Distribution of Jasus spp. (Decapoda : Palinuridae) phyllosomas in southern waters: implications for larval recruitment
We sampled the distribution of mid- and late-stage (= advanced) Jasus group 'lalandii' rock lobster phyllosomas at 28 approximately equidistant stations across similar to 16 000 km of ocean between the west coast of Africa and the west coast of New Zealand to determine whether the larvae w...
