Abstract/Description: | Geostatistical method, which involved variogram and kriging, was applied to the geo-referenced catch and effort data collated from the logbook of five randomly selected vessels. Variogram analysis unraveled systematic spatial structure of catch rates of the species. No spatial dependence of catch rate was observed beyond the distance of 17.43 km. Kriging method predicted three regions of high, medium and low catch rates. Even though vessels’ logbook data was criticized for preferential sampling bias, we established here that application of geo-statistical tools to the same became useful in the present study. |
