Description
Technical field
The present invention relates to fish feed, more specifically relate to small-sized cyprinid fish Gobiocypris rarus (Gobiocypris rarus) scrod feed, also relate to a kind of preparation method of Gobiocypris rarus scrod feed simultaneously.
Background technology
Gobiocypris rarus (
gobiocypris rarusye et Fu) belong to Cyprinidae, Minnow subfamily, Minnow crucian carp belongs to, popular name Jin Bainiang, English name Rare Minnow, be China distinctive be a kind of small-sized predacious fish." Cao Wenxuan; Wang Jianwei; 2003. Gobiocypris rarus----a kind of new Fish as Laboratory Animal. Laboratory Animal Science and management; S1:96-99 " in comprehensive description from last century the nineties from the beginning of, Gobiocypris rarus has been launched to large quantity research, comprised distributed areas, life habit, morphological feature, caryogram, isodynamic enzyme, the many aspects such as breeding of growing.Gobiocypris rarus small (adult fish 3-8cm), maturity period short (4 monthly ages can reach sexal maturity), egg laying amount is large, belong to Continuous batch spawner, under preference temperature, can realize year-round spawning, embryo is larger and transparent, oxygen and the higher biological properties such as adaptive capacity of carbon dioxide are become to a kind of desirable animal used as test, at present at genetics of fishes, fish genetics, the science of fish disease, the fields such as environmental science obtain applying more widely, the chemicals of Ta Shi Chinese Ministry of Environmental Protection regulation is imported and exported domestic biological subject (the < < chemicals method of testing > > detecting, Chinese Ministry of Environmental Protection, China Environmental Science Press), and formulated Gobiocypris rarus acute toxic test concerned countries standard (
gB/T 29763-2013).
All the time, Gobiocypris rarus is cultivated as Model fish.In " quality of heredity of < < animal used as test is controlled > >; quadrate lope happiness etc.; China Standard Press ", point out as animal used as test, comprehensive quality-monitoring be must carry out, Laboratory Animal Standardization and standardization made.Its nutritional need research is different from general cultivation kind, compares growth rate, feed conversion rate and economic benefit etc., and the standardization that should more focus on raising is will guarantee its high-quality.At present for general cultured fishes, had a large amount of perfect compound feeds, but less with the basic nutritional need research of fish for small test, mixed feed is still in deficiency state.Under natural conditions, the small waters such as Gobiocypris rarus happiness rice field, irrigation canals and ditches, the zooplankter that mainly ingests, water earthworm, insect larvae etc.; The daily cultivation in laboratory adopts natural live bait to throw something and feed, as water earthworm, chironomus larvas etc.No matter some commercially available mixed feeds are in physical property or trophic component, are all difficult to guarantee the Growth and reproduction of Gobiocypris rarus.Although natural bait can meet the nutritional need of Gobiocypris rarus growth, 4 monthly age accessibilities are ripe, and body is about 3cm, body weight 0.4-0.5g, and natural live bait can carry a large amount of pathogens conventionally, may cause adverse influence to fish.The live bait that adopts difficult quality to control is thrown something and fed and is tested fish, is difficult to guarantee experiment fish health and homogenieity.The artificial problem that coordinates complete feed can solve bait microorganism, parasite interference, thus make Gobiocypris rarus in trophic level, reach the demand of Laboratory Animal Standardization, can to feed, carry out quality control according to other requirement of animal used as test level.Gobiocypris rarus feeding quality, except the demand to nutritional labeling, also comprises feed palatability etc., because individuality is less, can feed granules size be directly concerned and is successfully ingested.
Research about aspects such as Gobiocypris rarus bait is less, " research of Gobiocypris rarus to Feeding Ability of Culex Pipiens Larvae amount ", < < aquatile journal > >, Wang Jianwei, 1993, in 17:290-292, proposed Gobiocypris rarus the active of Ability of Culex Pipiens Larvae is ingested, and food ration is larger, " the biochemical composition research of Gobiocypris rarus and feed thereof ", < < aquatile journal > >, Wu Zhi is strong etc., 1999, in 23:697-699, measured the biochemical composition of Gobiocypris rarus live bait water earthworm and some man-made feeds, and studied the muscle of Gobiocypris rarus under different feeding conditions, the biochemical component of sexual gland, comprise moisture, protein, fat, ash content, can be worth etc., result shows that water earthworm can guarantee the normal growth and breeding demand of Gobiocypris rarus, but the man-made feeds that herein adopt are commercial feeds of young soft-shelled turtle, its trophic components etc. are for Gobiocypris rarus, also need to adjust to some extent and perfect, " research of man-made feeds on Gobiocypris rarus breeding impact ", < < Sichuan animal > >, Wu Zhi is strong etc., 2001, in 20:174-176, adopted water earthworm and 4 kinds of horizontal artifical compound feeds of high protein to study Gobiocypris rarus breeding nutritional need, although artifical compound feed is thrown something and fed, lower Gobiocypris rarus can carry out breeding activity, but be difficult to reach the effect that water earthworm is thrown something and fed, the long or egg laying amount of Egg-laying interval is lower etc.In sum, up to the present, the research of still not filling a prescription about the full price man-made feeds of Gobiocypris rarus juvenile growth.
Summary of the invention
The object of the invention is to be to provide a kind of Gobiocypris rarus scrod feed, formula rationally, easy to use, met the nutritional need of the daily growth of Gobiocypris rarus juvenile fish, replaced or partly replaced live bait and thrown something and fed, reduced that live bait carries the impact on Gobiocypris rarus quality such as pathogenic microorganism, poisonous and harmful substances, improved the homogenization of Gobiocypris rarus as Quality of Experimental Animals.
Another object of the present invention is the preparation method who has been to provide a kind of Gobiocypris rarus scrod feed, easy to implement the method, easy and simple to handle, met the demand of Gobiocypris rarus small fishes to mixed feed physical aspect, reached Gobiocypris rarus to the demand of feed palatability and guaranteed the stability of granule feed in water.
