Initial larval feeding began with sole rotifers as a live food from 3 to 7 days post hatch (DPH) followed by the addition of copepod, Artemia, and their combination from 8 to 21 DPH. Fish were sampled every 5 days to measure gr ...

Abstract:
... Tetraploids are crucial important for commercial production of all‐triploid Crassostrea hongkongensis. Successful production of tetraploid C. hongkongensis requires precise control of fertilization and applying treatment. The germinal vesicle breakdown (GVBD) ratio of stripped eggs before fertilization influences the efficiency of tetraploid inductions. According to our research, in both diploids ...

Abstract:
... Recirculating aquaculture systems (RAS) are becoming important for aquaculture due to land and water supply limitations and due to their low environmental impact. Bacteria are important in RAS as their role in nutrient recycling has been the main mechanism for waste removal in these systems. Besides bacteria, the presence of microalgae can benefit the water quality through the absorption of inorga ...

The role of Dscam in immune system responses has been established in fruit fly, mosquito, shrimp, crab, and crayfish, among other arthropods. In molluscs, this gene has not yet been clearly identified, and more importantly, its function h ...
