A STUDY ON THE REPRODUCTION CURVE AND REGULATION MEASURES ON THE DONG HAI POPULATION OF HAIRTLILS(TRICHIURUS HAUMELA FORSKAL)

Recently, reproductive mechanism have been widely used in studying fish population dynamies,In this report, the reproduction curve is plotted by the formula R=1525Ac on the hairtails in the Dong Hai, although numbers, parent and offspring, described here are in relative index instead of absolute number, The theoretical value of the reproductive relation obtained from the formula of the reproduction curve is treated by the mathematical model in stationary state from the known parameter of hairtails mentioned above.
