Spawning periods represent critical times for production and vulnerable times for harvesting of fish stocks and it is important to understand their causal basis. This research project explores a new hypothesis in order to explain the patterns of mating in pelagically-spawning marine fishes: the hypothesis is that, spawning sites and times are selected in order to improve fertilization success rates. Previous studies have shown that for the bluehead wrasse, Thalassoma bifasciatum, the timing of mating varies dramatically between local populations, that mean fertilization rates are surprisingly low and appeared to be influenced by turbulence and location on the reef, and that the number of sperm released by males correlates significantly with the size and fecundity of the female with whom they are mating. This project will undertake three interrelated investigations on: 1. the timing of mating, 2. the location of mating, and 3. fertilization success.

产卵期代表生产的关键时期， 捕捞鱼类种群的脆弱时期， 来理解它们的因果关系 该研究项目探索 一个新的假说来解释 远洋产卵的海洋鱼类：假设是， 选择产卵地点和时间， 受精成功率。 先前的研究表明，对于 蓝头濑鱼，双带海锦鱼，交配的时间 在当地人群中差异很大，这意味着 受精率低得惊人， 受到湍流和珊瑚礁位置的影响， 男性释放的精子数量与 与之交配的雌性的大小和繁殖力。这 该项目将进行三项相互关联的调查：1。的 交配时机，2.交配的位置，以及3.施肥 成功
