| dc.description.abstract | A Generalized Linear Mixed Model (GLMM) has been applied to the Area 8 bakkie CPUE data. The intention was to include data from Areas 10, 11 and East of Hangklip (Areas 12-14) in the analyses and to include subarea as a factor in the model, but preliminary results indicated that extending to these other Areas did not produce satisfactory results within a random-effects framework. This paper therefore reports standardized indices of abundance for the bakkie fishery from Area 8 only, including sub-area as an effect in the model. A procedure has been adopted to adjust the standardized index to allow for the movement of lobster into the East of Hangklip area over a period of time (1987-1995). The index is then extended back to 1986 by scaling the pre-1992 indices from the model applied in the past to standardize the Area 8 CPUE data, so that they can be incorporated with the GLMM-based index. | en_ZA |
