Embodiment 1

[0015] On May 6, 2013, 200 jin of live shellfish of Meretrix meretrix were purchased from the shellfish sales base of Beihai Glass Factory. The following is the real-time situation of the method of the present invention on the batch of shellfish.

[0016] (1) Preparation of nursery ponds: The broodstock breeding pond of Meretrix clam is 4.2m×3.8m, the depth of the pond is 1.2m, and 4 bamboo poles that can exceed the edge of the pond are erected in each pond.

[0017] (2) Placement of broiler breeding baskets: suspend and fix the four corners of 60cm×45cm×15cm rectangular air-permeable and leaky polyethylene plastic baskets on the bamboo poles with strings, the suspension height is adjusted according to the height of the cultivation water body, the general requirement is to cultivate The baby can be submerged 0.2m into the pool, and a basket is suspended every 0.5m.

[0018] (3) Parenting clam into the pool: Before putting clams in the pool, disinfect the whole pool with 20ppmg...

Embodiment 2

[0021] On June 26, 2014, 400 jin of broiler shellfish of Meretrix meretrix was purchased from Waisha Island in the north. The following is the real-time situation of the method of the present invention on the batch of shellfish.

[0022] (1) Preparation of nursery ponds: The broodstock breeding pond of Meretrix clam is 4.2m×3.8m, the depth of the pond is 1.2m, and 4 bamboo poles that can exceed the edge of the pond are erected in each pond.

[0023] (2) Placement of parent shell breeding baskets: Hang and fix the four corners of the 60cm×45 cm×15cm rectangular breathable and leaky polyethylene plastic baskets on the bamboo poles with strings. The suspension height is adjusted according to the height of the cultivation water body. The shellfish can be submerged 0.5m into the pool, and a basket is suspended every 0.5m.

[0024] (3) Parenting clam into the pond: Before putting the clam broccoli into the pond, disinfect the whole pond with 20ppmg potassium permanganate, add fresh ...

Embodiment 3

[0027] On April 26, 2015, 300 catties of clam shellfish were purchased from Dongxing, Guangxi. The following is the real-time situation of the method of the present invention on this batch of shellfish.

[0028] (1) Preparation of nursery ponds: The broodstock breeding pond of Meretrix clam is 4.2m×3.8m, the depth of the pond is 1.2m, and 4 bamboo poles that can exceed the edge of the pond are erected in each pond.

[0029] (2) Placement of broiler breeding baskets: suspend and fix the four corners of 60cm×45cm×15cm rectangular air-permeable and leaky polyethylene plastic baskets on the bamboo poles with strings, the suspension height is adjusted according to the height of the cultivation water body, the general requirement is to cultivate The baby can be submerged 0.3m into the pool, and a basket is suspended every 0.5m.

[0030] (3) Parenting clam into the pool: Before putting clams in the pool, disinfect the whole pool with 20ppmg potassium permanganate, add fresh sand-filt...

Abstract

The invention discloses a temporary culturing fattening and spawning induction method in the meretrix-lyrata artificial breeding process. As meretrix-lyrata parent scallops cannot frequently lay eggs in the temporary culturing stage, or the meretrix-lyrata parent scallops are largely died during temporary culturing, or the high malformation is caused when the spawning quantity is large, the condition is adverse to meretrix-lyrata l breeding production. The method mainly includes the several steps of breeding pond preparing, parent-scallop breeding basket placing, parent-scallop pond entering and culturing managing. According to the measures, the fattening and spawning induction aims during meretrix-lyrata artificial breeding are effectively achieved; the method has the originality and the advance, and has the quite-high use value. The temporary culturing fattening and spawning induction method is high in pertinence, applications are obtained through multiple practices, the using cost is low, operation is easy, and the application effect is good.

Description

technical field [0001] The invention relates to a method for temporarily raising and fattening clams in the process of artificially raising seedlings and inducing spawning, and belongs to the technical field of marine aquatic products. Background technique [0002] Meretrix lyrata, also known as Vietnamese clam and Qin clam, belongs to the family Veneridae and belongs to the genus Meretrix. It is mainly distributed in my country's Taiwan, Guangxi and Guangdong, as well as Vietnam and the Philippines. It is a typical buried type bivalve economic mollusk in the middle and low tide areas of the intertidal zone. Because of its strong adaptability, short breeding cycle, high yield and delicious meat, the shellfish is very popular in domestic and foreign markets. The market demand is increasing, and the price is rising all the way. Relying on imported natural seedlings for breeding can no longer meet market needs. Research results at home and abroad in the past ten years have sho...
