Species | Development state | Trait | Primary Data | Secondary Data |
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 | 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 | 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 |
Micropterus dolomieui | Larvae | Temperature during larval development | 17.2-19.5 observed temperature in natural conditions | 18.35 °C |
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 | Male | 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 | 22.35 years |
Micropterus dolomieui | Spawning conditions | Spawning season | Nest building geban on June 3 in 1965 and June 5 in 1966 | ['June'] |
Micropterus dolomieui | Spawning conditions | Spawning period duration | activity lasted for less than 1 week | 1.0 weeks |
Micropterus dolomieui | Spawning conditions | Spawning temperature | Nest building started when water temperatures was 15-18°C | 16.5 °C |
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 | 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 | Lithophils |
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 |
