Litopenaeus vannamei is a leading commodity whose economic value. Targets of vannamei’s production increasing every year. One of important factor in the success of shrimp farming is feed. Research about feed fish directed to the creation of feed fish whose economical and safe for the environment, therefore is required an efforts to provide alternative feed through feed supplement. One of the material that can be supplemented in feed is chitosan. Chitosan can increase the specific growth rate and protein retention of vannamei. This study aims to determine the effect of chitosan supplementation in commercial feed for specific growth rate and protein retention of Litopenaeus vannamei. The research method used was completely randomized design (RAL) and performed with five treatments chitosan supplementation (0%, 1%, 2%, 3% dan 4%) experimental animal used was ten shrimps as five replication in each treatment. The main parameters were observed are specific growth rate and protein retention of vaname. Supporting parameters were observed is water quality. The results showed that chitosan supplementation in commercial feed for 30 days of maintenance give an effect on the specific growth rate and protein retention of vaname. The highest specific growth rate was obtained in treatment with 4% chitosan supplementation that not significantly different with treatment 3% chitosan supplementation. Protein retention was incresed in treatment with 4% chitosan supplementation that not significantly different with treatment 3% chitosan supplementation.

The purpose of this study was to determine the addition of probiotics in commercial feed to the growth and survival of Asang fish (Osteochilus vittatus CV) fry. This study used an experimental method with a completely randomized design (CRD) with 4 treatments and 3 replications. The test fish used were 120 fish with a size ranging from 5-8 cm. The test fish were kept in a waring cage made of a type of paralon frame with a size of 40 x 40 x 45 cm. The treatment in this study was A (without probiotics), treatment B (addition of probiotic 10 ml/kg of feed), treatment C (addition of probiotic 20 ml/kg of feed), and treatment D (addition of probiotics 30 ml/kg of feed). From the results of this study, the highest specific growth rate was found in treatment D (6.66 ± 1.15 g), while the mean survival was 100% for all treatments. The highest FCR of fish fry was found in treatment A namely 1.43 ± 0.22, and the lowest in treatment D namely 1.12 ± 0.21, and for feed efficiency in treatment D, namely 95.24 ± 1.04 %.Keywords:Asang fishEfficiencyGrowthSurvival

This research was conducted to determine the effect of giving different lime on the survival rate and growth of snack head seeds. This writing uses a completely randomized design (CRD) with 4 treatments and 3 replications. The hypothesis being tested was that the application of the limed lime had no significant effect on survival rate, the growth of snack head seed and the specific growth rate and lime administration differed significantly in feed conversion. The study was conducted at the Wet Aquaculture Laboratory, Palangka Raya University starting from February 3 - March 3, 2020. The results showed that the administration of different lime had no significant effect on survival rate, growth and specific growth rates but had a significant effect on feed conversion. The best survival rate of snack head seeds is in treatment D (250 g) that is equal to 57.73%, the best weight growth is in treatment C (200 G) that is equal to 3.16 grams, the best length growth is in treatment D (250 g) that is 2.57 cm, the best specific growth rate is in treatment D (250 g) which is 2.92% / day, and the best feed conversion value is in treatment D (250 g) which is 1.47%. Water quality such as temperature, acidity (pH) and dissolved oxygen (DO) are still in the normal range.

Intensification of white shrimp (L. vannamei) cultivation causes accumulation of waste aquaculture in the water and environmental stress which causes pathogenic organisms to develop and attack aquaculture organisms, so that mass deaths occur. Various efforts have been made to overcome this through feed production by adding ingredient that can enhance the body's immune system, but also function as growth promoters. The material that has both functions is seaweed Sargassum sp. The aims of this study was to determine the addition effect of sargassum extract from enzymatic extraction on feed to the specific growth rate/SGR and feed convertion ratio/FCR of white shrimp (L. vannamei). These study was conducted by experimental method used a completely randomized design (CRD) with 3 treatments and 2 repetitions. The treatment was namely A (feed with the addition of sargassum extract 0 g/kg feed), B (feed with the addition of enzymatically protease sargassum extract 2 g/kg feed) and C (feed with the addition of enzymatically carbohydrase sargassum extract 2 g/kg feed). The results showed that the feed with the addition of sargassum extract from enzymatic extraction had a significant effect (P<0,05) on specific growth rate (SGR) and feed conversion ratio (FCR). Water quality of media is in the proper range for shrimp farming.

This study aims to determine the effect of the dose of fermented rice bran using Lactobacillus sp. on growth performance and enzyme activity in tilapia. This research was conducted in Sidenreng Rappang Regency. The test animal used was tilapia larvae measuring 1.17 g. The maintenance container is a tarp pool with a size of 1 m x 1 m x 1 m filled with fresh water as much as 85 L. The study was designed using a completely randomized design consisting of four treatments and three replications, thus there were 12 experimental units. The treatment was determined based on the dose of fermented rice bran using Lactobacillus sp. which differ, namely 0, 10, 15 and 20%. The test feed was given to tilapia larvae, which were stocked with 20 fish per container for 60 days of rearing. The specific growth rate data of tilapia were analysed using analysis of variance (ANOVA) and enzyme activity was analysed descriptively based on the viability of tilapia. The results showed that tilapia fed with 20% fermented rice bran had a significant effect on the specific growth rate, protease and amylase enzyme activity. The optimal dosage of fermented rice bran using Lactobacillus sp. is 15-20%.

The objective of this work was to evaluate the effect of sustained swimming and dietary protein levels on growth and hematological responses of juvenile pacu (Piaractus mesopotamicus). A completely randomized design was used in a 3x2 factorial arrangement, with three levels of dietary protein (24, 28, and 32% crude protein), two rearing conditions (sustained swimming or motionless water), and 15 replicates. Fish were subjected to sustained swimming at the velocity of two body lengths per second (2 BL s-1), for 45 days. The level of dietary protein and the swimming conditions affected the performance, growth, and hematological profile of pacu. Swimming conditions influenced nutritional factors, increasing daily weight gain, specific growth rate, number of erythrocytes, mean corpuscular volume, and mean corpuscular hemoglobin. Fish under sustained swimming and fed with 24% crude protein showed better growth performance, with higher specific growth rate (4.11±0.88) and higher daily weight gain (2.19±0.47 g per day). Sustained swimming can increase the productive performance of pacu and simultaneously reduce dietary protein levels.
