Summer mortality is a phenomenon that causes mass die offs of molluscs during the summer months. Summer mortality affected molluscs include many economical important animals including; oysters, mussels, clams, scallops and abalone. The condition occurs in both natural and aquaculture environments...

The oyster Crassostrea gigas is a major, global aquaculture species. As with any domestically-farmed species, the characterization of breeding lines that yield desired phenotypes is of immense value. An understanding of the fundamental biological bases of such phenotypes is needed to enhance ...

Three isonitrogenous diets (41% crude protein) with 4.87%, 10.75% and 16.10% lipid were designed to evaluate the effects of dietary lipid levels growth, antioxidant capacity, expression levels of genes related to lipid and glucose metabolism of juvenile Scylla paramamosain. Each diet was fed to...

An 8 weeks regression study was performed to test the effects of increasing light intensities from darkness to 30 W m^-2 on growth performance, molting, antioxidant capacity, and gene expression of molting and apoptosis-related genes in Scylla paramamosain. No significant differences were found in...

Cyclin B functions as a regulatory protein through association with its catalytic partner Cdc2 kinase forming M-phase promoting factor (MPF), which plays a central role in the meiotic maturation of oocyte. To gain insight into the molecular events, we here cloned a cyclin B cDNA from the ovary of...

This research evaluated the protective effect of vitamin A (VA) on the adverse effect of fish oil (FO) substitution with palm oil (PO) in an economical crab Eriocheir sinensis. Three diets of FO, PO, and PO + 8000 IU/kg VA as the main lipid sources were fed to crabs, respectively, for 8 weeks....

Aquaculture assumes a pivotal role in meeting the escalating global food demand, and shrimp farming, in particular, holds a significant role in the global economy and food security, providing a rich source of nutrients for human consumption. Nonetheless, the industry faces formidable challenges,...

In this special publication (no. 16) of the Aquaculture Association of Canada a review on the project (over 220) descriptions detailing an impressive range of topics, disciplines, and species from across the vast geography of Canada was presented. Projects include marine and freshwater species,...

The Pacific oyster (Crassostrea gigas), as the most productive cultured shellfish in the world, has considerable economic importance and value. Yet research on its sex determination remains lacking. Here, a novel HMG-box-containing homolog of the sox gene was uncovered in C. gigas (named ...

β-1,3-glucans, natural polysaccharide groups, exert immunomodulatory effects to improve the innate response and disease resistance in aquatic species and mammals. However, this β-glucan stimulant is yet to be assayed in swimming crab (Portunus trituberculatus) hemocytes. In this study, we explored...
