Most British Columbia herring begin sexual maturation in the late summer and become sexually mature in the subsequent March or April. As they mature, most stocks migrate from summer feeding grounds to overwintering areas and then to shallow nearshore spawning areas. Also, newly recruited, sexually maturing fish join the adult spawning stocks, either on the summer or winter grounds. These events occur in an unpredictable environment. Consequently, reproduction in Pacific herring (Clupea harengus pallasi) may be viewed as a biological problem of maintaining synchrony and precision: specifically the synchronous maturation of (1) males and females and (2) the recruit spawners with the adult fish that have spawned in previous years. Biological precision is required to ensure that gametes are released at the correct place at the correct time. Further precision is required to achieve an appropriate balance between egg number and egg size, and then to control the density of eggs deposited on the bottom. The annua...
