Hypersensitivity to bloodworms (chironomid larvae) leading to asthma and other related allergic disorders is becoming common in individuals who keep or work with fish due to the increased use of bloodworms as fish food or bait.

Nematodes of the genera Anisakis and Pseudoterranova (family Anisakidae) are zoonotic parasites for which marine mammals (e.g., whales, dolphins, porpoises, seals, sea lions, walruses) act as final hosts, and crustaceans, cephalopods and fish as intermediate and/or paratenic hosts. In humans, the ingestion of Anisakidae larvae can result in infection with live larvae, an allergic reaction to An...

Colonization of the lagoon at Moorea Island, French Polynesia, by fish larvae was studied with a net fixed on the outer reef crest in order to observe die1 and lunar cycles. Fish larvae entered the lagoon at dusk and at night, mainly during moonless periods. Colonization was closely related to decreasing light intensity; it was 4 times greater during new moon than during full moon. Other enviro...

The Lower Miocene deposits in Gabal Gharra, Cairo – Suez District, unconformably overlies the Oligocene and Eocene deposits. They consist predominantly of regressive and transgressive mixed siliciclastic / carbonate sediments of shallow marine environments. The Lower Miocene deposits are represented lithostratigraphically by the Gharra Formation that comprises four members, from base to top: Ag...

Due to the negative consequences associated with the use of antibiotics, researchers, and food producers have studied alternatives, such as probiotics, for the control of fish diseases. The probiotic properties of yeasts in aquaculture have been scarcely considered. The present study investigated the probiotic properties of local yeast strains for aquaculture application in the protection of ba...

The larvae of grass carp Ctenophargodon idella were fed on three types live food Brachionus calyciflorus, Artemia sp. and Daphnia magna. study showed that is very important to achieve high growth survival fish larvae. average weights C. B. calyciflorus 118.12+3.0 mg / 29.48+0.8 mm respectively, in case rates 103.13+1.5 mg/ 25.34+1.4 larvae, while the mixed rate 122.80 + 1.8 30.08 1.1mm /larvae ...

Coralline algae are globally distributed benthic primary producers that secrete calcium carbonate skeletons. In the context of ocean acidification, they have received much recent attention due to the potential vulnerability of their high-Mg calcite skeletons and their many important ecological roles. Herein, we summarize what is known about coralline algal ecology and physiology, providing cont...

To analyze the potential trophic interactions among tuna larvae and other fish species, we studied the larval fish assemblages inhabiting the surface mixed layer around the Balearic Islands using data from two surveys carried out in summer 2006 and 2008. Despite the high diversity, Thunnus alalunga, Auxis rochei, Cyclothone pygmaea and Ceratoscopelus maderensis clearly dominated the catch in bo...

Many coral reef fish larvae spend days to months in the open ocean before settlement on coral reefs [1]. Early in development, larvae have limited swimming capabilities and will therefore be greatly affected by currents. This can potentially result in dispersal distances of tens of kilometers [2]. Nevertheless, up to 60 % of surviving larvae have been shown to return to their natal reefs [2]. T...
