Dietary value of benthic diatoms for the growth of post-larval abalone Haliotis discus hannai
The feeding behaviour and the growth of post-larval abalone (1–2 mm in shell length) Haliotis discus hannai fed on nine species of benthic diatom were examined in the laboratory. DigestionExpand

Radula development in abalone Haliotis discus hannai from larva to adult in relation to feeding transitions
The radula morphology of Haliotis discus hannai was examined by scanning elec- tron microscope from the larval to the adult stage. The radula of competent larvae contained 11-13 transverse rows ofExpand

Effects of elevated pCO2 on the early development of the commercially important gastropod, Ezo abalone Haliotis discus hannai
We used an up-to-date, a high accuracy CO2 manipulation system to investigate the sensitivity of organisms to CO2 acidification, rearing marine calcifiers under elevated CO2 in running water. WeExpand

Effects of ocean acidification on the early developmental stages of the horned turban, Turbo cornutus
To estimate the impact of CO2-driven ocean acidification on the early life stages of gastropods, the effects of increased partial pressure of seawater carbon dioxide (pCO2) (800–2,000 μatm) on theExpand

Survival and growth rates of post-larval abalone Haliotis discus hannai fed conspecific trail mucus and/or benthic diatom Cocconeis scutellum var. parva
Abstract The settlement rate and growth rate of post-larval Haliotis discus hannai were compared in the laboratory when raised on the following three experimental substrata. (1) Mucus: trail mucus ofExpand
