Artificiаl Selectiоn in Shrimp Aquаculture Suppоse yоu аre a shrimp farmer and you aim to produce populations of shrimp with higher rates of production. To do this, you plan to selectively breed female shrimp that have certain reproductive traits. Use the table of research data below and your knowledge of selection and evolution to answer the following question. Female reproductive traits and their associated levels of heritability (range 0-1) and correlation with individual reproductive success (range 0-1). A “spawn” is when a female lays eggs and a female can spawn multiple times per season. (Adapted from Ibarra et al. 2007.) Female Trait Heritability Correlation with Reproductive Success Number of spawns 0.20 0.77 Days to first spawn 0.54 0.56 Egg protein 0.47 0.32 Number of eggs 0.17 0.56 Egg diameter 0.07 0.10 Ovary maturity at first spawn 0.71 0.65 Which one trait from the table would be the most effective target for artificial selection towards shrimp populations with higher rates of production? That is, if you measured just one trait and selected shrimp based upon it, which one trait would you pick? Explain your choice and reasoning. Focus on the process of evolution and selection.
