These livestock storage include incubators (where eggs are fertilized and allowed to hatch), larval tanks (slightly larger tanks where the larvae are grown), circular tanks (last stage before fish leave the onshore facility, where metamorphosis occurs), and storage tanks where the fish can be temporarily stored as they are transported from ...
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds.

The eggs are generally surrounded by the extraembryonic membranes but do not develop a shell, hard or soft, around these membranes. Some fish have thick, leathery coats, especially if ...

The female then extrudes eggs, which pass through the spermatophores. The female carries the fertilized eggs with her until they hatch; the time may vary, but is generally less than three weeks. A large female may lay up to 100,000 eggs. From these eggs hatch zoeae, the first larval stage of crustaceans. They drift towards brackish waters where ...
