Inside the Golden Perch |
The Breeding The spawning takes place in between April and May. ( it depends on the size and metrety.) For laying the eggs the female glides over the top of the water plants with all her fins lowered, shedding the eggs which are being fertilized by one or 2 males. A large Female can lay up to 500,00 eggs in one batch. A small female can lay up to 200,000 eggs They start to hatch about 18 days or only 8-10 days if the weather is warm. The transparent larvae are 1 in 5 in length. After the hatching has happened the larvae spirals to the waters surface to fill his/she's air-bladder. They only do so after lying around the water plants for a while. Perches normally mature at the age of 3. But the longest recorded was the age of 10 and a half years of age |
