Factors affecting the food value of diatom strains for post-larval abalone Haliotis iris
The growth and survival of post-larval abalone Haliotis iris (mean initial shell length 570 μm) fed on eight strains (seven species) of benthic diatom were examined in the laboratory. Post-larvaeExpand

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

Importance of extracellular organic carbon production in the total primary production by tidal-flat diatoms in comparison to phytoplankton
Microphytobenthos, mainly benthic diatoms, produce mucilages containing extracellular polymeric substances (EPS) on the cell surface. The ratios of particulate organic carbon ( 14 C-POC) and totalExpand

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

EXTREMELY HIGH GROWTH RATE OF THE SMALL DIATOM CHAETOCEROS SALSUGINEUM ISOLATED FROM AN ESTUARY IN THE EASTERN SETO INLAND SEA, JAPAN 1
Small single‐celled Chaetoceros sp. are often widely distributed, but frequently overlooked. An estuarine diatom with an extremely high growth potential under optimal conditions was isolated from theExpand

FACTORS AFFECTING SETTLEMENT OF ABALONE (HALIOTIS IRIS) LARVAE ON BENTHIC DIATOM FILMS
Abstract Diatoms are widely used in abalone hatcheries to induce larval settlement (=attachment and metamorphosis) but there are few data on the factors that influence their effectiveness asExpand
