Growth and survival of juvenile greenlip abalone (Haliotis laevigata) feeding on germlings of the macroalgae ulva sp.

ABSTRACT Germlings of the green alga Ulva sp. were developed as a diet for juvenile Haliotis laevigata ([greater than or equal to]3.5 mm shell length) and compared with a current commercial diet consisting of Ulvella lens plus the diatom species Navicula cf. jeffreyi. The utilization of macroalgae germlings (juvenile gametophyte and sporophyte) allowed 3-dimensional growth and subsequently provided greater feed biomass in comparison with the current 2-dimensional commercial feed for the later nursery phase consisting of 5-10 mm (shell length) juvenile abalone. The juvenile abalone ...
