Analysis of Demersal Fish Fauna off the Sea of Marmara, Turkey

open access: yesÇanakkale Onsekiz Mart University Journal of Marine Sciences and Fisheries, 2021
Demersal fish fauna of the Sea of Marmara, Turkey was determined by bottom trawl surveys between March 2017-December 2018 at 34 stations with the monthly samplings. During the study, a total of 61 teleost and 12 cartilaginous fish species belonging to 42

Afferent connections of the valvula cerebelli in two teleosts, the common goldfish and the green sunfish [PDF]

open access: yes, 1989
The afferent connections of the valvula cerebelli were examined in one cypriniform teleost (Carassius auratus) and one perciform teleost (Lepomis cyanellus) with the use of horseradish peroxidase as a retrograde tracer.

Hypothesis and Theory: Evaluating the Co-Evolution of the Melanocortin-2 Receptor and the Accessory Protein MRAP1

open access: yesFrontiers in Endocrinology, 2021
The melanocortin receptors (MCRs) and the MRAP accessory proteins belong to distinct gene families that are unique to the chordates. During the radiation of the chordates, the melancortin-2 receptor paralog (MC2R) and the MRAP1 paralog (melanocortin-2 ...

Deep-Water Cartilaginous Fishes in the Central Mediterranean Sea: Comparison between Geographic Areas with Two Low Impact Tools for Sampling

open access: yesJournal of Marine Science and Engineering, 2021
Baited lander represents a low impact technique, an alternative to the traditional trawl sampling for collecting data on fish diversity and abundance, especially for threatened species such as Chondrichthyes living in sensitive habitats.

El sistema reproductor femenino de Zearaja chilensis (Guichenot, 1848) (Chondrichthyes, Rajidae): Gametogénesis y validación microscópica de los criterios de madurez [PDF]

open access: yes, 2015
Los condrictios son extremadamente susceptibles a la explotación pesquera debido, entre otras cosas, a sus adaptaciones reproductivas. Los conocimientos básicos de sus parámetros reproductivos son esenciales, ya sea desde el punto de vista ecológico como
