Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Distribution of skates and sharks in the North Sea: 112 years of change [PDF]
How have North Sea skate and shark assemblages changed since the early 20th century when bottom trawling became widespread, whilst their environment became increasingly impacted by fishing, climate change, habitat degradation and other anthropogenic ...

Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.

Economic and labour market implications of climate change on the fisheries sector of the Maltese Islands [PDF]
Climate change has been predicted to have large and rapid impacts on the Mediterranean Sea. Impacts of increasing mean annual sea temperatures, more extreme climatic events and changes in oceanographic parameters will a ffect the distribution ...

Abstract Wnt proteins are a family of molecules that help control how cells grow, develop and communicate – processes that are fundamental to the development and health of all animals. Although Wnt pathways have been studied extensively in model species, very little is known about how they operate in marine fish.

Results from RV Utafiti research cruises [PDF]
Monthly fish surveys were made from 1997-1999 in the Kenyan waters of Lake Victoria in order to estimate the magnitude of fisheries resources. Sample sites were defined using GPS while thirty minute hauls in alternate grid squares were made.

Abstract This study reports three cases of pigmentation disorders in Squalus acanthias from the Gulf of Venice. Two specimens exhibited spotless phenotypes, whereas one exhibited hypermelanism. Morphological assessments were conducted for two individuals, alongside genetic analysis of mitochondrial genes to determine phylogeographic relationships. Both

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

Two genera of the poorly known family Cetomimidae (flabby whalefishes), Cetomimus Goode and Bean, 1895 and Gyrinomimus Parr, 1934, are morphologically similar but differ in jaw tooth row (indistinct diagonal rows in Cetomimus vs.

Demersal Fish Resources Around Qatar
The study was based on the data available from Fishery Resources Survey in the Gulf and Gulf of Oman, conducted by F.A.O., between 1975 and 1979 and the samplings of the fish production in Qatar during 1980/81. The survey was conducted with standard type Engel high opening trawl, having a 32mm mesh codend, and the sampling stations were randomly ...
