Ichthyology and Marine Biology

A diverse assemblage of large mammals is spatially and stratigraphically associated with Ardipithecus ramidus at Aramis. The most common species are tragelaphine antelope and colobine monkeys. Analyses of their postcranial remains situate them in a closed habitat. Assessment of dental mesowear, microwear, and stable i…

BACKGROUND: International fish trade reached an import value of 62.8 billion Euro in 2006, of which 44.6% are covered by the European Union. Species identification is a key problem throughout the life cycle of fishes: from eggs and larvae to adults in fisheries research and control, as well as processed fish products…

Left-right asymmetries are most likely a universal feature of bilaterian nervous systems and may serve to increase neural capacity by specializing equivalent structures on left and right sides for distinct roles. However, little is known about how asymmetries are encoded within vertebrate neural circuits and how later…

Weight-Length relationships (WLRs) were estimated for 39 fish species from the north-eastern Mediterranean coast of Turkey. Samples were collected using trawl and longline gears at depths ranging from 5 to 100 meters. Captures were made between the years 2001 and 2003. The best-represented family was Sparidae with sev…

BACKGROUND: Whale sharks are a declining species for which little biological data is available. While these animals are protected in many parts of their range, they are fished legally and illegally in some countries. Baseline biological and ecological data are needed to allow the formulation of an effective conservati…

Length–weight relationships were estimated for 11 elasmobranch and 51 teleost fish species caught in Izmir Bay, Turkey. Sampling was carried out from June 2005 to May 2006 at monthly intervals using a bottom trawl net. The mean b-value was calculated as 3.10 (SE = ±0.03) and only three species were out of range betwee…

To investigate the functional organization of higher brain levels in fish we test the hypothesis that the dorsal gray mantle of the telencephalon of a mormyrid fish has discrete receptive areas for several sensory modalities. Multiunit and compound field potentials evoked by auditory, visual, electrosensory, and water…

Weight–length relationships were estimated for 20 Lessepsian fish species of the Iskenderun Bay, namely, Apogon nigripinnis, Apogon queketti, Callionymus flamentosus, Cynoglossus sinusarabici, Dussumieria elopsoides, Etrumeus teres, Fistularia commersonii, Lagocephalus spadiceus, Lagocephalus suezensis, Leiognathus kl…

The Mediterranean Large Elasmobranchs Monitoring (MEDLEM) database contains over 3000 records (more than 4000 individuals) of large elasmobranch species from 20 different countries around the Mediterranean and Black seas, observed from 1666 to 2017. The main species included in the archive are the devil fish (1 813 in…

Length-weight relationships are presented for ten shark species sampled with a commercial trawl vessel at depths ranging from 5 to 500 m between March 2005 and June 2008 in Saros Bay, Turkey. The values of the exponent b of the length-weight relationships ranged from 2.6816 to 3.6060.
