利用1999～2001年课题组在台湾海峡及邻近海域采集的海洋渔业资源生物资料和在岸上采集的生产技术资料,通过分析渔业资源种类组成和结构、测算初级生产力,检测浮游植物含碳率,鱼类、虾蟹类、头足类等主要种的营养级及其含碳量率、测算生态效率;利用Cushing模型和营养动态模型估算该海区的潜在渔业资源量,利用Cadima经验公式和Gulland经验公式估算渔业资源最大持续开发量。结果表明,该海区的潜在渔业资源量为250.34×104t,最大可持续开发量为136.98×104t。2000年该海区的实际年捕捞量为217.2×104t,超过了渔业资源的剩余产量80.22×104t。因此,为了持续利用该海区的渔业资源,应减少投入捕捞力量和实行捕捞限额制度。
Based on the biological data of marine fishery resources collected in the Taiwan Strait and its adjacent waters from 1999 to 2001 and the production technical data collected onshore, the primary productivity was estimated by analyzing the species composition and structure of fishery resources. The carbon sequestration rates of phytoplankton, Cushing model and nutrition dynamic model were used to estimate the potential fishery resources in the sea area. Based on the Cadima empirical formula and the Gulland empirical formula Estimate the maximum sustainable development of fishery resources. The results showed that the potential fishery resources in the sea area were 250.34 × 104t and the maximum sustainable development was 136.98 × 104t. The actual annual catch in the sea area in 2000 was 217.2 × 104t, surpassing the remaining production of fishery resources of 80.22 × 104t. Therefore, in order to continue to utilize the fishery resources in the sea area, the fishing effort should be reduced and the fishing quota system should be implemented.
