The rising atmospheric CO2 level is continuously driving the dissolution of more CO2 into the oceans, and some emission scenarios project that the surface waters may reach 1000 ?atm by the end of the century, write Fredrik Jutfelt and Maria Hedgrde, University…
Kassaye Balkew Workagegn, Hawassa University, Ethiopia, conducted this study to investigate the growth performance, feed utilization efficiency and survival rate of juvenile Oreochromis niloticus reared in aquaria at different water temperature.
In part three of three, A.M. Abdelhamid, Mansoura University, Egypt, aims to investigate the effect of dietary graded levels of Aqua Superzyme, Garlen Allicin, and Diamond V (Original XPC) on the chemical composition and histology of all-males mono-sex Nile ti…
Ocean acidification has a variable impact on the growth and survival of marine invertebrates. Larval stages are thought to be particularly vulnerable to environmental stressors, and negative impacts of ocean acidification have been seen on fertilization as wel…
In part two of three, A.M. Abdelhamid, Mansoura University, Egypt, aims to investigate the effect of dietary graded levels of Aqua Superzyme, Garlen Allicin, and Diamond V (Original XPC) on feed utilization by Nile tilapia fish for 16 weeks.
Aquatic farmers face enormous pressure from native and exotic disease-causing organisms, or pathogens. Infection and disease can invade from multiple sourceswater, wild fish or shellfish, newly-introduced farmed fish or shellfish, contaminated equipment, preda…
