Recipes of mixed fodders for cultivation of different species and ages of fish industrial fish farming and their quality
Combined fodder or animal feed is a complex homogeneous mixture of treated and milled to the desired particle size of the various additives and microadditives, produced by science-based recipes and ensure proper feeding of animals, including fish.
Feed produce public and private animal feed enterprises in the form of loose, granulated (granules of various sizes — grains, dust), as well as piketirovanijah of science-based recipes developed by research organizations.
Feed are divided into starting and production. Production recipes to feed include feed for the cultivation of commodity fish and can be attributed to feed manufacturers, and to start for growing juveniles, from the rearing of fish larvae to rearing of fingerling. Everything worked out of feed should be complete, that is, the feed needs to satisfy the needs of fishes in nutrient, mineral and biologically active substances.
Scientific theoretical basis of cost-effective feed is the optimal selection of feeds with a specific ratio of protein, amino acids, fat,carbohydrates, energy, vitamins and minerals.
Recipes of mixed fodders, as a rule, develop fishery research organizations on the basis of the modern level of knowledge about nutrition and getting the productivity of different fish species in the cultivation of peaceful and predatory fish species in fish farms.
Each recipe is designed to feed intended for growing different species and age, is assigned a number. According to the State standard for pond fish assign 110-119, 110 for starting, 111, 112, 113, etc. for production. Developed in the research organizations assign their own numbers, for example, RC-S, RGM, and others.
The number and composition of feed is presented below in sections 2.1. and 2.2.
2.1. State standard recipes of mixed fodders for cultivation of uneven-aged carps in ponds
Feed mills, developed and approved recipes are made mainly of feed for different ages of growing carp in ponds on the recipes, which are presented in table. 7. Currently, however, these recipes can make and privatized plants.
The compositions of recipes of mixed fodders for cultivation of different ages carp fish supplied by the State owned feed mills, %
The cultivation of fry and marketable carp on these recipes feed is conducted by technologies developed by scientific institutions. Made for growing carp feed feed enterprises in the form of granules or crumbs put in a fish farm in loose or packaged form and they are accompanied by a special form and content of quality certificates.
2.2. Industry recipes of compound feeds approved by the Ministry of fisheries of the USSR
for the cultivation of different species and ages of fish
Domestic and world practice pokachivaet that feeding fish full of feed, allows to achieve maximum productivity with simultaneous cost reduction of feed per weight gain, and secure and maintain the health of cultured fish.
For the cultivation of different species and ages of fish research organization has developed a number of recipes of compound feeds. the compositions of which are provided below, approved by the Ministry of fisheries of the USSR.
These recipes are full of feeds that are recommended to use in intensive and semi-intensive rearing of different species and ages of fish held in conditions of ponds, net cages, cement pools, and other containers.
In developing their participated IFF (major), Ukrniira, Lanier, Kressner, Kaspnirh and others.
The production of fish feed formulations has been established in the Dnipropetrovsk special granulated feed factory fish equipment was purchased in Japan.
RECIPE RC-With the starter feed for the rearing of larvae and fry of carp and herbivorous fish weighing up to 1 g
Made of pulverized starter feed is suitable for rearing of carp larvae in the trays for normal and warm waters on the standards developed by scientific organizations. With the use of it in the period of rearing for a short period of time (14-30 days) you can reach average weight before I g
In order to effectively feeding the starting feed schedule should be growth and regularly carry out control capture, and the results compared with the schedule growth. When stunting, you must find the cause and continue the growth of the larvae.
