Marine cultivation technology opening the door to the rich sources of clean energy in our oceans
Despite the growing demand and supply of renewable energy sources, we still rely on fossil fuels for much of our global energy. But deep below the ocean, there is a source of clean carbon energy waiting to be harvested, which will go a long way to reducing our dependence on oil, gas and coal – seaweed. A recent study in Nature Geoscience estimated that seaweed floating down to the depths ...

Predicting the effects of copper on local population decline of two marine organisms, cobia fish and whiteleg shrimp, based on avoidance response
Fry of the marine fish Rachycentron canadum (cobia) and larvae of the estuarine shrimp Litopenaeus vannamei (whiteleg shrimp) were exposed to a copper gradient which ranged from 0.20 to 1.80 mg Cu/L for the experiments with cobia and from 0.10 to 1.0 mg Cu/L for the experiments with whiteleg shrimp. The experiments focused on the avoidance response to predict the population decline. Avoidance ...
