Question

To be or not to be? Male and/or female... Marine fish and invertebrates use a variety of reproductive life history strategies to maximize fitness, which is the contribution their offspring make to the future population. Speaking from the viewpoint of your favorite coral reef fish, write a journal log detailing your behavior, appearance, and sexual status over time. The journal entries should illustrate how the reproductive life history strategy that you use works.

Answer 1

Large variety of marine invertibrates and fishes begin life with a planktonic larva stage. Ciral reef fish larva often span week to month in pelazic realm before setteling back to the reef as new recruit. Survival and dispersal during vulnerable planktonic stage will influence population connectivityas well as production and viability of adult populations. Self recruitment is crucial for the replenishment of reef fish population that are not likely to recessive recruit from other population.

Returing of fish to reef after spending time in plankton can be influence by biological such as birth date, larva morphology and palazic larval duration as well as environment factor such tempreture, food avability, & current. Interaction between larva biology and physical environment cause variation in settlement and recruitment and ultimaely influence resulting adult population.
