Fish survivorship varies by species. Type I species, like Atlantic herring and Pacific herring, have high early survival rates that change little later in life. Environmental factors, including climate warming, affect survival. Predatory fish, such as Chinook and coho trout, face high mortality rates from fishing practices like catch and release. Additionally, angler practices contribute … Read more
Not all fish have Type III survivorship. This pattern features high mortality in young fish and low death rates in adults. Many fish species, like salmon and trout, fit this model. They produce many offspring, but only a few survive to maturity. This strategy improves their chances of reproductive success in changing environments. R-selection species … Read more
