A study just published in the Journal of Marine Biology sheds new light on the relatively rare but occasionally recorded presence of white sharks in waters surrounding the Hawaiian Islands, and suggests a new method to help distinguish between white sharks and close relatives, such as mako sharks. The paper, titled "Occurrence of White Sharks in Hawaiian Waters," was written by Kevin Weng of the University of Hawai'i at Mānoa's School of Ocean and Earth Science and Technology (SOEST) and Randy Honebrink of the Hawai'i DLNR Division of Aquatic Resources (DAR).
An exhausting battle spanning nearly 20 years for a new marine reserve in Akaroa Harbour is nearly at an end.
The Akaroa Marine Protection Society, a group of about 20 determined locals headed by husband and wife team Brian and Kathleen Reid, has been fighting for a 530-hectare marine reserve in Akaroa Harbour since 1996.
The reserve, near Dan Rogers Bluff, would protect about 12 per cent of the harbour from fishing.
This afternoon, Conservation Minister Nick Smith announced his approval of the reserve.
As part of the last meeting of the Convention on International Trade of Endangered Species of Wild Fauna and Flora (CITES), held this week in Bangkok (Thailand), the national government banned fishing for oceanic whitetip shark (Carcharhinus longimanus) in Brazilian waters.
The decision was made in order to preserve this endangered species.
According to a Normative Instruction of the Ministry of the Environment published in the Official Journal of Unión, the ban on fishing this resource MORE
Citizen science surveys compare well with traditional scientific methods when it comes to monitoring species biodiversity -- according to new research from the University of East Anglia.
Research published today in the journal Methods in Ecology and Evolution shows that methods to record marine diversity used by amateurs returned results consistent with techniques favoured by peer-reviewed science.
Conservationists look to final plenary to cement positive yet tentative decisions
Bangkok, 11 March 2013. In a highly anticipated Committee vote today, proposals to list under CITES* five species of sharks were supported by more than the two-thirds majority of voting countries needed for adoption. Conservationists are pleased yet mindful that decisions must still be confirmed in the final plenary session later this week.
Overfishing threatens the magnificent and prized ‘Ali Maduwa’, writes Malaka Rodrigo.
A giant “maduwa”, or manta ray, was netted last week by fisherman in Welipatanwila, Ambalanthota, on the South coast. The ocean creature was pregnant and weighed 1,500 kilograms. A week earlier, another manta ray was caught by fishermen in Akkaraipattu, on the East coast. Both sea creatures have been identified as Giant Oceanic Manta Rays, the largest member of the ray family.
