Abstract:
Seasonal variation and potential output of egg liberation in the fucalean species Hormosira banksii (Turner). Decaisne was investigatedb Eggs were produced throughout the year but the reproductive capacity was seasonal. A good liberation of was observed from July-October (winter to early spring) when the mean sea water temperature was 14 C where eggs produced were healthy, morphologically as well as physiologically and fertilization in the laboratory showed a high synchrony. Liberation of eg» was low at high temperature (17.5-220C) during December-February and most of the eggs were apparently not healthy often disintegrated when released from the conceptacles and viability of the eggs was also low with abnormal growth.
