    New Technologies in Extrusion Process for Shrimp Feed por Muñoz, Osvaldo

    Publicado 2011
    “…In addition a limited availability of water for the sustainable farming of shrimp, has routed this business to intensive raise where the levels of pollution play a very important role. This is why the feed must also generate lower levels of waste.It is well known that the extrusion process compared with the pelleting process, produce better nutritional quality feed, but in the particular case of shrimp, where a feed of high density and stable in the water is required, the extrusion by itself is not able to achieve these levels of desired density.The main characteristics of the shrimp feed are:- Water Stability, Digestibility, Quick sinking, Smaller size of the pellet, Reduces pollution in the water, - Lowering costs in the feed and OtherAlthough the extrusion process requires a highest investment and also the operational costs are higher than the pelleting process, if the extrusion process has the appropriate technology for densification, it would be much cheaper with a much greater profit than the pelleting process and most importantly, with a better quality feed as a result.In this work we show the latest technological advances in this direction to achieve a feed for shrimp in high quality and low cost through the extrusion process.…”

    Lipid Nutrition Research for the Development of Practical Commercial Diets for Corvina and Alternative Ingredients for Aquafeeds por González-Félix, Mayra L., Perez-Velázquez, Martin, Bringas-Alvarado, Lorena, Navarro-García, Gerardo

    Publicado 2015
    “…Aquafeeds for carnivorous fish, like sciaenids, typically contain high levels of fish meal and fish oil, but the high prices of these dietary ingredients, well above $2000.00 US dollars per ton (aqua grades) in January of 2015, makes the use of high inclusion levels unprofitable and unacceptable. …”

    Nutritional role of the natural productivity and formulated feed in semi-intensive shrimp farming as indicated by natural stable isotopes por Gamboa Delgado, Julián

    Publicado 2014
    “…As in the natural ecosystems, these dietary components exhibit differing isotopic signatures at natural abundance levels and since these natural communities belong to different trophic positions and isotopic values of organisms tend to increase with trophic level, the isotopic differences can be measured and used to infer on the transfer of nutrients, hence allowing establishing relationships between consuming organisms and their diets. …”
