通过对象拔蚌( Panopea generosa)不同养殖模式下多种环境因子的分析,筛选出象拔蚌适宜养殖模式,并分析了影响象拔蚌生长的关键环境因子。比较了养殖笼和养殖箱两种养殖模式的养殖效果,前者可立体利用养殖水体,节省空间和养殖设施,降低生产成本,有利于大规模养殖;后者更好地模拟了象拔蚌埋栖特性,饵料充足情况下生长速度要比前者快,并且能更好地躲避敌害。分析了象拔蚌生长过程中的多项环境因子,在满足象拔蚌生长所需的水温条件下,养殖箱与养殖笼中的象拔蚌体重与浮游植物特别是中肋骨条藻的生物量呈正相关(P<0.05),养殖箱中象拔蚌体重以及养殖笼中象拔蚌壳长、体重均与亚硝酸盐氮呈明显的负相关(P<0.05)。研究表明,象拔蚌的生长受养殖模式、环境中的亚硝酸盐水平以及浮游植物丰富程度的影响。
通過對象拔蚌( Panopea generosa)不同養殖模式下多種環境因子的分析,篩選齣象拔蚌適宜養殖模式,併分析瞭影響象拔蚌生長的關鍵環境因子。比較瞭養殖籠和養殖箱兩種養殖模式的養殖效果,前者可立體利用養殖水體,節省空間和養殖設施,降低生產成本,有利于大規模養殖;後者更好地模擬瞭象拔蚌埋棲特性,餌料充足情況下生長速度要比前者快,併且能更好地躲避敵害。分析瞭象拔蚌生長過程中的多項環境因子,在滿足象拔蚌生長所需的水溫條件下,養殖箱與養殖籠中的象拔蚌體重與浮遊植物特彆是中肋骨條藻的生物量呈正相關(P<0.05),養殖箱中象拔蚌體重以及養殖籠中象拔蚌殼長、體重均與亞硝痠鹽氮呈明顯的負相關(P<0.05)。研究錶明,象拔蚌的生長受養殖模式、環境中的亞硝痠鹽水平以及浮遊植物豐富程度的影響。

Through the analysis of various environmental factors under different culture modes, the suitable culture mode and the key environmental factors affecting the growth of Panopea generosa were selected. Firstly, the effects of two culture modes, cage culture and lantern nets culture, on the growth were compared. Cage culture through hanging Panopea generosa could fully utilize the water body, greatly save space and culture facilities, and reduce production costs, which are conducive to intensive farming. While lantern nets culture could better simulate buried habitat characteristics of Panopea generosa, grow more rapidly than cage culture under the conditiond of aboundant food sources, and easily escape from predators. Secondly, the environment factors during growth process were analyzed. When meeting the requirement of water temperature for growth, body weight in lantern nets and cage was obviously positively interrelated to the biomass of phytoplankton, particularly the biomass of Skeletonema costatum (P<0. 05);body weight in lantern nets and both the shell length and body weight in cage was obviously negatively interrelated to the concentration of nitrite-N (P<0. 05). In short, growth of Panopea generosa was affected by the culture modes, nitrite levels in environment environment and the abundance of phytoplankton.
