Abstract

The relationship between nuclear and plasma in aquaculture businesses as one of several agricultural businesses were observed in two regions, i.e., Lampung and West Java. CP Bahari and Triasta Citarate Ltd. were used as a sample of this relationship. The results showed that the education level of aqua-culturist was 80% senior high school and 20% secondary school. CP Bahari (nuclear) had already fulfilled the duties to the plasma aqua-culturist. However, cooperation (Bima Utama) as a channelling agent did not work properly. There was not self-help group; the only group was a neighborhood from which the company controlled aqua-culturist. Extension from Fisheries Agency Office was not properly done. Local government autonomy resulted in too many tax regulations from which overlapping taxes had been happened. Aqua-culturist cooperation (KUD) did not work as in agreement with Central Bank of Indonesia. The information of plasma credit was not clear as well as the balance position of their money. In Triasta Citarate, the existing of KUD was just to speed up the process of money transfer to the nuclear.

Abstract

The aim of the study was to investigate the effect of different types of carbohydrates on growth, survival, feed efficiency and fish production (Pangasius pangasius), in the biofloc system with zero-water exchange. Added carbohydrates were tapioca, molasses, bran and cornstarch which were set at level of 25% of the theoretical adding quantity. A total of 6000 fish larvae used in this experiments. Complete Randomized Designed was used with four treatments and three replications. Twelve tanks used in which each tank was a cylinder tank (1814.92 L) and each tank contained 500 fish. The results showed that the concentrations of ammonia and nitrite differ significantly in the experimental tank added maize when compared to other carbohydrate sources. The nitrate levels showed that highly concentration was observed in the maize treatments compare to tapioca and molasses treatments, however it was not significantly different than that of rice bran treatments. The floc volume stabilized after about 3 weeks in the BFT tanks. Different carbon sources had resulted in different proximate composition tendencies. The highest yield obtained in molasses treatments which were highest compare to all carbohydrate treatments, whilst tapioca, rice bran, and maize treatments were not significantly different

Abstract

Osteochilus vittatus is a freshwater fish that needs to be developed because it tastes savory and can be used as a biocleaning agent. Research on the effect of supplementation of Spirulina platensis in nilem fish that is maintained in a biofloc system on digestive enzyme activity has never been done before. The objectives of this study were to determine the effect of S. platensis supplementation on Osteochilus vittatus digestive enzyme activity maintained in the biofloc system and to obtain the most optimum level of S. platensis supplementation in improving the  digestive enzymes activity. The study was conducted experimentally with Completely Randomized Design with four treatments and five replications. Osteochilus vittatus were fed with Spirulina platensis level of 0, 2, 4, and 6 g kg-1 for 56 days. Enzyme activity was measured on days 0 and 56 with three kinds of buffer solutions. Amylase and protease activity was analyzed using ANOVA with a confidence level of 95%. The results showed that the highest amylase activity in the liver was 4.764 ± 1.705 U mg-1 protein and proximal intestine was 2.328 ± 0.838 U mg-1 protein. The highest protease activity was found in the liver and proximal intestine with activity of 6.536 ± 0.911 U mg-1 protein and 6.207 ± 2.195 U mg-1protein. Spirulina platensis supplementation level of 6 g kg-1 feed is the most optimum level (p<0.05). Cultivation of fish with S. platensis supplementation in feed can increase enzyme activity and the fish maintenance in biofloc systems can improve water quality.

Abstract

Spirulina platensis is a microalgae that contains nutrients such us iron and phycocianin higher than other microalgae. Research on suplementation of S. platensis in Osteochilus vittatus cultured in biofloc system has never been done. The aim of this study was to determine the blood hematological and biochemical parameters of O. vittatus fed with S. platensis supplementation and maintained in biofloc system. The study was conducted experimentally with Completely Randomized Design, four treatments and five replications. O. vittatus were fed with S. platensis level 0, 2, 4, and 6 g.kg-1 for 56 days. Blood hematological and biochemical parameters were measured on days 0 and 56. Values of those parameters were then analyzed using ANOVA with a confidence level of 95%. The result showed that the highest red blood cells, white blood cells, and hemoglobin counts were 1.57x106­­­­ cell.mm-3, 2.37x105 cell.mm-3, and 6.77 g.dl-1 respectivley, while the highest hematocrit value was 17.5 %. The highest total protein, albumin, and globulin in blood were 7.96 g.dL-1, 4.31 g.dL-1, and 3.79 g.dL-1 respectively, and the best for ratio A/G was 1.14. S. platensis suplementation level of 4g.kg-1 feed was the most optimum level (P<0.05). Cultivation of fish with S. platensis supplementation in feed can increase fish health indicated by the hematological and biochemical parameters of the blood and the fish maintenance in biofloc systems can improve water quality. The benefit of this research is to make a good condition for cultivation and efficiently used not only water but also feed.
