  1.龙虾幼苗的孵化：龙虾幼苗的孵化一般在5、6月开始，卵粒受精后由棕黑色变棕色，至孵化前卵粒又变成透明红色，不透明者为死卵。一个个体的孵化需10—20天，但是孵化高峰期只有数日，孵化的时间是从太阳刚落山开始到半夜为止。刚孵化的幼体浮游于表层，随着水流集中于排水口的网槽中，第2天早晨用网捕获浮游表层的幼体。

  3.浮游期幼体和水流：一般情况下，暴气是饲养甲壳类幼体的一项极为有效的措施，但暴气不能太强，如果采用强暴气措施，幼体头胸甲与鳃之间出现气泡，导致幼体浮头死亡。随着小龙虾苗种山西11选5走势图发育的进展，幼体下沉水池后，只要不产生从底部向上强烈的水流，龙虾一般难于再浮游到海水表面。暴气如果太强，幼体体表和鳃容易被水池底部的有机物覆盖，影响幼体活动和呼吸，引起体质衰弱。

  在自然界生长的幼体，只捕食端足类，多毛类等小动物，由于龙虾种苗具有潜伏习性，能逃脱天敌的捕食。但是，这种习性并不是生理上的必需条件，在龙虾不能挖掘巢穴的底质，用笼子也能饲养。在底部铺设牡蛎壳的混凝土水池放养第Ⅳ期幼体，成活率大约为80%。龙虾苗种通常是以变态后第Ⅳ期幼体作为苗种放养，但第Ⅳ期幼体不能完全进入底栖生活，这是导致放养后死亡的原因。

  大自然中的龙虾主要是栖息在沙泥质的海底，每穴潜伏一尾，但在交尾期，雌雄配对潜伏，有时也潜伏于岩石的空隙中，而日本龙虾是属群栖生活。淡水龙虾山西11选5走势图在饲养期间必须进行投饵，要考虑各种附着生物是否可作为饵料加以利用，为此日本曾进行海中垂下养殖试验。
