Abstract Lakes, rivers and oceans provide unique resources support fisheries aquaculture worldwide. The sector of Kenya contributes approximately 0.8% to the country’s GDP. Marine production is about 9 000 tonnes per year. finfish form bulk marine production, while shellfish (e.g. prawns, lobsters crabs), molluscs octopi squids) are underexploited. Fishery has potential USD 5 billion for Blue E...

Ocean acidification is predicted to impair marine calcifiers' abilities produce shells and skeletons. We conducted laboratory experiments investigating the impacts of CO2-induced ocean (pCO2 = 478–519, 734–835, 8,980–9,567; Ωcalcite 7.3–5.7, 5.6–4.3, 0.6–0.7) on calcification rates two estuarine calcifiers involved in a classic predator-prey model system: adult Panopeus herbstii (Atlantic mud c...

Chymotrypsin is one of the serine proteases families that have various biological functions. A chymotrypsin gene was isolated from hepatopancreas of the mud crab, Scylla paramamosain (designated SpCHY) in this study. The full-length cDNA of SpCHY contained 942 nucleotides with a polyadenylation sequence and encoded a peptide of 270 amino acids with a signal peptide of 17 amino acids. The SpCHY ...

This study attempts to observe and record early embryonic developments of the orange mud crab, Scylla olivacea. The period taken by the eggs to hatch was 8 days and the colour of the eggs gradually changed from yellow to brown, gray and dark gray. During the embryonic development, the developing embryos reached the blastula stage within 24 hours with a mean egg diameter of 329.91 µm ± 6.62. The...
