Description

A water-saving fish fry breeding pond

technical field

The utility model relates to a fish pond, in particular to a water-saving fry culture pond.

Background technique

Fry culture of prior art often carries out in common pond. Fish eggs in water, like eggs on land, are rich in nutrients and can easily become the bait of many aquatic animals, and are vulnerable to attack and damage. For example, small fish and shrimps in the water are the main killers of fish eggs, and even various insects in the water, Daphnia daphnia and other large zooplankton can harm fish eggs. Therefore, pay attention to eliminating the predators of fish eggs. Strictly clear the pond and filter it when entering the water. Keep the water rich in oxygen during the hatching process. Embryos need to breathe oxygen during development, a large amount of oxygen is needed after the emergence of tail buds, and even more oxygen is needed in the larvae stage. Regardless of indoor dry hatching or outdoor pool hatching, attention must be paid to supplying sufficient oxygen. When hatching in the pool, it is best to increase the micro-flow water, stimulate the fish nest, and increase the oxygen in the running water. However, traditional ponds cannot meet these requirements, resulting in excessive water use and difficulty in fish fry breeding.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a water-saving fish fry culture pond that saves labor and time, is low in cost, saves water, and is pollution-free.

The purpose of this utility model is achieved through the following technical solutions. A water-saving fish fry breeding pond mainly includes a fish egg hatching area, a fish fry area, and an adult fish area. The fish egg hatching area is a rectangular ditch, and the fish egg hatching area is separated from the fish fry area by a ditch wall. The water inlet pipe is connected, the water outlet of the egg hatching area is connected with the water inlet of the fish fry area, the fish fry area is an S-shaped ditch, the adult fish area is composed of at least one fish pond, the water outlet of the fry area is connected with the water inlet of the fish pond, and the fish pond is equipped with drain.

As a preference: the water outlets of the fry area, fish egg hatching area and adult fish area are all equipped with trash racks.

The beneficial effects of the utility model are: providing the fry with a growth environment close to the original ecology, which is beneficial to their habitat, reproduction and growth; the water in the pool is "one in and one out", which not only saves water, but also concentrates the water volume and has a good sewage discharge effect; reduces the number of management personnel Labor intensity, saving manpower and material resources.
