| how many offspring an organism is able to produce |
|
|
Term
|
Definition
| more difficult to determine than female fecundity because it has to be studied in the wild or in a lab. Studying male fecundity in the wild is difficult to follow and hard to validate. Studying male fecundity in a lab is also difficult because the environment of the lab could affect fertilization rates, etc. |

Term
|
Definition
| All eggs to be spawned are in ovary prior to spawning. |
|
|
Term
|
Definition
| Eggs to be spawned are not all present in ovary before spawning, some are continuing to develop. |
|
|
Term
| Annual Potential Fecundity |
|
Definition
| Total number of advanced yolked oocytes that are matured per female each year (atretic losses not taken into account). |
|
|
Term
| Annual Realized Fecundity |
|
Definition
| Total number of eggs actually released per female per year. Equal to or lower than potential fecundity since some of the eggs can be reabsorbed through atresia during spawning, or some eggs may not be able to be liberating and remain in the ovary to be reabsorbed. |
|
|
Term
| Annual Population Fecundity |
|
Definition
| Total number of eggs a population produces in a breeding season. |
|
|
Term
|
Definition
| Total number of vitellogenic or advanced yolked oocytes at any time in the ovary. |
|
|
Term
|
Definition
| All developed oocytes are released at one time or over a short period of time but part of a single event. |
|
|
Term
|
Definition
| Eggs released in batches during a spawning period that usually lasts weeks or months. One portion of yolked oocytes selected for spawning and hydration in each batch. |
|
|
Term
|
Definition
| All formed oocytes are grown and ovulated from ovary development at the same time. No replenishment of one stage by an earlier stage. |
|
|
Term
| Group-Synchronous Development |
|
Definition
| At least two groups of oocytes are distinguished in maturing ovary (Larger oocytes (clutch) and smaller oocytes from which clutch is recruited). Larger oocytes are to be spawned during current breeding season; smaller oocytes are to be spawned in future breeding seasons. |
|
|
Term
| Asynchronous Ovary Development |
|
Definition
| Ovary contains random mixture of oocytes from all different stages. |
