameters evaluated include sintasan, growth, feed conversion rate, protein efficiency ratio, and feed efficiency. The results of the fermented wood meal proxy test contained water content of 8.80%, protein by 15.10%, fat by 3.12%, ash content by 34.5%, and fiber by 33.96%. Fermented apu wood meal cannot substitute soybean meal as a feed material. Substitution of soybean meal with fermented apu wood meal in feed does not affect the intensity, feed efficiency and protein efficiency ratio but has an effect on decreasing growth performance and increasing the value of feed conversion rate.

Acartia sp is a zooplankton that has the potential to be developed and used as naturalfeed for marine fish larvae. The problem in cultivation is that the right feed is neededas a support for the growth of Acartia sp so that maximum production and feed needsfrom larvae are fulfilled. This study aims to find out the growth response of Acartia sp to the application of egg yolks, pellets and yeast as a source of nutrition. Researchparameters include abundance levels, population peaks, growth rates and waterquality on Acartia sp maintenance. The research method is an experimental laboratorywith 4 (four) treatment levels and 3 (three) repeats. The treatment standards are A:Pellets, B:Egg yolks, C: Yeast (yeast), and D: Nannochloropsis sp (control). Theresearch phase consists of preparation of Acartia sp feed (egg yolk, pellet, yeast, andNannochloropsis sp), feeding, and maintenance of Acartia sp. The results showed thatacculturation of Acartia sp with feed differences affected daily abundance, populationpeak, and growth rate of Acartia sp with the best treatment indicated byNannocloropsis sp (control). The peak population of Acartia sp reached 633.33 ind /L, the growth rate of Acartia sp reached 106.6 ind / day. However, the provision ofpellets becomes an alternative to Acartia sp feed that has the potential to support itsgrowth. The value of water quality parameters during the study is still optimal, namelytemperature 25-27 °C, salinity 33-35 ppt, pH 7.1-7.9, DO 4.9-6.6 mg / L, and ammonia0.087-0.284 ppm.

Lemna has a fairly good protein content. The use of Lemna as a fish feed material is experiencing obstacles such as materials derived from plants in general, namely low protein levels and high levels of fiber. This study aims to find out the nutrient content of fermented Lemna meal and the effect of fermented Lemna meal on the growth of red indigo (Oreochromis sp.). The study used the Complete Randomized Design Method with four dose treatments: P0 (0%), P1 (10%), P2 (20%), and P3 (30%) with three repeats. The study used red tilapia measuring 7-9 cm and was maintained for 60 days. Feed is given as much as 3% of fish biomass with the frequency of feeding twice a day. Fermented Lemna meal has a water content of 4.45±0.07%, protein by 13.67±0.08%, fat by 4.24±0.81%, ash by 26.9±0.14%, fiber by 32.53±0.29%, and carbohydrates by 50.74±0.81%. Fermentation can increase protein levels from Lemna. Substitution of soybean meal with fermented Lemna meal has not been able to provide good growth than P0 (0%), but the substitution of 10% addition has no effect on FCR and feed effisiency of red tilapia.

Artemia is the main feed in botia seeds up to three months of age so artemia substitution is essential for efficient maintenance. The study aimed to determine tubifex frequency ratio to substitute Artemia in botia seeds. The botia seeds used are one month old with a weight of 35-90 mg and a length of 13-20 mm are maintained in the recirculation system for eight weeks to three months of age. The study design is a complete randomized design (RAL) factor of two factors, namely the first factor is the class of fish size S (35-54 mg), M (55-74 mg), L (75-94 mg) and the second factor in the form of five ratios of artemia substitution frequency: Tubifex from A (4:0) which is 4 times a day for Artemia and 0 times a day for Tubifex, B (3:1), C (2:2), D (1:3) and E (0:4). Fifteen interaction treatments result from both factors namely SA (size S; frequency ratio A), SB, SC, SD, SE, MA, MB, MC, MD, ME, LA, LB, LC, LD, and LE repeated twice. Observations are made by measuring growth i.e. weight, total length, and sintasan. Data analyzed statistics followed by the Tukey test. The results showed that Tubifex can be given as many as 4 times per day across all fish size classes without artemia.

