卵的大小影响幼虫的大小、生长速度、存活率和繁殖力,通过在卵的大小和繁殖力之间进行权衡来最大化母体适应性。在食物条件差的情况下,产生少量的大卵可以最大限度地提高雌性的适应性,在食物条件丰富的情况下,产生大量的小卵也是如此。Gnathopogon caerulescens(Honmoroko)从春季到夏季在很宽的水温范围内产卵。因此,我们确定是否卵大小随水温变化,以及卵大小如何影响孵化大小在不同的水温。卵大小的变化与湖泊周围水温的季节性变化密切相关,无论时间和区域如何。一项使用湖中蛋的实验表明,在24 °C的水温下,孵化的大小与蛋的大小有显着的正相关关系。另一方面,较低的孵化温度,类似于产卵季节开始时可能遇到的温度,导致孵化出的幼体较小,卵需要较长的孵化时间。因此,在产卵季节开始时,由于温度相对较低,在本莫罗科的自然环境中,卵的大小对孵化大小的影响可能较小。虽然低于一定阈值的有效身体大小的鱼苗通常不会有一个高的早期存活率,由于,例如,较低的竞争能力或高的敏感性捕食,季节性卵大小的变化在Honmoroko可能是自适应的,以提高早期生存的可能性,通过建立一个有效的身体大小在不断变化的水温条件下。
Egg size affects larval size, growth rate, survival and fecundity with maternal fitness being maximized by a trade-off between egg size and fecundity. Production of a small number of large eggs maximizes female fitness under poor food conditions, as does a large number of small eggs under rich food conditions.Gnathopogon caerulescens(Honmoroko) spawns over a wide range of water temperature from spring to summer. Thus, we determined whether or not egg size varied with water temperature and how egg size influenced hatchling size at different water temperature. Changes in egg size strongly correlated with seasonal changes in water temperature around the lake, regardless of time and area. An experiment using eggs from the lake indicated that hatchling size has a significant positive relationship with egg size in water temperatures of 24 °C. On the other hand, a lower incubation temperature, similar to that likely to be encountered at the beginning of the spawning season, resulted in a smaller hatchling size, eggs requiring a longer time to hatch. At the beginning of the spawning season, therefore, egg size may have a lesser impact on hatching size in the natural environment of Honmoroko because of the relatively lower temperatures. Although fish larvae below a certain threshold of effective body size are generally not expected to have a high early survival rate due to, for example, a lower competitive ability or a high susceptibility to predation, seasonal egg size variation in Honmoroko may be adaptive so as to enhance the likehood of early survival by establishing an effective body size under changing water temperature conditions.
