Female lemon sharks born in Bimini returned to give birth on the same island 15 years later, confirming natal philopatry. Local and international conservation efforts can make a significant impact in recovering coastal shark populations.
A new study published in PLOS ONE found that winter flounder populations in Long Island's bays are experiencing severe inbreeding due to low effective numbers of breeders. This has significant implications for fisheries management and the long-term survival of these marine fish.
A study on oceanic whitetip sharks reveals they spend most of their time in Bahamian waters but roam long distances, highlighting the need for international conservation measures. The research provides key findings for protecting this species, which is listed as Critically Endangered globally.
Dr. Ellen K. Pikitch cautions against traditional fisheries management, citing current studies that show fish populations are below recommended levels and most species are declining. A more precautionary approach is needed to protect marine ecosystems.
A recent study led by the Institute for Ocean Conservation Science provides a first-time analysis of the value of forage fish to both commercial fisheries and marine ecosystems. The research found that forage fish contribute significantly to global fisheries, with a total estimated value of $16.9 billion annually, representing 20% of g...
A recent study by the Institute for Ocean Conservation Science found that international protection of sturgeon species has reduced fraudulent labeling of black caviar. The research revealed a nearly 50% decrease in mislabeled products, indicating the effectiveness of trade regulation.
A team of scientists from the Institute for Ocean Conservation Science used video cameras to count Caribbean reef sharks inside and outside marine reserves on the Mesoamerican Barrier Reef. The results show that the sharks were more abundant in the reserves, with a higher relative abundance compared to areas where fishing is allowed.
A study reconstructing 700 years of human-environment interactions in Hawaiian coral reefs found that historical changes in human societies led to degradation or recovery. While some reefs declined due to overexploitation and land-based pollution, others recovered through cultural protection and conservation efforts.
A study by the Institute for Ocean Conservation Science uses DNA testing to identify separate populations of dusky and copper sharks in different coastal regions, allowing for tracking of their origins and informing management of the shark fin trade. The research demonstrates that genetic differences among regional groups can be used t...
A recent study tracked Atlantic sturgeon migrations, revealing vast oceanic distances traveled and highlighting the need for long-range conservation measures. The research suggests that PSAT technology can effectively study sturgeon behavior and define critical habitat.
The IUCN has reclassified beluga sturgeon as 'critically endangered', with the Institute for Ocean Conservation Science applauding the move. This classification underscores the need for swift, international protection to help conserve this species from extinction.
A joint study by American and Kazakhstani scientists reveals that reducing adult mortality is key to recovering beluga sturgeon populations. The study suggests that limiting the take of adult and subadult sturgeon will contribute more to population growth than hatchery supplementation.
