Associated characteristics


Species Development state Trait Primary Data Secondary Data
Morone americana Egg Egg size after water-hardening 0.80-0.86 [Swollen eggs] 0.83 mm
Morone americana Egg Incubation time 24 hours at 15.6-20°C to 144 hours at 11.1-15.6°C 17.8 days
Morone americana Egg Temperature for incubation Optimal temperature for hatch was 14.1°C and for larva length 17.6°C [Eggs incubated at 8°C did not hatch within 8 days, early embryo development appeared to be normal although slower than at 10 and 12°C. Eggs icubated at higher temperatures (20-26°c) developed rapidly ar first, but most died at the early gastrula to early-embryo stage] 23.0 °C
Morone americana Egg Degree-days for incubation [24 hours at 15.6-20°C to 144 hours at 11.1-15.6°C] 17.8 °C * day
Morone americana Larvae Initial larval size From mean of 2.13 to 2.86 [Depending on different salinities and temperatures] 2.13 mm
Morone americana Spawning conditions Spawning temperature Spawning temperatures of with perch range falls from 10 to 25.0°C, generally starts at 14.4°C, peaks at 15.6 to 19.4°C, and ends at 21.1 to 22.2°C 10.0 °C
