Food partitioning between species is a common strategy for avoiding resource competition which allows the coexistence of two or more in same place. In order to evaluate feeding four batoids regularly caught by artisanal fisheries southern Brazil, present study aimed analyse and compare diet batoid species. The Chola guitarfish, Rhinobatos percellens , had specialized diet, consisting predominantly blue crabs Callinectes sp., followed teleost fish. Lesser guitarfish Zapteryx brevirostris also...
Bacterial diseases of marine fish inflict significant economic damage to fisheries and aquaculture pose an increasing risk public health. When addressing disease, accumulating body research suggests adding another factor the classic epidemiological triangle host-environment-pathogen: microbiome. The gills, being a gateway into bearing important role in homeostasis, have been found be proxy gut microbiota as well reflecting microbial communities surrounding water. In this study, 16S rRNA...
Abstract Marine wildlife stranding is a global phenomenon, and for some taxonomic groups, these events are well monitored documented. Although sharks among the most threatened vertebrates, strandings have historically been neglected, with little information on this topic currently available. To address knowledge gap, systematic review scientific publications from indexed databases, multimedia material citizen science databases was performed. A total of 3150 reports were recovered, dating...
Abstract Sharks and rays are among the most threatened vertebrates, mostly due to commercial fisheries. Data on incidental capture is sparse, but it estimated that about 50% of reported global catches elasmobranchs from bycatch. Elasmobranchs captured in a variety fishing gear throughout world. One promising strategy minimize release live sharks rays. However, so far, no critical analysis had been carried out assess importance as measure mitigate impacts Results indicated despite onboard...
Abstract The fate of bycatch species released back into the water is crucial to estimate population status and consequent decisions implement adequate management measurements for elasmobranchs. shortnose guitarfish, Zapteryx brevirostris , an endemic Southwest Atlantic. It currently listed as ‘Vulnerable’ both in International Union Conservation Nature Brazilian red lists. Although this displays high tolerance capture transportation by fishers from site fish market, a significant reduction...
Guitarfishes are of particular concern for marine conservationists, as their populations declining at alarming rates, and more than 70% these species is listed under some threat category or data deficient. Furthermore, 60% currently described species, risk assessments have not been reviewed over a decade (Moore, 2017). Another aggravating factor conservation that guitarfishes considered ‘charismatic’, posing an extra challenge to public commitment fundraising. Many threatened guitarfish...
International wildlife trade is a major source of biodiversity loss, yet many species lie hidden within aggregated data that conceals impacts. We overcome this problem for the largest vertebrate globally - shark and ray meat comprising 438 538 mt yr-1 across more than 150 species, 76% which are Threatened. Revealed contains greater quantities skates (+10%), hammerheads (+8%), smoothhounds, dogfishes & tope (+5%), fewer pelagic sharks (-38%) previously known. Shorttail yellownose skate,...
Anthropogenic activities are affecting marine ecosystems, notably coastal ones, in multiple ways and at increasing rates, leading to habitat degradation, loss of biodiversity, greater exposure flora fauna chemical contaminants, with serious effects on ocean health. Chemical pollution, particular, is a significant negative stressor for aquatic both oceanic coastal, has recently been identified as priority conservation efforts. Metals metalloids, present environmental persistence,...
Introduction The current Isogomphodon oxyrhynchus (Daggernose Shark) population status Q7points to 99% losses in the last decade due certain biological traits, site fidelity, and historical high representativeness as bycatch artisanal fisheries. This species is listed Critically Endangered (CR), both IUCN Brazilian Red Lists. Its vulnerability so that its recovery potential requires protection from ongoing fishing pressure. Objective In this context, study aimed evaluate health of Daggernose...
Elasmobranchs are essentially marine, but ~15% of the species occur in brackish or freshwater. The Brazilian marine coastal skate Zapteryx brevirostris, non-reported nearby estuaries, was submitted to 35, 25, 15, and 5 psu, for 6 12h (n=6). Plasma assayed osmolality, urea, ions (Na(+), Cl(-), K(+), Mg(2+)). Muscle water content determined, rectal gland, kidney gills were removed carbonic anhydrase (CA) Na(+),K(+)-ATPase (NKA) activities. survived all treatments. osmolality urea levels...
Streptococcosis is an infectious bacterial disease of both homeotherms and poikilotherms. Among the Streptococcus species that infect marine animals, agalactiae has broadest host spectrum, including different aquatic organisms in freshwater environments. The common dolphin ( Delphinus delphis ) categorized as Endangered Mediterranean Sea. There are few reports a streptococcal infection D . , caused by phocae iniae Here we report isolation identification S stranded, wild male was found dead...
