摘 要:针对大弹涂鱼传统养殖范式缺陷进行多茬养殖和新技术研究.结果表明:采用投放高密度鱼苗、年养多茬、分阶段分养模式配合新技术,单位面积总产量和产值均是传统范式的一倍;不晒坪管理的大弹涂鱼体重生长快,当年即可收获,而晒坪管理的生长缓慢,翌年6月才能收获;施放底栖硅藻培养基的大弹涂鱼比施放鸽粪的体重生长更快,可提高23.45%;4~11月采用封闭洞口结合网笼法收获,一次即能收获池中商品鱼80%以上,与网笼法收获4次的效果相当.The paper reveals the new technique on the annual multiple-breedings of Boleophthalmus pectinirostris against conventional breeding. The results are as follows: The total production per unit area has been doubled with the new breedings. Boleophthalmus pectinirostris in no-sunning fiat gets more weight quickly than that in the sunning fiat which has to be harvested the next year. The fish with the feeding of marine benthic diatom grows more quickly than that on the pigeon-droppings-based feeding, with an increase of 23.45%. More than 80% of the marketable fish can be obtained one time from April to November, with hole-closed and net-cage, which provides the same production as in net- cage four times.
