Shrimp Cultivation

Purworejo Regency is one of the centers of pacific white shrimp cultivation in Indonesia. One of the sub-districts in Purworejo Regency which successfully cultivates the pacific white shrimp is Grabag Sub District, who won the first place of shrimp cultivation competition in organization and institution performace assessment category for Central Java Province level and national first place winner in shrimp cultivation category. This research was located in the sub district of Grabag, Purworejo regency on October 2017-December 2017. The aims of this research are to determine the effect of human capital on the GAP implementation by the farmers and the effect of the GAP implementation on pacific white shrimp productivity. The number of respondents in this research was 75 farmers which were chosen by purposive sampling. This research used regression analysis with Two Stage Least Square model. The results of this research showed that (1) The GAP implementation was influenced by the level of education and farmers’ experiences, while there was no any effect influenced by the age on the GAP implementation, and (2) The GAP implementation of pacific white shrimp cultivation did not affect the pacific white shrimp productivity. However, the GAP implementation did not contradict the productivity. The environmentally friendly GAP implementation and quality oriented did not contradict the productivity of shrimp. Farmers still can implement the GAP without decreasing their productivity.

Electron Microscopes

Fourteen specimens of the hepatopancreas of the Pacific white shrimp, Penaeus vannamei, were prepared for examination with the transmission and scanning electron microscopes and with the light microscope. The histology and ultrastructure of this organ is similar to that seen in other Decapoda. At the ultrastructural level, it was observed that B-cells rupture at approximately the level of gap junctions located on the lateral plasma membranes of the cells, and discharge the contents of their large vacuoles into the intercellular space. This efflux of enzymatic material may be the mechanism by which cells are released from the wall of the tubule at the proximal end: the rupture and collapse of a B-cell may be analagous to the removal of the keystone which supports an arch. Deprived of support, and lacking structural adaptations for cohesion (there are no desmosomes or interdigitations in the epithelium) and with the intercellular material digested, the remaining intact cells collapse into the lumen of the tubule. The lysis of individual cells of all types - R-, F-, and B-cells - may contribute to the tubules’ total complement of digestive enzymes.

Clustering Approach

Aquaculture production of the Pacific white shrimp is the largest in the world for crustacean species. Crucial to the sustainable global production of this important seafood species is a fundamental understanding of the shrimp gut microbiota and its relationship to the microbial ecology of shrimp pond. This is especially true, given the recently recognized role of beneficial microbes in promoting shrimp nutrient intake and in conferring resistance against pathogens. Unfortunately, aquaculture-related microbiome studies are scarce in Southeast Asia countries despite the severe impact of early mortality syndrome outbreaks on shrimp production in the region. In this study, we employed the 16S rRNA amplicon (V3–V4 region) sequencing and amplicon sequence variants (ASV) method to investigate the microbial diversity of shrimp guts and pond water samples collected from aquaculture farms located in Malaysia and Vietnam. Substantial differences in the pond microbiota were observed between countries with the presence and absence of several taxa extending to the family level. Microbial diversity of the shrimp gut was found to be generally lower than that of the pond environments with a few ubiquitous genera representing a majority of the shrimp gut microbial diversity such as Vibrio and Photobacterium, indicating host-specific selection of microbial species. Given the high sequence conservation of the 16S rRNA gene, we assessed its veracity at distinguishing Vibrio species based on nucleotide alignment against type strain reference sequences and demonstrated the utility of ASV approach in uncovering a wider diversity of Vibrio species compared to the conventional OTU clustering approach.
