The settlement, early growth and survival of the larval abalone Haliotis discus hannai in response to eight monospecific benthic diatoms were examined in the laboratory. Postlarvae showed active settling and feeding behaviour in all diatom species and in naturally occurring diatoms. Larval settlement rates differed significantly between experimental substrata after 24 h and 48 h. Nitzschia sp. (96.67 %), Hantzschia amphioxys var. leptocephala (95.00 %) and Navicula seminulum (90.00 %) strongly… 

The effects of different monospecific benthic diatoms on larval settlement, metamorphosis, survival, and growth of Haliotis asinina Linnaeus in the South China Sea

Commercial nursery slats seeded with N. alexandria will result in high and consistent settlement, metamorphosis, and survival, while slats with A. coffeaeformis will ensure sufficient food for rapid growth of the H. asinina post-larvae.

Grazing periodicity, grazing rate, feeding preference, and gut examination of early juveniles of abalone Haliotis asinina–fed five benthic diatom species

This study evaluated the suitability of five diatom species (Amphora sp., Cocconeis sp., Navicula ramosissima, Nitzschia sp., and Tryblionella sp.) as food to abalone Haliotis asinina early juveniles

Effect of the concentrated-diatom of Caloneis schroederi and Rhaphoneis sp. for seedling production of Haliotis discus hannai

It is suggested that C. schroederi is proper for settlement of the larvae and Rhaphoneis sp.

Diatom diet selectivity by early post-larval abalone Haliotis diversicolor supertexta under hatchery conditions

Nano-diatoms (<20 μm in length) accounted for a considerable proportion of the total species number and cell density of the diatom assemblages in the gut contents and on the films, which suggests that nano-Diatoms are important to the efficient production of abalone seed.

북방전복 종묘생산을 위한 농축 규조류 Caloneis schroederi와 Rhaphoneis sp.의 효과

It is suggested that C. schroederi is proper for settlement of the larvae and Rhaphoneis sp.

Beneficial effects of benthic diatoms on growth and physiological performance in juvenile sea cucumber Apostichopus japonicus (Selenka)

Benthic diatoms are considered a key dietary component, particularly for early juvenile sea cucumber. Physiological effects of benthic diatoms on growth of juvenile sea cucumber Apostichopus

Metamorphosis induction of the dog conch Strombus canarium (Gastropoda: Strombidae) using cues associated with conch nursery habitat.

The meetamorphosis response of Strombus canarium larvae to various metamorphosis cues associated with conch nursery habitat and to KCl and GABA, were tested and the use of KCl was suggested for application in hatchery spat production of the species.

Investigations on the growth kinetics of hantzschia amphioxys homa lagoon by izmir bay (Aegean Sea)

zschia amphioxys were investigated under continuous-light period and batch culture conditions. The optimum temperature and light intensities were found as 18°C and 52 μmol/ms (saturasyon light),

Effects of light quality and intensity on the growth, survival and metamorphosis of Haliotis discus hannai Ino larvae

Light is a key environmental factor that influences the growth, culture and survival of aquatic organisms. This study examined the effects of different light qualities (red, orange, white, blue and



Settlement, early growth and survival of Haliotis rubra in response to different algal species

Commercial nursery plates seeded with U. lens will result in high and consistent settlement, while an inoculum with Navicula sp.


This work evaluated the growth of red abalone postlarvae fed with Navicula incerta, Amphiprora paludosa var.

Analysis of Feeding and Growth Rate of Newly Metamorphosed Abalone Haliotis discus hannai Fed on Four Species of Benthic Diatom

The feeding ecology of post-larval and juvenile abalone below the size at which they can consume macroalgae has received little attention.1-5) Although benthic diatoms have been considered the

Effects of Benthic Diatoms on Settlement and Metamorphosis of Abalone Larvae

The settlement and metamorphosis of veliger larvae of abalone, Haliotis discus hannai, were observed in chambers covered with monocultured benthic diatoms on the bottom surface and a large number of larvae settled on three-dimensional diatom communities died before metamorphotic.

Diatom diet of abalone post-larvae (Haliotis midae) and the effect of pre-grazing the diatom overstorey

Results indicated that abalone post-larvae preferred prostrate diatoms but would consume the more loosely packed, overstorey species such as Delphineis karstenii (Boden) Fryxell if their preferred food was not available.
