| Description: | To collect nauplii, shut airline valve and disconnect hose from pump. Shine a lamp on the bottom of the hatchery and wait until egg shells have floated and nauplii have gathered at the bottom. Then, move the air hose below water level and open the valve to drain nauplii through a brine shrimp net. Afterwards, close the valve, loop the hose over the top, reconnect to the pump, and open the valve again to resume aeration. |
