The Regulative Methods of Ecological FactorsCultivating Environment of Soft-shelled Turtle (Trionyx sinesis)
摘要/Abstract
温度、光照、水质等生态因子是中华鳖养殖中的关键因素.笔者根据相关研究对中华鳖养殖中生态因子的调控措施进行了有益的探索,其主要内容包括:保持恒定水温;较低的水体透明度;充足容氧;不额外补加光照;无沙、无网养殖池;设晒背台、改善小生境等.
Water temperature,water quality and light are very important ecological factors in soft-shelled turtle aquaculture.This article consulted the former relative researches, picked up the proper way to regulate the factors.The main contents were as follows:putting calefaction tubes on the bottom of rearing pools and heat the water directly.Using temperature regulation instruments to keep the wa-ter temperature in the proper range; adding enough dissolved oxygen, undertaking antisepsis every 15 days.Keeping the water diaphaneity in the range of 25～30cm.We suggest that the method of pro-longing illumination at night should not be taken.Turning the four square corners of rearing pool intoarcs contributes to the animal's distribution uniformly to avoid biting each other.It is not necessary to put sand in ponds,while setting basking desks on surface of water is more useful for turtles to save en-ergy.
