Band transformation secrets of Anemonefish <i>Amphiprion ocellaris</i>

902-904Present study consists the larval development of Amphiprion ocellaris and also documentation has done on the appearance of pigmentation and band formation, started appearing after post larval stage. Most interesting facts was recorded that on completion of 14-16th days, almost all the larvae attained full colouration of an adult fish and from day 25th onwards, all the coloured fins have got their peculiar parental traits and the total metamorphosis took place during this time. The miss band formation, band extension and band overlapping also observed in the anemone fish

Determining the level of parental care relating fanning behavior of five species of clownfishes in captivity

430-441Clownfishes <i style="mso-bidi-font-style: normal">Amphiprion sebae, A. clarkii, A. percula, A. ocellaris and Premnas biaculeatus were reared in captive condition and their parental care activities were studied.  Role of both male and female in parental care and terminating in successful hatching of eggs studied is described. Site selection, clutch formation, spawning, guarding, mouthing and fanning of the eggs were quantified. <i style="mso-bidi-font-style: normal">A. sebae exhibits more effective parental care for longer durations. The time spent on fanning was longer in <i style="mso-bidi-font-style: normal">A. sebae and shorter in A. clarkii.  Fanning frequency was higher in A. percula but lower in A. clarkii. In the five species the fanning duration and frequency were positively correlated to hatching success. Gradation of dissolved oxygen levels adjacent to the clutch area due to the fanning behavior is discussed.  Relation between body weight and the fecundity, fanning duration and frequency with hatching success are documented

Not AvailableA survey was conducted during the period of April-2014–April-2016 to note the occurrence of crabs in the beach area of Digha (21°37′48.092″N 87°32′41.355″E to 21°36′9.896″N 87°27′44.098″E) at the Bay of Bengal coastal zone, India. A total of 55 species of crabs belonging to 24 genera and 13 families have been recorded during the study period. From the data it is evident that the crabs belonging to the family Ocypodidae are dominant group (28%).Not Availabl
