Abstract
The invention discloses a method for ruditapes philippinarums aquiculture in the shallow sea of a subtidal zone. The method comprises the following steps: before ruditapes philippinarums seedling sowing, removing harmful bionts from the shallow sea of the subtidal zone, which has the salinity of 25-32, has a non-polluted substrate and a flat terrain, does not have fresh water injection and serves as a bottom sowing aquiculture area; taking young shellfishes as aquiculture seedlings, wherein the specifications of the young shellfishes are that the lengths are 7-20mm, the density is 600-7000 pieces per 500 grams, the shell color is white, the specifications are uniform, the activity is high and the young shellfishes are not broken; in mid-to-late April, sowing the seedlings into a 10-meter isobath by a wet sowing method, and scattering the seedlings within the range of the aquiculture area in a concentrated manner according to the density of 3,000-5,000 pieces per square meter, wherein the seedling sowing operation is required to be executed at the time of slack water, the specification of the seedlings is equal to or larger than 7mm, and the harmful bionts are regularly removed from the aquiculture area in an aquiculture process; after half a year to two years of aquiculture, the ruditapes philippinarums can be harvested when the ruditapes philippinarums shellfishes grow to be equal to or longer than 4cm and are individually equal to or heavier than 8 grams.
Description
Technical field
The present invention relates to a kind of cultural method of Ruditapes philippinarum, particularly a kind of method of subtidal zone fish-farming in shallow marine water Ruditapes philippinarum.
Background technology
Ruditapes philippinarum is the main marine shellfish of China, and Zhuanghe, Liaoning Province, Yi Dai coastal area, Pulandian are the main producing region of China's Ruditapes philippinarum and important export base, and its production form is mudflat aquaculture.But in recent years because of reasons such as coastal engineering, environmental pollutions, the atrophy of Ruditapes philippinarum mudflat aquaculture large area, industry development is faced adverse conditions.Therefore if can carry out the cultivation of Ruditapes philippinarum in the marine site beyond beach, can avoid the problem of dwindling because of above-mentioned cultured area former thereby that cause, be conducive to carrying on and expanding of Ruditapes philippinarum cultivation.
Summary of the invention
The present invention is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of method of non-beach area cultivation Ruditapes philippinarum, and it can significantly expand the space of Ruditapes philippinarum cultivation.
Technical solution of the present invention is: a kind of method of subtidal zone fish-farming in shallow marine water Ruditapes philippinarum, is characterized in that: described method is carried out according to following steps:
A, select salinity 25-32, substrate is pollution-free, physical features is smooth and the subtidal zone neritic area injected without fresh water as bottom sowing culture district, the removing of harmful organisms is carried out in culture zone before broadcasting seedling,
B, to select specification be the long 7-20mm of shell, 600-7000 grain/500g, shell look fair, specification is even, energetic, unabroken young shellfish is as cultivating seed,
C, in mid or late April, adopt and wetly to broadcast method broadcast seedling in 10 meters of isobaths, within the scope of culture zone according to 3000-5000 grain/m
2density concentrate and to sow, and broadcast when seedling operation should be chosen in slack tide and carry out, seed size is more than 7mm, and regularly the removing of harmful organisms is carried out in culture zone in breeding process,
D, through the cultivation of a year and a half to two year, more than japanese littleneck shell grows to 4cm, more than whose body weight reaches 8g, adopt collecting and obtain.
Compared with the existing technology, tool has the following advantages in the present invention:
Ruditapes philippinarum disclosed in this invention shallow sea aquaculture technology, is the great innovation to Ruditapes philippinarum cultural technique, and it expands to 10 meters of isobath shallow waters along the coast of subtidal zone by the depth of water of Ruditapes philippinarum cultivation, and breeding spaces has been increased to decades of times.Compare with mudflat aquaculture, it is strong that fish-farming in shallow marine water has opposing adverse circumstances ability, is subject to the advantages such as high temperature, impact freezing and rainfall are little; And because subtidal zone is without revealing the empty time, extended effective ingest time, and growth rate and coefficient of condition increase substantially, and the culture-cycle also significantly shortens accordingly.This technology is the important development to tradition cultivation theory and technology, is a major transformation on intertidal shellfish breeding way, therefore can say that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market prospects are very wide.
Embodiment
The specific embodiment of the present invention will be described below.
The selection in bottom sowing culture district.Select subtidal zone neritic area as bottom sowing culture district, its seawater quality need meet breeding water standard, salinity 25 ~ 32, and substrate is pollution-free, and physical features is smooth, without fresh water, injects.And before broadcasting seedling, the mode such as adopt trapping, diver's diving to adopt to catch remove harmful organisms.
Seed is selected and transportation.Select that specification is shell long 7 ~ 20mm, 600-7000 grain/500g, shell look fair, specification is even, energetic, unabroken young shellfish is as cultivation seed.Container Refrigerated Transport on the rocks for seed, and prevent in transit Exposure to Sunlight, air-dry and drench with rain etc., keeps moist environment, and gathered the same day, transportation on the same day, to guarantee the survival rate of seed.
Between the sowing time end, mode and the end broadcast specification, density.In the middle ten days and the last ten days in April, adopt and wetly to broadcast method broadcast seedling in 10 meters of isobaths, with ship, clam seedling is transported to the cultivation neritic province domain that is plugged sign, within the scope of sign according to 3000 ~ 5000/m
2density concentrate and to sow, and broadcast seedling and need when slack tide, carry out because clam son needs certain Diving Time after sowing, selected seed size need be more than 7mm, otherwise affects survival rate.The general seedling 7-10mm(5000-7000 grain/500g that adopts), middle seedling 15mm(1200-1500 grain/500g), seedlings 20mm(600-700 grain/500g) broadcast specification at the bottom of three kinds, and owing to sowing density and seed size is inversely proportional to, thus the end broadcast density should be at 3000/m
2sow above, and in conjunction with concentrating.
Remove harmful animal.Prior to seeding with breeding process in, all need cultivation marine site to carry out the removing work of harmful organisms, as conch, starfish etc., for means such as these harmful organisms adopt trapping, diver's diving to adopt to catch, regularly remove harmful animal.
Adopt and catch.Through the cultivation of a year and a half to two year, more than japanese littleneck shell reaches 4cm, individual weight reaches 8g when above, can adopt collecting and obtain.
Utilize this method to carry out the cultivation of Ruditapes philippinarum, its cultivation depth of water can reach in 10 meters of isobaths, through examination application, more than its average yield per mu 1000kg, is up to 3500kg.Compare with periphery mudflat aquaculture, the growth rate of Ruditapes philippinarum improves 67.9%, and survival rate improves 50%, and coefficient of condition improves 26.9%, and the culture-cycle has shortened more than 6 months, and per mu yield improves more than 90%.
