GENETIC-STRUCTURE OF PENAEUS-MONODON IN AUSTRALIA - CONCORDANT RESULTS FROM MTDNA AND ALLOZYMES

Preliminary analyses of mtDNA restriction fragment length polymorphisms confirmed results, first revealed by allozyme surveys, that Australian P. monodon from the west coast differ genetically from cast coast populations. The levels of variation in the mtDNA were high relative to the allozymes. These data suggest mtDNA analyses will prove Useful in further describing P. monodon population structure, for example, in testing whether the distribution patterns of rare allozyme variants reflect differentiation on smaller geographical scales, or are the result of some stochastic effect.
