The aquaculture industry continues growing worldwide. In the Magdalen Islands seafarming started in the 80 and experienced a significant growth in the last decade in terms of production and added value. According to integrated environmental management and planning, sustainable development in aquaculture can be ensured through a rigorous evaluation of the seafarming potential in the available ar...
The activity of cholinesterase (ChE), glutathione-S transferase (GST), glutathione reductase (GR), glucose-6-phosphate dehydrogenase (G6PDH) and catalase (CAT) was evaluated in the gill and digestive glands of the Perna perna mussel transplanted to three non-contaminated mariculture zones under the influence of distinct physical-chemical characteristics. Differences among sites for ChE, GST and...
Shellfish farming is the most common and the most established activity of aquaculture in France and in EU15. Such as main suppliers of mussels and oysters, mariculture production makes up the referent market for bivalves molluscs, unlike most other aquatic species for which capture fisheries are prevalent. Moreover, the specificity of oyster cultivation is marked with respect to the French posi...
A Sub-littoral mussel reefs harbours rich and diverse invertebrate communities. They utilize the reef complex as their habitat, rich feeding substrate and also as refuge from predation. Though the invertebrate diversity of the reefs is available, reports pertaining to their relation to dietary habit of reef fishes are lacking. A study was taken up at the sub-littoral mussel reefs occurring off ...
This paper innovates as it tests two different hypotheses regarding climate impacts on agricultural markets in Brazil: farmers only observe the average climate conditions of their region when deciding the type and amount of crop/animal to grow/raise; and weather diversions from normal climate conditions deviate farmers from their optimal profits. Both hypotheses are not rejected by the data. Th...
Sea otters (Enhydra lutris) are keystone predators that consume a variety of benthic invertebrates, including the intertidal mussel, Mytilus californianus. By virtue of their competitive dominance, large size, and longevity, M. californianus are ecosystem engineers that form structurally complex beds that provide habitat for diverse invertebrate communities. We investigated whether otters affec...
