Three acetylenic brominated derivatives were isolated from a Red Sea sponge, Haliclona sp. One of them, 18-bromooctadeca-9(E),17(E)-dien-7,15-diynoic acid (3), is a known metabolite, and the other two are new compounds, (1E,5E,12E,19E)-1,22-dibromodocosa-1,5,12,19-tetraen-3,14,21-triyne (1) and methyl 18-bromooctadeca-9(E),17(E)-dien-7,15-diynoate (2) which was isolated for the first time as a ...

This study was performed to compare the efficiency of six microalgae namely Dunaliella tertiolecta, Tetraselmis suecica, Nannochloropsis oculata, Chaetoceros sp., Chlorella sp. and Spirolina sp. on the growth, survival rate and reproduction efficacy in Artemia urmiana in laboratory conditions. Artemia cysts were harvested from Urmia Lake and hatched according to the standard method. Live microa...

While copepods are important prey for many wild marine fish larvae and preferred as a live feed culturing larval fish, their low productivity the costs associated with them typically limit use food source in all but experimental situations. In series of experiments four readily commercially available microalgae (Thalassiosira weissflogii Grunow, Rhodomonas salina Wislouch, Tetraselmis suecica K...

Abstract The Mediterranean Sea is a hotspot for shark and ray extinctions home to the following three angelshark species: sawback Squatina aculeata , smoothback oculata common squatina . We conducted questionnaire-based survey in four coastal regions of Albania, Shëngjin (Lezhë), Vlorë, Himarë (Sarandë) Durrës, with aim collecting historical current data on catches Albanian seas (Adriatic Ionia...

Viruses are among the most abundant biological entities in ocean, largely responsible of modulating nutrients fluxes and influencing microbial composition functioning. In marine invertebrate holobionts like sponges their associated microbiomes, little is known about virome composition. Here, we characterized Haliclona fulva hologenome, an encrusting low-microbial abundance sponge found across W...

The scalpellomorph barnacle, Aurivillialepas calycula (Aurivillius, 1898), previously known only from Macaronesia, is reported from Banco de Galicia, off the NW corner of the Iberian Peninsula. One of the two specimens was attached to the scleractinian coral, Madrepora oculata Linnaeus, 1758. Since such pedunculate barnacles are little known, the potentially hermaphroditic specimens and its com...
