Problems solved by technology

However, due to the continuous expansion of aquaculture scale, the single method of aquaculture, and the imbalance of shallow sea ecological environment and other factors, there are frequent phenomena such as slow growth, small individuals, and large individual differences in the aquaculture of marine shellfish.

Embodiment 1

[0015] In March 2018, in Xuwen, Zhanjiang, the Huagui scallops were divided into three groups with a water depth of 1 meter, a water depth of 2 meters, and a water depth of 3 meters. In each water depth group, 20 scallops, 40 scallops, and 60 scallops were set in each net Three different breeding density groups of cages (net cage cylindrical, diameter 40cm * height 60cm, the distance between adjacent mesh cages is 3m), each water depth group and density group repeat three groups of experiments, and the sea culture is 3 months, June ends. In the breeding experiment, the 3-month-old Chinese clam scallop was selected, with a shell height of 32.17±2.1mm, a shell length of 28.17±1.86mm, a shell width of 9.24±0.87mm, and a weight of 4.34±0.93g. After breeding for 3 months, its size traits are specifically shown in Table 1, and the specific growth results are as follows figure 1 As shown in Table 2, it shows that the relative growth rate of shell height, shell length and shell width...

Abstract

The invention discloses a culturing method capable of promoting growth of chalmys nobilis. The culturing method disclosed by the invention is characterized in that in a culturing process, chalmys nobilis at age of 3 months can be put in specific water depth and specific culturing density; the water depth of 1 meter can obtain sufficient temperature and illumination, so that rich biological fish bait can be obtained; due to the culturing density of 20numbers / net cage, water flows smoothly, and the problem of fighting for the fish bait is reduced, and therefore, the growth speed of the chalmys nobilis is obviously improved, the culturing time is greatly shortened, and the culturing cost is reduced. Compared with a culturing way of no differentiation of water layers and culturing density, theculturing method has the advantages that the individual sizes and the growth ratios are wholly improved.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a culture method for promoting the growth of scallops. Background technique [0002] Chlamys nobilis is a warm-water shellfish that is naturally distributed in Honshu, Shikoku, and Kyushu in Japan, the South China Sea in China, and Indonesia. It is distributed in Haimen, Zhelang, Daya Bay, Dapeng Bay, Zhapo and other places along the coast of Guangdong Province. Luxurious Chlamys farreri is a sea treasure produced in the subtropical zone and can be eaten fresh. Its adductor muscle dried product is commonly known as "dried scallop". It is a rare sea treasure with high nutritional and economic value, and has obvious agricultural "three highs" characteristic. In the coastal area of ​​Guangdong, Chlamys farreri can grow every year. Its breeding cycle is relatively short (about 1 year), its yield is relatively high, and its economic benefits are significant. It is a shellfish ...
