What triggers fish to spawn?
by
Spawning triggers are environmental cues that cause marine animals to breed. Most commonly they involve sudden changes in the environment, such as changes in temperature, salinity, and the abundance of food.
Fish spawning occurs when the temperatures in your pond reach 50º-70º. It may be a sunny warm spring day with the temperatures reaching the 80º mark, but unless the pond temperatures are between 50º-70º, spawning won’t happen.
How do you know when fish are spawning?
Spawning phase: Overies are very much enlarged, occupying the entire body cavity.They are turgid and yellow in colour with a large number of translucent eggs. Ovarian wall is very thin, almost transparent. Eggs are present in the oviduct also, and the fish spawns a number of times during this period.
While the time from initial fertilization to the fry stage usually takes about 105 days, the time varies depending on species and water temperature.

Do dead fishes drown?
Most fish are slightly denser than water, so sink immediately after death. However, like a drowned human, they become more buoyant over time as bacterial decomposition produces gases inside the body. Usually, enough gas builds up in body cavities to make the corpse float, like an inflated balloon.
