Abstract Zooplanktivory is an important source of nutrients in corals, providing up to 35% daily metabolic energy requirements some species. However, little known about coral zooplanktivory shortly after larval settlement and metamorphosis. In most species it unclear if, when under which conditions newly settled polyps are able capture ingest prey. This remains a critical knowledge gap, as coul...

The continental margin harbors a variety of habitats that support incredible biodiversity and the function their oceans' ecosystems. meiofauna is considered significant component benthic faunal community from polar to tropical regions. meiofaunal in deep Indian Ocean, especially along depth gradient, poorly investigated. present study aims explore structure gradients its associated environment ...

  Six different diets including two rainbow trout starters, Gammarus dry powder, shrimp dry powder, egg yolk dry powder and newly hatched Artemia were used in feeding of Caspian Kutum larvae. During a 4-week trial, larvae with a mean weight of 17.5 ± 4.7 mg were fed with three replicates and growth parameters were measured at the end of the experiment. Thirty fish in each experimental unit with...

 Co-feeding of fish larvae with live food and formulated diet has been at the focus of fish nutritionists since last decade. In this study we tried to refine the feeding practices of great beluga sturgeon (Huso huso) larvae using different combinations of newly hatched Artemia urmiana nauplii and trout starter diet. Three replicate groups (250 fish/replicate) of first-feeding Huso huso ...

A well known anti-cancer lignan arctiin has not been studied for its antibacterial activity based on our literature search. In the present work, the antibacterial and general toxicity of the arctiin from the seeds of Centaurea sclerolepis is studied. Arctiin did not show any significant antibacterial activity against both Gram-positive and Gram-negative bacteria when compared with the positive ...