Tilapia is one of the types of freshwater fish that have a high economic value. One of the problems in cultivation activities is the price of raw materials feed that is relatively expensive. To overcome this, the use of seaweed meal can be one of the alternative ingredients in reducing the use of fish flour and soy flour in feed. The purpose of this study was to analyze the effect of the addition of E. cottonii seaweed meal on feed on the growth and survival of tilapia (O. niloticus). The research method used is an experimental method using a complete randomized design (RAL), with 4 treatments and 3 repeats. The treatment in this study was P1 (control / no seaweed meal), P2 (E. cottonii meal 4%), P3 (E. cottonii meal 8%), P4 (E. cottonii meal 12%). Data is analyzed using diversity fingerprint analysis (ANOVA) with a 95% confidence level. The results showed that the addition of E. cottonii seaweed meal to feed had a significant effect on absolute weight growth and absolute long growth in tilapia, but did not have a significant effect on specific growth rates, efficiency of feed utilization, feed conversion rate and tilapia survival.

Vannamei shrimp cultivation has been carried out for quite a long time in Indonesia, the more advanced the era of vannamei shrimp cultivation techniques have developed very rapidly. The main goal of technological developments for vannamei shrimp is a high level of production. The vannamei shrimp culture system with the bioflox method can be interpreted as living organic matter that blends into lumps. The clumps consist of various aquatic microorganisms including bacteria, algae, fungi, protozoa, metazoa, rotifers, nematodes, gastrotricha and other organisms suspended with detritus so that the flocs in shrimp can be used for feed. While the Running water system is the movement of water needed to keep the particles in suspension. If biofloc particles settle, anaerobic slurry pockets often form which can release ammonia or sulfides; sulfide can be directly toxic to animals and can inhibit nitrification, thereby leading to a further increase in toxic nitrogen compounds. For Recirculation Aquaculture system is a shrimp rearing system using the recirculation method without any water change where the wastewater is managed with several filters. The RWS (running water system) system has the advantage that the movement of the water system makes it easier to collect nutrients so they are easy to dispose of and control. The second advantage of the process is that it facilitates nitrification and with a stocking density of 750,000 m2, initial weight of 3.2 grams, final weight of 11.4 grams, daily weight of g/day 0.745, total feed 7450 and survival rate of 85%, food conversion ratio 1.11

Carp (Cyprinus carpio) is one type of consumption fish which is a freshwater fishery commodity that has good prospects. The purpose of this study was to analyze the effect of using young Moringa leaf flour (Moringa oleifera) as raw material for artificial feed on carp (Cyprinus carpio) cultivation. The research method used was a completely randomized design (CRD) consisting of 4 treatments and 3 replications, treatment P1 (control), P2 (10% Moringa leaf flour), P3 (20% Moringa leaf flour), P4 (30% Moringa leaf flour). moringa). The results showed that the addition of Moringa leaf powder to feed with different doses could affect absolute weight, FCR, EPP and survival of carp (Cyprinus carpio) but did not affect absolute length and specific growth rate. The addition of 30% Moringa leaf flour to carp feed is the best treatment, because it can provide an absolute weight of 5.09 g, FCR of 1.86%, EPP of 53.95% and SR of 86.67% in carp culture.

Gouramy (Oshpronemus gouramy Lac. 1801) is a native Indonesian fish that has a high market with relatively expensive prices. One of the obstacles commonly faced in the cultivation of gouramy is its slow growth. Silkworm (Tubifex sp.) is a type of natural feed with a high protein to support the accelerated growth of gouramy. The purpose of this study was to determine the absolute weight growth and survival of gouramy with different doses of silkworms. This study used a completely randomized design with 4 treatments and 5 replications. Giving silkworms in Treatment 1 (P1) was 10%, Treatment 2 (P2) 15%, Treatment 3 (P3) 20% and Treatment 4 (P4) 25% of the weight of the biomass. The results of the analysis of variance (ANOVA) showed that silkworm with different doses has significantly different results (P<0.05) on absolute weight growth of gouramy. Then, treatment 4 showed the highest absolute weight growth of 0.0444 g. Meanwhile, the survival of gouramy showed results that were not significantly different (P>0.05).
