摘要: Abstract A system of n competing logistical species the Volterra type under proportional harvesting strategy is analyzed. In case selective harvesting, when effort adjusted to each species, optimum may result in total maximum sustainable yield (TMSY 1 ). When it exists, reaching TMSY does not affect stability character, but state, and hence some populations reach too small a value persist nature. If competition strong, with smaller biotic potential be driven extinction. harvested common effort, such as trawler fishery, 2 ) than , all lower or equal will this call for implementation MSY equivalent extermination runs directly against Convention on Biological Diversity ( CBD, 1992 Therefore, legal documents advocating ecosystems starting Johannesburg Plan Implementation JPI, 2002 must urgently retracted replaced adaptive management which respect CBD.
