Have No Fear - Retrofit for Re-use in your hatchery!

摘要

Water, water everywhere? Not so! We are learning about water shortages and water quality problems from every industry these days, aquaculture included. Decreasing availability of water, and progressively stringent discharge regulations make it increasingly important to control and regulate the supply and discharge of hatchery water. Surprisingly, in aquaculture facilities generally, flow-through technology is still the most common strategy, but water re-use is quickly becoming popular since less water is required, or productivity can be increased. It is not difficult to convert a flow-through hatchery to partial re-use: not a lot of equipment is required and it can be retrofitted in most hatcheries to both raceways and circular tank layouts.
