Abstract
Previous chapters describe the effects that environmental factors have on the survival, growth and reproduction of individual fish. This chapter explores the changes in the abundance and total weight of fish in a population that result from these effects. Fishes have high fecundities (see Chapter 7) so the potential lifetime production of offspring is high. Although fish populations vary in abundance (Fig. 10.1) (Cushing, 1982; Rothschild, 1986), increases in abundance are usually several orders of magnitude lower than the potential maximum increase. Even when a population is increasing, the fate of most zygotes is to die before growing to sexual maturity.
