Abstract |
1. The relationship between starfish numbers and fishing effort is a quadratic, meaning that, as fishing effort increases, starfish numbers also increase until they reach a turning point, after which starfish numbers decline as fishing effort further increases.2. This relationship, although significant, is fairly weak, suggesting that other factors must strongly influence starfish numbers.3. Until we know more about the ecology and population dynamics of starfish populations, it will be difficult to determine the exact extent of the impact of beam trawling on starfish populations. |
