福建地处亚热带,气候温和,水温适中,盐度适宜,水质肥沃,饵料生物丰富,适合于海水贝类养殖。本省宜于贝类养殖的浅海滩涂有900多万亩,除目前已经利用的之外,潜力还很大。贝类养殖在本省渔业生产中占有特殊的重要地位。提高贝类养殖产量,尤其在目前和今后相当长一段时间,贝类种苗还需主要依靠天然苗种,而天然苗种还不能完全由人工控制的情况下,珍惜有限的苗种,提高贝类产量,有着十分重要意义。 蛏、蛤、蚶、牡蛎是本省传统养殖的“四大贝类”,近年来还引进了一批新的品种,这些养殖贝类的援食习性均属于滤食方式。本文试就贝类滤食性方式与提高养殖产量的相关关系从数理方面进行探讨。
Fujian is located in the subtropical, mild climate, moderate water temperature, salinity suitable, water quality and fertility, abundant biological feed, suitable for seawater shellfish breeding. There are more than 9 million mu of shallow beaches in the province that are suitable for shellfish farming. In addition to the current utilization, there is still great potential. Shellfish farming occupies a special and important position in the province’s fishery production. In particular, at present and for a long time to come, shellfish species need to rely mainly on natural seed species, while natural seed species can not be completely controlled by humans. Therefore, the limited number of seed species and the increase of shellfish species Class production, has a very important significance. The clams, clams, clams and oysters are the “four large shellfish” traditionally cultured in the province. In recent years, a number of new breeds have also been introduced. The aid habits of these cultured clams belong to the filter feeding mode. This paper tries to discuss the relationship between shellfish filter feeding and raising the yield of breeding from mathematical aspects.
