    Description: Weekly spawn and hatching rates of Clarias gariepinus and Heterbranchus longifilis were determined in earthen ponds during the rainy and dry seasons. There was a significant increase in spawn weight from the 2nd to the 7th week after stocking C. gariepinus brood fish (p〈0.05). In H. longifilis; the increase in spawn weight was significant from the 4th to the 9th weeks (P〈0.05). A positive correlation was found between spawn weight and female broodfish weight from the 4th to the 9th weeks for both species. The best hatching rates were obtained during the 7th week for C. gariepinus, and in the 8th week for H. longifilis. Rainy season trials gave better results in both species than in the dry season, while only C. gariepinus produced hatchable oocytes during dry season trials.

    Description: Previous studies by various agencies have shown that widespread erosion is occurring on the Nigerian shoreline and in some places, the rate of shoreline retreat is so rapid as to be alarming. Shoreline stabilisation methods adopted for combating erosion along our coasts have been counter-productive and, in many cases, aggravated the problem largely because such solutions had been, and are being, carried out without consideration or understanding of fundamental principles of shoreline dynamics and processes. Following a review of case histories, the Nigerian Institute for Oceanography and Marine Research initiated in September, 1981 a data acquisition programme aimed at making a scientific input into long term and large scale coastal management planing in Nigeria. This paper details the preliminary results and interpretations from on-going beach profiling and littoral environment observations at four selected erosion monitoring stations at Victoria Island, Forcados, Brass and Ibeno-Eket Beaches spanning the entire Nigerian coastline. State-of-the-art knowledge of coastal stabilisation and beach nourishment techniques are evaluated in the light of data presented in this work. Projected research efforts of the Institute along the Nigerian coastline are outlined and future national policy options suggested
