Method for ruditapes philippinarums aquiculture in shallow sea of subtidal zone

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 [0001] The invention relates to a method for cultivating Philippine clams, in particular to a method for cultivating Philippine clams in subtidal shallow seas. Background technique [0002] Philippine clams are the main marine shellfish in China. The coastal areas of Zhuanghe and Pulandian in Liaoning are the main production areas and important export bases of Philippine clams in my country. The production form is tidal flat farming. However, in recent years, due to coastal engineering, environmental pollution and other reasons, the clam farming in the Philippines has shrunk in a large area, and the industrial development is facing difficulties. Therefore, if the culture of Philippine clams can be carried out in sea areas other than tidal flats, the problem of the reduction of the culture area caused by the above-mentioned reasons can be avoided, which is conducive to the continuation and expansion of the culture of Philippine clams.
