福建省南安市石井东港养殖场,利用两口沙泥底质虾池(80亩)进行花蛤育苗试验,取得显著的经济效益。去年10月份投放亲蛤7500公斤,经7个月精心管理,培育出个体大、健壮、规格为每公斤3000粒左右的花蛤苗种17.5万公斤,总产值75万元,亩均纯收入8000多元。现将主要做法简介如下: 一、育苗前的准备 1.清池、翻晒:该虾池在上半年养殖斑节对虾失败后,马上进行清淤清污和晒池,7月上旬用牛彻底翻犁一遍,翻犁后再晒池。翻犁的目的在于起消毒、氧化、改良底质作用,且利于贝苗钻土栖息。 2.消毒:虾池在育苗前进水浸泡、交换数次,使PH值稳定在7.8～8.4之间。同时用生石灰进行消
Fujian Province, Nan’an Ishii Donggang farms, the use of two mud bottom shrimp ponds (80 acres) for clam nursery trials, and achieved significant economic benefits. In the past year, it put in operation 7500 kilograms of clams. After seven months of careful management, it nurtured a large and robust individual with a capacity of 175,000 kilograms of clams and seeds of about 3,000 grains per kilogram, with a total output value of 750,000 yuan and a net income of 8,000 yuan per mu Multiple. Now the main approach is as follows: First, the preparation before nursery 1. Clear pool, turn the sun: the shrimp ponds in the first half after the failure of P. monodon breed, immediately dredged clear and sun pool, in early July with cattle thoroughly turn Plow again, turn plow and then sun pool. The purpose of turning plow disinfection, oxidation, improve the role of sediment, and help Baimiao soil habitat. 2. Disinfection: shrimp ponds soaked in water before raising seedlings, exchanged several times, the PH value stabilized at 7.8 to 8.4. At the same time with quick lime to eliminate
