Effect of Temperature on Embryonic Development in Sharpsnout Seabream (diplodus Puntazzo) Eggs
نویسندگان
چکیده
Embryonic development of sharpsnout seabream (Diplodus puntazzo) was studied at eleven water temperatures (two degree intervals from 12 to 32°C). Embryos successfully developed at temperatures of 16-28°C. Cells did not divide at the temperature extremes of 12 and 32°C. Total mortality was observed by the 128 cleavage stage at 14°C and all eggs were dead by the time the embryos extended 2/3 of the internal circumference of the egg at 30°C. There was an inverse relationship between incubation temperature and the rate of embryonic development.

Comparative Ontogeny of the Digestive Tract in Sharpsnout Sea Bream Diplodus puntazzo Cetti and Common Pandora Pagellus erythrinus L
The ontogeny of the alimentary tract and its associated structures (liver, pancreas, gall bladder) was compared between sharpsnout sea bream Diplodus puntazzo and Pagellus erythrinus and some differences were highlighted. The first goblet cells appeared earlier in sharpsnout seabream (5-7 DAH) and later in common pandora (9-11 DAH), as well as taste buds which appeared at 11 DAH in sharpsnout s...

The structure of the developing thymus of the marine teleost, Diplodus puntazzo, was studied by light and transmission electron microscopy. The first anlage of the thymus developed by d 20 postfertilisation (p.f.) as a group of undifferentiated cells dorsal to the epithelium of the branchial chamber. The organ increased significantly in size around d 51-66 p.f. and differentiation of cortex and...

The ontogenetic development and pattern of main digestive enzyme activities (proteases, carbohydrases and lipases) were investigated in farmed sharpsnout seabream Diplodus puntazzo larvae and juveniles, during the passage from the larval stage to adult (from 21 to 277 days after hatching DAH). Larvae showed exponential growth, thus confirming that Rotifers and Artemia nauplii are suitable preys...

BACKGROUND Edwardsiella tarda, is a serious bacterial pathogen affecting a broad range of aquaculture fish species. The bacterium has also been reported as a human pathogen, however recent studies have dissociated the fish pathogenic Edwardsiella from those isolated from humans by placing them in a new species, E. piscicida. Here we report the first case of Edwardsiellosis in cultured sharpsnou...
متن کاملAroclor 1254 inhibits the chemiluminescence response of peritoneal cavity cells from sharpsnout sea bream (Diplodus puntazzo).
Chronic exposure to polychlorinated biphenyls (PCBs) affect the immune system of fish and could lead to a decreased disease resistance. The effects of Aroclor 1254, PCB mixtures, on the Diplodus puntazzo innate immunity were examined by assaying the zymosan stimulated chemiluminescence response (CL) of peritoneal cavity cells (PCCs) at various times (1, 24, 48 h and 1-4 weeks) from intraperiton...
