Embodiment Construction

[0043] The present invention will be described in further detail below through specific examples.

[0044] 1. Construction of cultivation pool

[0045] The construction area is 2000m2 in the mid-high tide zone with soft mud or soft mud sandy bottom 2 There are 2 ponds, and the embankment height is 0.6m. The water inlet is set at the high end of the pool length direction, and the water outlet is set at the low end. 100-mesh block, along the length of the pool, dig ditches every 2m, and ditches around the pool. The bottom of the pool is divided into several flat surfaces;

[0046] 2. Pest removal in clear ponds and cultivation of benthic diatoms

[0047] (1) Clearing ponds to eliminate pests

[0048] About 1 month before the start of seedling cultivation (early March to early April), clear the pond with water, for example, in early March, every 1000m 2 Apply 100kg of quicklime to the pool area or put 15kg of bleaching powder into the fish pond to kill diseases and enemies; ...

Abstract

The present invention belongs to the technical field of aquaculture, and relates to a large-scale artificial fingerling cultivation method of boleophthamus pectinirostris. The method comprises the following steps: site selecting, pond establishing, cleaning the pond for eliminating the harm, cultivating benthic diatom, selecting and putting the parent fish, cultivating the parent fish, spawning and hatching, fry rearing, fingerling cultivating, etc. The method of the invention has the advantages of scientific and reasonable property, easy actualization and excellent practicability. The method can realize large-scale artificial fingerling cultivation of large-standard boleophthamus pectinirostris. Furthermore the quality of cultivated fingerling is excellent. The survival rate of cultivated fingerling is high and the economic benefit is excellent.

Description

Technical field: [0001] The invention relates to an artificial seedling raising method for fish, in particular to a large-scale artificial seedling raising method for mudskippers. technical background: [0002] The big mudskipper, commonly known as Huatiao, lives in the intertidal tidal flats of coastal estuaries. It has the characteristics of wide temperature, wide salt, short food chain, low breeding cost, few diseases, natural reproduction in earthen ponds, and long-distance transportation. It has become the southeast of my country. It is one of the famous and high-quality economic fishes developed and cultivated along the coast. In recent years, due to the reclamation of a large area of ​​tidal flats, the natural habitat of the large mudskipper has been reduced. At the same time, due to overfishing and offshore seawater pollution, the natural resources of the large mudskipper have been reduced year by year, and the market price has risen (the current market price of live ...
