10 Questions
What is the difference between synchronous and asynchronous fish reproduction?
Synchronous fish reproduce only once each year or once in their lifetime, while asynchronous fish are capable of ovulating on a regular basis, sometimes every day, over a prolonged period.
What are the types of reproduction mentioned in the text?
parthenogenesis, sexual reproduction, hermaphroditic reproduction
What are the three categories of breeding opportunities for fish mentioned in the text?
Synchronous, Group synchronous, Asynchronous
What is the variation in time of spawning and duration/season of reproduction among different fish species?
It varies between different species.
How does the size and age at first maturation vary for fish in different conditions?
The maturity age of the same species varies widely under different geographical and ecological conditions. In the same region, maturity age varies somewhat with ecological conditions and other intrinsic factors. Induced breed species reared in pond culture practice mature earlier than the natural riverine stock. Generally, males mature a little earlier than females.
Which fish species is an example of synchronous reproduction?
Salmonids
What distinguishes group synchronous fish from synchronous fish?
They have two or more distinct populations of oocytes present at the same time
What factor contributes to the variation in maturity age of fish in the same region?
Ecological conditions
Which fish is capable of ovulating on a regular basis, sometimes every day, over a prolonged period?
Zebrafish
What is the general trend regarding the maturity of male and female fish?
Males mature little earlier than females
