[40] [18] The bigmouth buffalo is a spring spawner generally spawning between April and June [6] when the water temperature is between 13 and 26 °C (55 and 79 °F), but may skip spawning if water-level fluctuations are not adequate. [3] [5] The bigmouth buffalo is a broadcaster that has adhesive eggs, which it lays in vegetated waters.
Most commonly they involve sudden changes in the environment, such as changes in temperature, salinity, and/or the abundance of food. Catfish of the genus Corydoras, for example, spawn immediately after heavy rain, the specific cues being an increase in water level and a decrease in temperature. When water levels rise, it allows many fish ...
A member of the Cyprinidae, carp spawn in times between April and August, largely dependent upon the climate and conditions they live in. Oxygen levels of the water, availability of food, size of each fish, age, number of times the fish has spawned before and water temperature are all factors known to effect when and how many eggs each carp ...
The spawn (eggs) of a clownfish.The black spots are the developing eyes. Spawn is the eggs and sperm released or deposited into water by aquatic animals.As a verb, to spawn refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning.
The eggs usually hatch in 8–10 days, but can take up to 21 days depending on temperature and proper spawning habitat. Yellow perch do not travel far during the year, but move into deeper water during winter and return to shallow water in spring to spawn. Spawning occurs in the spring when water temperatures are between 6.7 and 12.8 °C.
Spawning season for bluegills starts late in May and extends into August. The peak of the spawning season usually occurs in June in waters of 67 to 80 °F (19 to 27 °C). The male bluegills arrive first at the mating site. They will make a spawning bed of six to 12 inches in diameter in shallow water, clustering as many as 50 beds together.
All species of tuna are reported to spawn in water temperatures above 24 °C (75 °F). [29] However, 24 °C (75 °F) is outside, or at the upper limit, of temperature tolerances for bluefin tunas. Large individuals have been found to withstand temperatures of less than 10 °C (50 °F) and as low as 7 °C (45 °F) for over 10 hours, possibly to ...
The fish spawn during the early spring to the late fall, from March to November. Peak spawning occurs during May to September in Mid-Atlantic Bight [Note 2] regions, differences in temperatures affect the breeding time. In U.S waters further south, the spawning season occurs from April to June. Males grow faster and reach larger sizes than females.
