Water treatment unit for zebrafish culture system using brine shrimp for feeding

Abstract

The invention relates to a water treatment unit for a zebrafish culture system using brine shrimp for feeding. The water treatment unit comprises a water purification tank, a backflow water diverter and a sand filter. The water purification tank is divided into a filter chamber, a thermo-sterilization chamber and a feeding chamber by partitions. A submersible pump in the feeding chamber supplies feed to all culture units through pipelines. The backflow water diverter comprises a U-shaped pipe. A backflow pipe is connected to the bottom of the U-shaped pipe and leads to the feeding chamber of the water purification tank. One end of the U-shaped pipe is communicated with an overflow master pipe, and the other end of the U-shaped pipe is communicated with the filter chamber. The sand filter comprises a sand filtering pipe which is provided with a sand filtering tank and a self-priming pump. One end of the sand filtering pipe is communicated with the feeding chamber, and the other end of the sand filtering pipe is communicated with the filter chamber. The water treatment unit is simple in structure and simple to operate, and the feed can be supplied into the culture units without stopping water circulation. Therefore, heavy manual feeding of brine shrimp into the culture units one by one is avoided, and feeding amount of each culture unit can be controlled to prevent bait loss and increase utilization rate.

Description

technical field [0001] The invention relates to a model animal breeding and development device, in particular to a water treatment device for a zebrafish breeding system for feeding brine shrimp. Background technique [0002] Zebrafish is one of the commonly used model animals for developmental biology research. It has incomparable advantages: short generation cycle (about 2.5-3 months), rapid development, transparent embryos, easy to observe, large egg production, and It is currently the only vertebrate model that can carry out large-scale genetic mutation screening, and has become one of the best vertebrate developmental genetics research systems. Brine shrimp is rich in nutrients, can promote zebrafish spawning, and is suitable for hatching in salt water, and the hatched live brine shrimp is pure and free of parasites. Therefore, live brine shrimp is recognized as the best natural bait for zebrafish. [0003] In a large-scale zebrafish breeding system, there are often hu...

Problems solved by technology

The filter equipment is set to purify the circulating water in the zebrafish breeding system, and filter out the zebrafish excrement in the circulation pipe waterway to ensure the clean water quality. In this breeding system, the water circulation needs to be stopped when feeding the zebrafish. Stop the water circulation and feed brine shrimp, part of the brine shrimp will be eaten by zebrafish, and the other part will be transported to the filtration and sterilization equipment by the overflow collection pipeline, and will be lost after filtration and sterilization, resulting in waste of resources; it is also easy to block Filtration and purification devices will affect the normal operation of the entire system in severe cases
