Abstract

A widely held belief that climate has impact on fish landing and leads us to find out how these effects contribute the abundance and diversity of fishes in Kota Kinabalu based upon monsoonal period. Correlation of abundance and diversity of fishes in pelagic environment with rainfall, temperature and SOI values suggest that the fish landing is believed to be subtly sensitive to the effects of climate. Result Indicated that correlation coefficient between rainfall and fish landings is +0.60 with rainfall leading by 2 months. Also, fish landings and temperature are correlated with correlation coefficient of +0.76 with temperature leading by 3 months. However, a negative correlation of -0.83 between SOI values on fish landings is observed whereby 2 months before fish landings increase, the SOI values become low or negative. Abundance and diversity of fish landing time series for Kota Kinabalu have been studied using available local data for the last 11 years. Results indicate that the highest abundance of fish landing was in 2007 with 42974.43 metric tons with 11 major species. In contrast, 27396.97 metric tons in 2009 with 8 major species is the lowest abundance of fish landings during the study periods. In terms of monsoonal aspect, the Southwest monsoon has recorded the highest average abundance with 4969.14 metric tons with 10 major species of fishes. During monsoonal period, Northeast monsoon and Inter seasonal monsoon are both recorded 3365.12 metric tons with 10 major species and 3151.57 metric tons with 9 major species respectively. The findings draw attention to the abundance and diversity of fishes that are low during Interseasonal monsoon period. The prominent fish species are Ilisha elongata, Nemipteros sp. and Sardinella albella. By understanding the changes in SOI values and meteorological parameters such as rainfall, winds and temperature, preparations can be made to promote sustainable fisheries development in the Sabah fishery sector.
