Micropterus dolomieui Spawning conditions Parental care There was no obvious explanation of why some nests failed and were deserted by the guarding male No category
Micropterus dolomieui Spawning conditions Spawning substrate Nest were constructed typically on sand and gravel. When adequate gravel was not available, the bottom of the concave bowl of each nest was usually covered with woody debris or broken clam shells, or both Ambiguous
Micropterus dolomieui Spawning conditions Spawning temperature Nest building started when water temperatures was 15-18°C 16.5 °C
Micropterus dolomieui Spawning conditions Spawning period duration activity lasted for less than 1 week 1.0 weeks
Micropterus dolomieui Spawning conditions Spawning water type At a distance of 0.3-2.4 m from the leeward shore. Small lakes with controlled water levels may provide thermal and other environmental conditions suitable for natural reproduction Stagnant water
Micropterus dolomieui Spawning conditions Spawning depth At wa water depth of 0.6-1.2 0.9 m
Micropterus dolomieui Egg Incubation time Egg incubation asted 4 days at water temperatures ranging between 15.2 and 18.2°C in natural conditions) 4.0 days
Micropterus dolomieui Female Age at sexual maturity Bass of both sexes began to mature at age IV (18.7-26.0 cm) with 33% of the males and 9.1% of the fremales mature. Of fish of age V, 88% of males and 82% of females were mature. All fish of age VI (26.4-36.6 cm) examined were mature 4.0 years
Micropterus dolomieui Egg Temperature for incubation Water temperatures observed in different lakes during incubation: 15.2-18.2, 16.7-20.0, 18.1-21.1 16.7 °C
Micropterus dolomieui Spawning conditions Spawning season Nest building geban on June 3 in 1965 and June 5 in 1966 ['June']

Micropterus dolomieui Larvae Full yolk-sac resorption 160 [Postlarval bass, rose off the nests in 1966 at 8-11 days after hatching, between June 17 and 20, when water temperatures ranged between 17.2 and 19.5°C] 9.5 °C * day
Micropterus dolomieui Larvae Larvae behaviour After rising from the nest, the young free-swimming bass remained in a dense mass close to the bottom and directly over the nest. Demersal
