Problems solved by technology

In contrast, three-spotted seahorses, large seahorses, and Japanese seahorses are local species in the coastal areas of my country, and there have been many years of breeding reports. However, according to previous reports, the cultivation efficiency of the above three types of seahorses is relatively low. The main reason is that in The survival rate and growth rate in the grow-out period (2-6 months old) are relatively low, and there is also a lack of necessary seahorse grow-up techniques, such as bait feeding methods, reasonable screening of breeding facilities, etc.

Embodiment Construction

[0023] The present invention is further explained below in conjunction with the examples, but the examples do not limit the present invention in any form.

[0024] From May 2010 to September 2010, the experiment lasted for 5 months. The experimental site is the seahorse breeding base in Zhanjiang City, Guangdong Province. 3,600 American lined hippocampus were used in the experiment, 2 months old, with a body length of 55.2±9.4mm and a weight of 0.88±0.24g. All provided by the South China Sea Institute of Oceanology, Chinese Academy of Sciences. The experimental seahorses have been pre-acclimated. The pre-acclimation uses multiple feedings in the same place and attracts the seahorses to eat by disturbing the water body, so that they can better eat frozen bait.

[0025] 1. Breeding environment: aquaculture in glass tanks (0.8m*0.8m*0.8m), with sand-filtered seawater as the water for cultivation, aquaculture density of 20-100 tails / m3, semi-flowing water aquaculture, and enviro...

Abstract

The invention discloses an optimized feeding method for hippocampus cultivation period (2-6 months old), specifically including the seahorse breeding environment, bait type, bait feeding time, bait feeding amount, bait feeding method and bait treatment Reasonable arrangement and optimization of methods. By adopting the bait feeding method of the present invention, the survival rate and growth rate of the hippocampus in the growth period are significantly improved, and the bait coefficient is reduced at the same time, which can finally realize the improvement of the overall breeding efficiency of the hippocampus and reduce the degree of ecological pollution.

Description

technical field [0001] The invention belongs to the field of seahorse breeding methods and technologies, in particular to a method for optimizing the feeding of seahorses in the growing period. Background technique [0002] Seahorse farming can be divided into three stages: juvenile fish nursery, juvenile fish rearing, and broodstock breeding. Cultivation of juvenile fish is the longest stage of seahorse culture, which directly determines the final output and cost of seahorse culture. Feed feeding not only directly determines the nutrient intake level of seahorses, but also a key process to control the cost of breeding and maximize the profit. At present, there have been relatively systematic reports on the bait feeding techniques and methods in the juvenile period of seahorses, but there is no introduction on the bait feeding techniques or methods in the growth period (juvenile seahorses born 2 months to 6 months of sexual maturity). Generally speaking, the scientific man...
