In this paper we present the reactive extrusion process to extract the phycocolloids from the sea products. By comparing with other techniques, this process has a several advantages like the economic return, the flexibility, the production of various products with different characteristics and time gains. There are two types of extruder: single-screw and double-screw, each one has its specific properties. The solid products are introduced by means of the hopper that is equipped with a dosage pump for the regulation of the flow. Liquid products are, generally, injected in the not filled zones, through an external pump. The products undergo thermo mechanical modifications and then the shaping of the final products was done in the die. The reactive extrusion...

Whatever the hydraulic gestion, an épuration of the fishes sewages is possible with the integrated system studied. The main action is situed in the intermediary pond with a significant decrease of nutrients, especially ammonia, and particulate mineral matters. The oyster's pond have no significant action on nutrients, but their action is real on chlorophyll which become limiting factor in 20% renewal system. One of the effluent, system 1 (renewal 10%) had high suspended matter and low nutrient concentrations. The other (renewal 20%) was poor in supcnded matters (chlorophyll). The system 2 give best oyster's growth, close to traditional nursery performances, with an highest mortality (32%). In the first system, suspended matter concentrations are too high...

Valorisation de la pêche artisanale de Saint Pierre et Miquelon : potentialités du marché local
Provedor de dados: 5
Autores: Dewals, Jean-françois.
This thesis is part of the ATLANTILES program, which seeks to study the interactions between small-scale fishing, the historic sector of the archipelago of Saint-Pierre and Miquelon (SPM), and tourism, emerging sector. This work explores the ways in which seafood products from artisanal PMS fishing can be exploited on the local market. For this, it is organized in several parts. The first part presents the socio-demographic context of the archipelago and its influence on the local fishing sector. It highlights the important impact of COM status and the geographical position of the territory on the MPS fisheries sector. The second part of the paper introduces the characteristics of the local artisanal fishery and attempts to understand its interactions with...
