The temporal variation of shrimp landings over 16-year (2000-2015) and the long-term trend of meteorological parameters in Kota Kinabalu were examined. The correlation between the abundance and diversity of shrimp landing with meteorological parameters (temperature, rainfall, relative humidity, wind speed), as well as the Southern Oscillation Index (SOI), were also interpreted in the study. Results indicate that the highest shrimp landings in Kota Kinabalu were in 2000 with 735.9 tonnes, while the lowest was in 2012 with 195.4 tonnes. The dominant shrimp species during the study period was sand shrimp (Metapenaeopsis barbata). There were minor changes in the trend of meteorological parameters with a gradient rate of +0.03 for temperature, -0.02 for rainfall, and -0.01 for relative humidity and wind speed per year in Kota Kinabalu. Results indicated that shrimp landings were positively significant with precipitation and relative humidity with correlation coefficients of 0.308 and 0.219. Results also showed shrimp landings were negatively important with temperature, r = -0.161, P < 0.026. However, there was no correlation between shrimp landings with wind speed and SOI with a correlation coefficient of 0.057, P >0.583 and -0.123 P >0.090. The consequence of fluctuations of meteorological parameters may affect the marine species, affecting the fisheries economics in Kota Kinabalu.
