【摘要】 １９９４年５—９月，在福建省连江县大官坂垦区试验虾池进行半封闭式对虾养殖技术试验研究，取得相对较明显的经济效益。该半封闭体系具有养殖水质环境较稳定的特点，试验池水体溶解氧含量及其饱和度相对持续较高，整个养殖过程浮游植物种类、数量较稳定，异养细菌总数和弧菌数较低，对预防对虾病毒性疾病有一定效果。更多还原

【Abstract】 he shrimp culture technique of a semi-closed type was tested in a culture pond of the Daguanban Reclamation Area in Lianjiang county,Fujian during May-Sep. 1994 which appeared to have relatively good economical effect. The semi-closed system is characterized by relatively steady aquatic environment, continuous and relatively high contents of dissolved oxygen and saturation, relatively steady contents and species composition of phytoplankton, a low number of bacteria and vibrio, and a relatively strong ability against sudden climatic change. It is effective for the prevention of penaeid shrimp from sudden virus disease.更多还原
