Species Development state Trait Primary Data Secondary Data
Morone saxatilis Spawning conditions Mating system Spawning can involve multiple males and more than one female, but it is characterized by one female and many males releasing gametes at the water surface [Once a group of males has spawned, they will continue to chase the spent female or court the next available one] Ambiguous
Morone saxatilis Spawning conditions Nycthemeral period of oviposition It remains unclear whether spawning occurs predominantly during the day or the night Ambiguous
Morone saxatilis Spawning conditions Spawning temperature Around 16-17 16.5 °C
Morone saxatilis Spawning conditions Spawning period duration Males remain on the spawning grounds for as long as 30 days while females spend about 7-10 days there 8.5 weeks
Morone saxatilis Spawning conditions Spawning depth Release gametes at the water surface No data
Morone saxatilis Female Age at sexual maturity 3 [Male] 3.0 years
Morone saxatilis Female Onset of oogenesis Vitellogenesis may be initiated as early as late-September, but this could vary ['September']
Morone saxatilis Female Intensifying oogenesis activity There is a surge in oocyte growth and circulating levels of sex steroids around the vernal equinox No data
Morone americana Female Oocyte development Group-synchronous, multiple clutch [Simultaneously recruit several batches of oocytes for repeated spawing events during a brief annual spawning season] Ambiguous
Morone chrysops Female Oocyte development Group-synchronous, multiple clutch [Simultaneously recriut several batches of oocytes for repeated spawing events during a brief annual spawning season] Ambiguous
Morone saxatilis Female Oocyte development Group-synchronous type, single clutch [One clutch of oocytes is recruited through development, maturation, and ovulation for the single annual spawning] Group-synchronous
Morone saxatilis Spawning conditions Spawning season Occurs primarily in April and May ['April', 'May']
Morone saxatilis Larvae Temperature during larval development 16-17 is around the optimal for larval development and survival 16.5 °C
Morone saxatilis Female Age at sexual maturity 3-5 4.0 year
Morone saxatilis Spawning conditions Spawning release Once, single clutch. Females releases one long continuous cloud of eggs for less than ten seconds, sometimes another (minor) synchronous gamete release can be observed No category
