In males it is 1 year earlier. With constant temperature-controlled warm water husbandry at Ahrensburg it was possible for fish to attain sexual maturity very much earlier. Female carp produced fertile eggs at 15 months and males were fertile as early as 3 months of age. In this installation Celikkale (1976) obtained fertile eggs from females at age 11 months and 9 days. Gupta (1975) investigated the histology of gonad development in carp raised from eggs at Ahrensburg at 23°C and described six distinct stages to maturity.

A single pipe would simply drain the overflow without having a cleaning effect. ~ other. The outer pipe is longer than the inner pipe and rests on spacers which form a gap at the bottom through which sediment is sucked up to the drain-away over the top of the inner and shorter pipe. Draining is continuous but suction is not as strong as in the Steinberg system. However in tanks with very high stock density a single overflow pipe may be sufficient because the constant movement of the fish tends to keep solids in suspension.

4. THE DEVELOPMENT OF NEW TECHNIQUES FOR AQUACULTURE ENVIRONMENT CONTROLLED W A R M W A T E R AQUACULTURE Chapter 2 summarized the various methods used in aquaculture, ranging from practices dating back to ancient times to the more recent and technically sophisticated. Chapter 3 surveyed the specific way in which particular species were exploited by practical aquaculture. This chapter deals with the research and development in environment controlled warm water fish farming, which has been carried out at the Ahrensburg Fish Research Institute near Hamburg since 1965.
