Semelparous fish species-oncorhynchus bistwobe

Assignment Help Biology
Reference no: EM132526420

The semelparous fish species, Oncorhynchus bistwobe, is a new major target of fishing. There are two genetically distinct life-history morphs of this species. One morph matures at seven years of age and produces on average 4000 eggs per individual during spawning. The other morph matures at six years of age and produces on average 1000 eggs per individual during spawning.

Assume that in the absence of fishing, the survivorship of both morphs to age 6 is identical and individuals are only harvested between ages 6 and 7. Use a life table approach to predict the minimum level of harvest mortality that will result in natural selection favoring the morph that matures at 6 years.
