Many workers have examined the processes influencing the recruitment of temperate marine invertebrates but comparatively little is kno'ivn about their tropical counterparts. Brachyuran crustaceans are important constituents of coral reefs, yet remain largely under-studied To examine the temporal patterns of tropical brachyuran larval abundances and postlarval settlement, we deployed 3 replicate...

Neoparamoeba spp. are amphizoic amoebae with the capacity to colonize the gills of some marine fish, causing amoebic gill disease (AGD). Here, the gill tissue transcriptome response of Atlantic salmon (Salmo salar L.) to AGD is described. Tanks housing Atlantic salmon were inoculated with Neoparamoeba spp. and fish sampled at time points up to 8 days post-inoculation (p.i.). Gill tissues were t...

Adaptations to salinity are reviewed throughout development in both species of the genus Homarus. Some populations of homarid lobsters are known to inhabit coastal and estuarine areas where salinity fluctuates. Salinity tolerance varies during development, with 50 % lethal salinities (LS(50)) ranging from approximately 15-17 in larvae to approximately 12 in postlarvae and 10 in adults. La...

The present investigation was focused on the effect of Bacillus megaterium enriched to Artemia nauplii and sprayed supplemented feed fed white shrimp Litopenaeus vannamei postlarvae (PL) obtain high survival growth. with different levels B. (5×107, 5×109 5×1011 cfu /mL) for a period 30 days. Similarly, probiotic PL time 15 Postlarvae cells (E2) produce better growth when compared that other con...

Histopathological effects of different sublethal concentrations (1, 2 and 4 mg/l) of diazinon, an organophosphorus pesticide, on gill, liver, spleen and kidney of grass carp (Ctenopharyngodon idella) were studied after 1, 7, 15, 30 and 45 days post-exposing fishes weighting 850 ± 155 g to the toxicant for 12 hours at 18-22ºC. In addition, tissues of nostril were examined for transmission electr...
