Artificial shrimp feed
Abstract
Abstract COVERS AN ARTIFICIAL TEXTURIZED FEED USEFUL IN GROWING SHRIMP WHICH COMPRISES A DOUGH-LIKE COMPOSITION KNEADED OR EXTRUDED INTO A FORM RESEMBLING VERMICELLI AND INCLUDING A PROTEIN SOURCE AND A GUM BINDER. A PREFERRED PROTEIN SOURCE IS CORN GLUTER, AND A PREFERRED GUM BINDER IS A STARCH HUM. A PARTICULARLY USEFUL FEED CONTAINS CORN GLUTEN, STARCH GUM AND YEAST, AND MAY CONTAIN OTHER INGREDIENTS, PARTICULARLY OTHER PROTEIN SOURCES. THE FEED IS OF A FORM RESEMBLING VERMICELLI OR SPAGHETTI AND IS OF A SIZE LARGE ENOUGH TO BE NOTICED BY THE SHRIMP WHEN FEEDING, AND YET OF A SIZE SUFFICIENTLY SMALL SO THAT THE SHRIMP CAN STILL CLUTCH IT. IT IS GREATLY PREFERRED THAT THE SHRIMP FEED BE IN THE FORM OF ROUNDED PIECES WHICH HAVE BEEN EXTRUDED OR KNEADED TO A LENGTH OF ABOUT 4.0-6.3 MM, AND A DIAMETER OF 1.0-3.0 MM. THE SHRIMP FEED PROVIDES A FOOD OF AN EXCELLENT LOW CONVERSION RATIO, AND DOES NOT CAUSE CONTAMINATION OR POLLUTION OF THE CULTURE WATER OR SAND BED DUE TO ITS PARTICULAR CONFIGURATION AND RELATIVE WATER-INSOLUBILITY.
