The present work deals with the study of the fish larvae of coral reef fishes in the Red Sea (Hurghada). It aimed to study the spatial and temporal variations of fish larvae for the management purposes. Sampling stations were Marina, Sheraton, Magawish and Arabia. The samples were taken monthly throughout the period of study from August 2014 to July 2015 using plankton net with different mesh s...
myiasis is the condition of infestation of the body by fl y larvae (maggots). the deposited eggs develop into larvae, which penetrate deep structures causing adjacent tissue destruction. it is an uncommon clinical condition, being more frequent in tropical countries and hot climate regions, and associated with poor hygiene, suppurative oral lesions, alcoholism and senility. the diagnosis of myi...
Paenibacillus larvae is the etiological agent of American foulbrood (AFB) disease, a contagious bacterial disease that infects honeybees (Apis mellifera L.). Screening naturally occurring compounds to negate concerns related wide use antibiotics an urgent need for prevention and treatment AFB disease. In this study, we demonstrated crude ethanolic extracts (CEEs) from leaves Trapa bispinosa Rox...
This study aimed to investigate the fatty acid composition of zooplankton and common carp larvae in hatcheries at the first seven days of larval rearing. SFA was higher in rotifers before releasing of larvae on = day 1 gain (6.15%), compared to that of day 7, and significantly decreased in the rate of 3.53%. On day 7, total amount of MUFA was increased significantly. Oleic acid was the most dom...
The larval community of coral reef fishes in the Red Sea was studied in coastal and offshore sites to determine the effects of the exposure to waves and currents and the distance from the shore in structuring the larval fish community. Plankton sampling from inshore and offshore sites and the exposed and sheltered sides of the reefs resulted in the collection of 2048 larvae representing 49 diff...
The effects of stocking density of eggs and larvae were studied related to the morphological deformities appearance, percentage of survival, and growth rate, in order to achieve the most suitable stocking density for eggs and larvae in incubators and rearing tanks. The egg stocking densities were 500, 700 and 900 g per incubator for great sturgeon, 500 and 1000g per incubator for Persian sturge...
feeding behavior of yellowfin seabream larvae during the first two weeks of larval life was studied by feeding larvae on different ratios of live food and microencapsulated diet (med). food consumption rate increased progressively with increasing larval weight. the results from visual observation of the larval guts under a light microscope indicated that yellowfin seabream larvae were able to...
