In this review, shark-fin-to-body-mass ratios, which have been legislated by several countries as a means of regulating and monitoring shark fisheries, have been compiled and reviewed. Observed and legislated wet-fin-mass-to-round-mass (M(fw) :M(r) ) ratios have been collected for 50 species and eight countries. Wet to dry-fin mass conversion factors have also been reviewed. Existing shark fishery legislation was compiled by political entity and regional fishery management organizations (RFMO…

ariation in whole-, landed-and trimmed-carcass and finweight atios for various sharks captured on demersal set-lines off eastern ustralia

Sharks are important apex predators in marine systems but many populations have experienced large declines, which has resulted in adverse effects on marine food webs. Sharks are also economically

Shark Conservation – Analysis and Synthesis

A detailed analysis of fishing records has shown that the shark species accessible to global fisheries have been systematically depleted for decades. They were already fished to about 10 percent of

Why have global shark and ray landings declined: improved management or overfishing?

Global chondrichthyan (shark, ray, skate and chimaera) landings, reported to the United Nations Food and Agriculture Organization (FAO), peaked in 2003 and in the decade since have declined by almost

Environmental, operational, and physiological causes of elasmobranch mortality during fisheries capture

Estimated declines in shark and ray populations worldwide have raised major, widespread concern about the impacts of global fisheries on elasmobranchs. The mechanisms causing elasmobranch mortality

The current status of elasmobranchs: biology, fisheries and conservation.

This Special Issue of the Journal of Fish Biology brings together a comprehensive series of review papers covering a wide field and a range of regular, original, scientific papers to highlight the current research being undertaken on this group of fishes.

Blood in the water: DNA barcoding of traded shark fins in Singapore

Overfishing has significantly decreased global shark populations, with some species experiencing reductions of approximately 70% over the last 50 years. Singapore is a major shark fin transhipment

Respiratory mode and gear type are important determinants of elasmobranch immediate and post-release mortality

This global meta-analysis provides the first quantified demonstration of how mortality is affected by respiratory mode and fishing gear type across a broad range of species, and can be applied to data-deficient elasmobranchs and fisheries to identify species that are likely to experience high rates of mortality due to respiratory mode or fishing methods used.

RATIOS BETWEEN THE WET FIN WEIGHT AND BODY WEIGHTS OF BLUE SHARK (Prionace glauca) IN THE SPANISH SURFACE LONGLINE FLEET DURING THE PERIOD 1993-2006.

The results confirm that these ratios, species combined, are mostly dominated by the ratio of the two most prevalent species, blue and short fin mako sharks, with a minor effect on the overall mean of the ratios of other less prevalent species.

PRELIMINARY REASSESSMENT OF THE VALIDITY OF THE 5% FIN TO CARCASS WEIGHT RATIO FOR SHARKS

The available data suggest that the aggregated 5% ratio is not inappropriate when using the primary fin set in the calculations, and the only guaranteed method to avoid shark finning is to land sharks with all fins attached.

PRELIMINARY RELATIONSHIPS BETWEEN THE WET FIN WEIGHT AND THE BODY WEIGHT OF SOME LARGE PELAGIC SHARKS CAUGHT BY THE SPANISH SURFACE LONGLINE FLEET

Preliminary results based on raw data obtained on board Spanish surface longliners regarding the relationships between the body weight of some most prevalent large pelagic shark species and their wet fin weight highlight the need to establish ratios for each species and fleet because the different criteria for dressing the fish, and the different fins or parts of fins used.

NEW DATA ON THE RATIO BETWEEN FIN AND BODY WEIGHTS FOR SHARK SPECIES CAUGHT BY THE PORTUGUESE SURFACE LONGLINE FLEET

New data is reported on the conversion rates for four pelagic shark species caught in the equatorial area of the Atlantic Ocean (between 5oN and 5oS) by the Portuguese longliners targeting swordfish.

Utilization of Deep-sea Sharks at Hatton Bank in the North Atlantic

During the last decade there have been an increasing commercial fishery in the Hatton bank area. On the west side of Hatton bank the catches consist of a large portion of deep-sea sharks. Utilization

FACTORS FOR CONVERSION OF FIN WEIGHT INTO ROUND WEIGHT FOR THE BLUE SHARK (PRIONACE GLAUCA)

Factors for the conversion of fins weight into round weight for the blue shark caught in the central-eastern Atlantic Ocean (Azores EEZ) by the Portuguese long-liners targeting swordfish are reported.

Global estimates of shark catches using trade records from commercial markets.

The results provide the first fishery-independent estimate of the scale of shark catches worldwide and indicate that shark biomass in the fin trade is three to four times higher than shark catch figures reported in the only global data base.

Sharks never stop growing and neither does the Asian demand for sharkfin soup. Ecuador is one nation of many that feeds the demand for fins, and fishers there catch more than 40 different shark
