Physiological response of the blue shrimp Litopenaeus stylirostris to short-term confinement on a pond bottom
Provedor de dados: 5
Autores: Mugnier, Chantal; Lemonnier, Hugues; Legrand, Alexandre.
The blue shrimp Litopenaeus stylirostris was exposed to pond sediment for 48 h and its physiological response was studied in relation to molt stage. Shrimp were maintained in cages within a semi-intensive pond after 4 months of rearing. Hypoosmoregulatory capacity (hypo-OC), magnesium ions (Mg ions), glucose, total proteins and oxyhaemocyanin were assayed in haemolymph. An increase of 370% to 500% in Mg ions concentration and 200% to 266% in glucose concentration, and a decrease in hypo-OC in shrimp maintained close to the centre of the pond indicated a short-term stress response in all molt stages. Indicators of water and sediment pore water quality were within normal operating limits, however this area was characterized by high water content and...

In the booming context of shrimp culture in French Caledonia, some research actions need to be considered in order (i) to make sure this production will not impact the quality and biodiversity of the coastal environment it is contingent upon (ii) for the field to highlight, based on objective bases, its good "environmental image", for an efficient commercialization of its products. In the framework of the MOM project, a number of actions have been carried out: Action 1: A bibliographical synthesis of the impact of shrimp culture on coastal environment has been conducted, taking into account the works carried out throughout the world and in French Caledonia in order to draw the main issues the Territory will have to deal with. It seems necessary to start...
