“…(27) These preliminary findings have yet to be substantiated with a wider range of immuneassociated and non-related genes, but it is known within shrimp farming that selective breeding can be used to produce shrimp phenotypes better able to withstand specific diseases, such as the Taura syndrome virus. (55) Fundamental mechanistic studies on the genetics of immune traits are now essential to clarify our understanding of the nature of the invertebrate immune system and the role, if any, of inheritance.…”

SummaryRecently claims have been made for radical new insights in the field of invertebrate immunology that involve memory, specificity and/or maternal transfer of immunocompetence. For evidence these claims rely on phenomena, such as survival or reproductive capacity, observed at the level of the whole organism. The allure of these apparently revelatory hypotheses is that they are contrary to established views of innate immunity. They draw implicit analogy to adaptive responses in jawed vertebrates and the terminology used creates an incomplete and misleading picture. We argue that the case for adaptive immunity in invertebrates based only on such phenomena is weak and flawed, as it can only be upheld if supported by descriptions of the underlying mechanisms. We caution against a reliance on this approach as a means of advancing this field-highlighting, as an example, some negative commercial implications of adopting this approach.

“…Among the strategies to reduce the impact of shrimp viral disease has been the development of specific pathogen free and specific pathogen resistant stocks following the discovery of significant differences in susceptibility among different families of shrimp 14,17,18 . However, the effect of host nutritional factors has been less frequently considered.…”

ABSTRACT:To examine the effect of selenium (Se) supplementation on shrimp growth and disease resistance after Taura Syndrome virus (TSV) challenge, groups of Pacific white shrimp (Penaeus vannamei) from a strain known to be susceptible to TSV were fed 3 diets: (1) standard commercial shrimp feed (0.58 ppm Se content) without Se supplementation (standard diet group); (2) standard commercial feed plus 0.3 ppm inorganic Se (Inorg Se-group); and (3) standard commercial feed plus 0.3 ppm organic Se (Org Se-group) over a 5-week period. Samples (3 shrimp) were collected from all replicates before feeding (pre-feeding or week 0) and at the 1st, 2nd, and 3rd weeks post feeding to determine weight, length, and number of granular haemocytes. After the feeding trial, the remaining shrimp were used for a final TSV challenge test. Significant differences in weight between groups (P < 0.05) were found on the fifth week post feeding in which the average weight of shrimp fed the standard feed was 7.2 ± 1.2 g compared to 6.1 ± 1.2 g in the inorg Se-group and 9.0 ± 1.1 g in the org Se-group. Significant increase in the number of total haemocytes and granular haemocytes (GHs) were found only in the org Se-group on the third week post feeding. On day 6 post TSV challenge, the number of survivors in the org Se-group (66.7%) was also significantly higher than those of the inorg Se-(35.5%) and standard diet-(13.3%) group. Nested RT-PCR analysis showed that the number of shrimp with severe infection in the org Se-group (2/5) was less than the inorg Se-(4/5) and standard diet-group (4/4). The RT-PCR results were similar to those observed by histological examination. The number of total haemocytes and GHs isolated from survivors of the standard diet-group were significantly lower than those isolated from survivors of the inorg Se-or org Se-group. The present results indicated that organic Se supplementation in shrimp feed could improve shrimp growth and survival after an experimental challenge with TSV.

“…And as such, several breeding programmes have been going on using natural selection approaches [141][142][143]. The major drawback with this approach is that it takes several generation cycles to identify individuals having positive growth traits.…”

Applications of RNA-Seq and Omics Strategies - From Microorganisms to Human Health

Gene expression studies in aquaculture have slowly evolved from the traditional reductionist approach of single gene sequencing to high throughput sequencing (HTS) techniques able to sequence entire genomes of living organisms. The upcoming of HTS techniques has led to emergence of metagenomics, nutrigenomics, epigenetics and other omics technologies in aquaculture in the last decade. Metagenomics analyses have accelerated the speed at which emerging pathogens are being discovered, thereby contributing to the design of timely disease control strategies in aquaculture. Using metagenomics, it is easy to identify and monitor microbial communities found in diferent ecosystems. In vaccine production, genomic studies are being used to identify cross neutralizing antigens against variant strains of the same pathogens. In genetics and epigenetics, genomics traits have been identiied that are beginning to gain commercial applications in aquaculture. Nutrigenomics have not only enhanced our understanding of the biological markers for nutrition-related diseases, but they have also enhanced our ability to formulate diets able to maintain a stable immune homeostasis in the gut. Overall, herein, we have shown that functional genomics provide multifaceted applications ranging from monitoring microbial communities in aquatic environments to optimizing production systems in aquaculture.
