Alosa sapidissima | Egg | Degree-days for incubation | 130-150 [12-15 days at 12°C] | 140.0 °C * day |
Alosa sapidissima | Larvae | Larvae behaviour | Both feeding and yolksac larvae are planktonic [Dispersal therefore occurs by passive transport] | Demersal |
Alosa sapidissima | Larvae | Temperature during larval development | Rearead at 17°C | 17.0 °C |

Alosa sapidissima | Spawning conditions | Spawning migration period | Adults move into the Hudson River from Atlantic waters in early spring, usually begin in March and April, and temperature must be 12°C or above before the shad begin their run | ['March', 'April', 'May', 'June'] |

Alosa sapidissima | Spawning conditions | Nycthemeral period of oviposition | Mainly at night | Night |
Micropterus salmoides | Egg | Egg adhesiveness | Adhesive | Adhesive |
Micropterus salmoides | Spawning conditions | Spawning migration distance | Nonmigratory species | No data |
Micropterus salmoides | Spawning conditions | Parental care | Male guards the nests, even after the eggs have hatched | Male parental care |
Morone americana | Egg | Egg Buoyancy | Demersal | Demersal |
Morone americana | Egg | Egg adhesiveness | Adhesive | Adhesive |
Morone americana | Egg | Incubation time | 1.5-2.0 | 1.75 days |
Morone americana | Female | Age at sexual maturity | 5 in females | 5.0 year |
Morone americana | Male | Age at sexual maturity | 4 in males | 4.0 years |
Morone americana | Spawning conditions | Spawning migration period | Nonmigratory | No data |
Morone americana | Spawning conditions | Spawning season | From April to June, or July, with peak egg deposition in mid-May to early June | ['April', 'May', 'June', 'July'] |
Morone americana | Spawning conditions | Spawning water type | Tales place mainly in a variety of protected habitats, such as shallow flats, embayments, and tidal creeks | No category |
Morone saxatilis | Egg | Egg Buoyancy | Semibuoyant | Pelagic |
Morone saxatilis | Larvae | Full yolk-sac resorption | The yolk sas larval stage runs 3-6 days | 4.5 °C * day |
Morone saxatilis | Spawning conditions | Spawning season | Early May to June | ['May', 'June'] |
