How do they reproduce?

Reproduction is one of the most interesting characteristics of the longear sunfish. The males are ones that make elaborate nests, and the species is known for spawning in groups.

A breeding female prefers males with a longer opercular flap. As the females enter a nesting colony, the males become a guide by opening up their fins to take the female towards the nest. After the mating ritual, both the longear males and the females release the gametes at the same time after shuddering.

Females can lay up to 140-2800 or more eggs depending on the location. The spawning event of longears takes place in shallow streams and waterbodies.

Males end the hospitality for the females after the eggs have been laid in the nest. The father is keen on keeping his nest as safe as possible, and its first instinct is to fan the nest with the paired and caudal fins.

It might help in better fertilization of eggs. Another interesting point is the construction of the nest, which is mainly done by the male fish when it flaps the tail fins vigorously to create a depression in the bottom substrate.

Apart from the dominant males with large ears, the nesting colonies also contain the sneaker male and the satellite male.

These sneaky fishes slyly get into the nests to release their sperms on top of the eggs. The eggs present in the nests only take two to seven days to hatch, giving rise to the small fry.

What is their conservation status?
