Multispecies AnalysisThe tradition in most fisheries science has been to treat each species and stock as a separate entity to be analyzed and managed. We all know that species in ecosystems interact with one another through processes like pre-dation and competition, yet we normally ignore these interactions作者: 孤僻 時(shí)間: 2025-3-22 01:02 作者: 多節(jié) 時(shí)間: 2025-3-22 08:32

Harvest Strategies and Tactics fish reach the spawning grounds. This type of harvest strategy is also known as a constant-stock-size strategy. Another type of harvest strategy involves taking a constant catch, or fixed quota, from the stock every year.
