Abstract

Cantang grouper received more serious attention from grouper fish farmers due to high export interest, but the attack of viral nervous necrosis (VNN) became a major obstacle in its cultivation. This study aims to explore the antiviral potential of diatom Amphora sp. to counter the VNN attack on Cantang groupers. The method used is the extraction of Amphora sp. with absolute methanol solvent. The extraction results were tested in vivo by giving Amphora sp. with different concentrations, namely: 17 µg / ml, 33 μg / ml, 50 μg / ml, and administration of extracts by challenging the 17 μg / ml + VNN, 33 μg / ml + VNN, 50 μg / ml + VNN. Fish treated with Amphora sp. also challenged by giving VNN Positive fish meat. During the period of rearing fish observed clinical behavior and symptoms. After the fish were raised for 15 days, the fish harvested were analyzed using histology, RT-PCR, and CPI methods (using the immuno ratio software) to see the HSP immune response obtained from the administration of Amphora sp. to find out its potential as a natural antivirus. From several test parameters, the concentration of extract 50 mg / ml + VNN was given to give the best response in the CPI analysis with a DAB value (61.3%). These results indicate that the methanol extract of Amphora sp. has the potential to be used as an antiviral candidate in Cantang grouper fish.

Abstract

FCR or feed conversion ratio is one of the strategic indicators on pond production which is very important for determining the costs incurred during the shrimp culture period. The purpose of this study was to examine the relationship between water physico-chemical parameters and the conversion rate of shrimp feed in intensive shrimp ponds (Litopenaeus vannamei). The research method used in this study is the ex-pose facto design during shrimp culture cycle with uniformity of treatment during the cultivation process, then the research collective data obtained periodically is analyzed by multiple linear regression. The results of this study indicate that all pond water quality variables based on quality standards are still in accordance with the standards intended for aquaculture. While based on regression analysis and t-test, the temperature variable is the only parameter that has a direct influence on the FCR efficiency by shrimp. As well as temperature, salinity, and alkalinity variables are parameters that have a close level of relationship to the FCR value in the ponds of 84.1%, 79.1%, and 69.9%. The conclusion of this study is that in intensive ponds the parameters of temperature, salinity, and alkalinity are water quality parameters that have a close relationship with the efficiency of FCR values ​​in ponds, with temperature parameters being the water quality variable which has a direct influence on the effectiveness of the feed conversion ratio by shrimp.
