Problems solved by technology

However, although countries such as Spain, New Zealand, Australia, and Brazil have generally enhanced seahorse bait to varying degrees during seahorse breeding, the growth and survival rates of juvenile seahorses vary greatly due to different enhancement methods

[0017] The present invention is further explained below in conjunction with the examples, but the examples do not limit the present invention in any form.

[0018] test group

[0019] Between April 20 and July 20, 2010, there were 200 lined seahorse seedlings each of E1, E2 and E3, and the breeding process was carried out according to the aforementioned steps in this manual:

[0020] Artemia hatches and grows, and rotifers are cultivated using rice bran and chlorella. Fortification with feed enhancer (Super Selco, INVE (Thailand) Ltd.) and microalgae (Chlorella, Chlorella vulgaris Beij ) to carry out secondary strengthening. The specific parameters are: temperature: 22-28°C; pH: 7.9-8.5; Super Selco 0.6g / L, Chlorella concentration 1×10 7 each / mL, inflate evenly to ensure that the dissolved oxygen is not less than 5mg / L, the density of Artemia worms is 50,000-100,000 / L, the salinity is 150‰, the strengthening time is 24 hours, the density of rotifers is 500,000-1000,000 / L, s...

Abstract

The invention discloses a method for improving a hippocampus kelloggi fry cultivating rate. The method for improving the hippocampus kelloggi fry cultivating rate is characterized in that nutrition is fortified on main animal bait for hippocampus- Artemia by using an unsaturated fatty acid emulsifier and microalgae so as to compensate unbalance of the trophic structure of the bait, in particular to increased and balance the content of the unsaturated fatty acid. After the bait is fortified based on the method, the bait is continuously fed to a young hippocampus, thereby significantly improving the bait feeding rate of the hippocampus; and by soaking and cleaning the fortified bait, and the survival rate and the growth rate of the corresponding hippocampus are significantly increased.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a method for increasing the growth rate of lined hippocampus seedlings. Background technique [0002] Higher unsaturated fatty acids are essential nutrients for the growth and development of seawater juvenile fish, which can effectively improve the immunity of fish and ensure normal growth and development. Conventional larvae and juvenile fish bait organisms include n-3 unsaturated fatty acids such as DHA of rotifers and Artemia themselves, which cannot meet the needs of fish growth, and bait organisms must be nutrient-enhanced to meet the nutritional needs of fish bodies. Copepods (small and medium-sized, such as Daphnia sinensis) are a kind of biological bait with relatively high content of unsaturated fatty acids, but their particle size is basically in the range of 1-3mm, which cannot meet the needs of newborn hippocampus (bait < 1mm). ) and bait requirements for ...
