Food Poisoning from Marine Toxins

By Vernon E. Ansdell Seafood poisoning from marine toxins is an underrecognized hazard for travelers, particularly in the tropics and subtropics. Furthermore, the risk is increasing because of factors such as climate change, coral reef damage, and spread of toxic algal blooms. CIGUATERA FISH POISONING Ciguatera fish poisoning occurs after eating reef fish contaminated with toxins such as ciguatoxin or maitotoxin. These potent toxins originate from small marine organisms (dinoflagellates) that grow on and around coral reefs. Dinoflagellates are ingested by herbivorous fish. The toxins are then concentrated as they pass up the food chain to large carnivorous fish (usually >6 lb, 2.7 kg) and finally to humans. Toxins are concentrated in fish liver, intestinals, roe, and head. Gambierdiscus toxicus, which produces ciguatoxin, may proliferate on dead coral reefs more quickly than other dinoflagellates. … Read entire article »

Hammerhead now under U.S. Federal protection under the Endangered Species Act.

    The federal government today listed four key populations of scalloped hammerhead sharks under the Endangered Species Act. The National Oceanic and Atmospheric Administration, for the first time in history, gave a shark species federal protections under the Endangered Species Act. The scalloped hammerhead shark is considered globally endangered by the International Union for the Conservation of Nature (IUCN). The species is targeted primarily for its fins but is also killed as “by-catch” in fisheries targeting other species. NOAA Fisheries listed scalloped hammerhead sharks inhabiting the Eastern Atlantic Ocean and Eastern Pacific Ocean as “endangered.” The agency listed scalloped hammerhead sharks living in the Central and Southwest Atlantic and Indo-West Pacific as the less-serious status of “threatened.” The federal agency declined to list scalloped hammerhead sharks that inhabit the Northwest Atlantic or Central Pacific. “This … Read entire article »

Expansion of US marine protected zone could double world reserves

  By Matt McGrath Environment correspondent, BBC News The US plans to create the world’s biggest marine protected area (MPA) in the middle of the Pacific Ocean. The White House will extend an existing protected area, known as the Pacific Remote Islands Marine National Monument. Fishing and drilling would be banned from an area that could eventually cover two million sq km. The extended zone would double the world’s fully protected marine reserves. Rare species The Pacific Remote Islands Area is controlled by the US and consists of seven scattered islands, atolls and reefs that lie between Hawaii and American Samoa. Essentially uninhabited, the waters that surround these remote islands are home to a wide range of species including corals, seabirds, sharks and vegetation not found anywhere else in the world. In 2009, President Bush declared … Read entire article »

The Deepwater Horizon Oil Spill and its Aftermath

Prologue to The The Deepwater Horizon Spill 20 April 2010 began as a day of celebration for The Deepwater Horizon, a 9-year-old offshore semi-submersible drilling rig engaged in drilling a deep exploratory well 18,360 feet (5,600 m) below sea level, in approximately 5,000 feet (1,500 m) of water in the Gulf of Mexico. Located in the Macondo oil prospect in the Mississippi Canyon, a valley in the continental shelf, it was one of the 3,858 oil and gas platforms that dotted the coastline of the five States of the USA bordering the Gulf as on 20 April, 2010 (Figs. 1 & 2). Built by Hyundai Heavy Industries of South Korea, and owned and operated by the Swiss-based offshore-oil-drilling company Transocean, the rig was leased by oil company BP (ex British Petroleum) … Read entire article »

Is it possible? 103 Y/O Orca… Sorry Seaworld.. Your professiona opinion is not accurate

  SeaWorld could be in trouble because of “Granny,” the world’s oldest known living orca. The 103-year-old whale (also known as J2) was recently spotted off Canada’s western coast with her pod — her children, grandchildren and great-grandchildren. But while the Granny sighting is thrilling for us, it’s problematic for SeaWorld. First of all, SeaWorld has claimed that “no one knows for sure how long killer whales live,” when simple figures or even living and thriving examples — like Granny — can give us a pretty good idea. The Whale and Dolphin Conservation project estimates that whales born in captivity only live to 4.5 years old, on average; many of SeaWorld’s orcas die before they reach their 20s. Perhaps because of their reduced lifespans, the whales are forced to breed continuously and at perilously young … Read entire article »

Slow life – A must watch

Daniel Stoupin is a PhD student in the University of Queensland. His research is in the field marine biology. Mixing his passions of biology and photography, Daniel has produce stunning photos and videos. “My interest in photography, especially in photomicrography, came from the scientific background. Working with microscopic protists during my first research years and later swimming countless nights with glowing plankton in the ocean opened my eyes on the diversity and complexity of life that we can’t see without tools. Although I am obsessed with marine life, particularly microscopic one and whatever glows in the dark, my photography interests are growing and eventually this website will change its name and become a lot more diverse in content.” – Daniel Stoupin   More pictures from Daniel    ““Slow” marine animals show their secret life under high … Read entire article »

Florida Fish and Wildlife Conservation Commission, FWC

  April, 2014 Commission Meeting Time: 8:30am each day Dates: April 15 – 17, 2014 Place: Florida Public Safety Institute 85 Academy Drive Havana, FL 32333 https://www.tcc.fl.edu/Current/Academics/FPSI/Pages/Directions.aspx This meeting is open to the public   8:30 a.m., Wednesday, April 16, there will be a presentation on the subject of LIonfsh Lionfish – Lionfish are invasive marine species that pose a threat to native  marine species and ecosystems.  Three draft rules will be proposed to prevent further lionfish introductions and facilitate efforts to remove these non-native predators.  Harvest by divers using either spearing gear or hand held nets is currently the primary means of lionfish population control. Persons diving by means of a rebreather are currently prohibited from harvesting any marine species in state waters.  A proposed draft rule would create an exception to allow persons using rebreathers to harvest lionfish.  In addition, there are several … Read entire article »
