Aquaculture contributes more than one-third of the animal protein from marine sources worldwide. A significant proportion of aquaculture products are derived from marine protostomes that are commonly referred to as 'marine invertebrates'. Among them, penaeid shrimp (Ecdysozosoa, Arthropoda) and bivalve molluscs (Lophotrochozoa, Mollusca) are economically important. Mass rearing of arthropods an...

Heavy metal pollution in aquatic environments is a critical environmental concern, as the metals can accumulate in aquatic organisms and humans via the food chain, creating a risk to human health. Among the metals, Pb is one of the most toxic to aquatic organisms[1]. Pb is a naturally occurring substance, released as a consequence of geological weathering and volcanic activity, however, high co...

This study investigated the growth inhibition effects of three phenicol antibiotics on microalgae used in aquaculture. Different dose levels of chloramphenicol (CAP), florfenicol (FF), and thiamphenicol (TAP) were added to cultures of one freshwater green alga, Chlorella pyrenoidosa, and two marine algae, Isochrysis galbana and Tetraselmis chui. For the two marine algae, FF showed higher toxici...

Microalgae play indeed a crucial nutritional role with regard to marine animals in the open sea, and consequently in aquaculture. Most marine invertebrates depend on microalgae for their whole life cycle, so commercial and experimental mollusc or fish hatcheries have included a microalga production system in parallel to their animal production itself. Microalgae are utilized as live feed for al...

Ecological modeling of dynamic systems such as marine environments may require detailed spatial resolution when the modeled area is greatly influenced by complex physical circulation. Therefore, the simulation of a marine ecosystem must be underlain by a physical model. However, coupling hydrodynamic and biogeochemical models is not straightforward. This paper presents a modeling technique that...

Marine aquaculture has the potential to increase its contribution global food system and provide valuable ecosystem services, but appropriate planning, licensing regulation systems must be in place enable sustainable development. At present, approaches vary considerably throughout world, several national regional investigations have highlighted need for reforms if marine is fulfil potential. Th...
