Question

The Blue Catfish spawns (lays eggs) in river water at 21-23 degrees Celsius, but the pool where they spawn

is currently at a temperature of 18 degrees celsius. Design a heat-regulation device.

criteria: what does your device need to do? how will you measure its success?

constriants: how will you minimize the impacy on the river environment (you cant just pour chemicals straight into the river)

Answer 1

thank you the person above

Answer 2

Our major catfish species spawn during spring or summer when the water warms to an optimal temperature. Channel and blue catfish spawn at 70-84 degrees, but 80-81 degrees is considered best. Flatheads spawn at 66-75 degrees. Catfish spawning begins at different times in different latitudes, progressing from south to north.
