Abstract
The invention relates to a fry temporary rearing system made from PVC pipes and a breeding method thereof, belonging to the technical field of aquaculture. The fry temporary rearing system comprises aframework, a mesh box, anchor ropes, an oxygen-increasing framework and a handle. A layer of oxygen-increasing framework is arranged at the lower part of the framework. The layer of oxygen-increasingframework is connected with the framework through the anchor ropes. The upper end of the mesh box is fixed on the framework through the anchor ropes. The framework and the layer of oxygen-increasingframework are both located in the interior of the mesh box. The framework comprises an upper framework and a lower framework. The layer of oxygen-increasing framework is located at the bottom. The lower framework is located above the layer of oxygen-increasing framework. The upper framework is located on the lower framework. The framework is equipped with the handle. The fry temporary rearing system can effectively reduce damage caused by fry capture and delivery, increase the survival rate and is operated easily and conveniently. The PVC pipes are good in anti-aging performance and excellentin freezing-proof performance. Pipe fittings are connected by PVC glue. The construction method is simple. Installation work efficiency is high. The overall system is low-weighted and easy to carry.
Description
technical field [0001] The invention relates to a fish fry temporary breeding system made of PVC pipes and a breeding method thereof, belonging to the technical field of aquaculture. Background technique [0002] The breeding of fish fry is an important part of aquaculture. Among them, the process of catching and releasing fish fry will cause great damage to the fry, resulting in a decrease in survival rate, which is an important factor restricting the efficiency of aquaculture. Therefore, it is necessary to invent a device for effectively temporarily raising fry, which can be used to temporarily raise fry. On the one hand, it is beneficial to links such as baiting and domestication, and on the other hand, it reduces the damage of mechanical operations to fry, thereby improving the quality of fry. survival rate. Traditionally, cement soil, earthen ponds or earthen pond fences are used for the temporary cultivation of fish fry. These methods occupy a large area, have high co...
