Hatching troughs are usually made of sheets of aluminium or stainless steel; their dimensions vary, but they are segmented by partitions across the middle, each segment having a drain and an inlet pipe. The segments make it possible to separate eggs in different stages of development. The eggs are kept in 7. 5 cm deep baskets, made of 0. 6 cm meshed hardware cloth and suspended by wire from the side of the trough, so that the water line is below the top of the basket.... Six to ten days are required for catfish eggs to hatch... 2, record 1, English, - hatching%20trough

At hatching the [fish] sac fry are golden and fall through the egg basket and school in a tight cluster on the bottom of the tank. Sac fry do not need to be fed because they receive nourishment from the attached yolk sac. If a... fry-rearing trough is used, the sac fry are siphoned into a bucket using a [half-inch] hose and then transferred to the rearing trough. The yolk sac is absorbed by the fry in about 3 to 5 days, depending on water temperature. 1, record 2, English, - fry%2Drearing%20trough
