Buddhists fined almost £30,000 – for releasing foreign lobsters bought in Greenwich into the sea.

Ni Li and Zhixiong Li were among 100 Buddhists who released the crustaceans into the Channel as part of a religious ceremony – despite them being an invasive species. They spent more than £5,500 on 361 live American lobsters and 35 Dungeness crabs, which they released from three boats, chartered off Brighton Marina.,,, But the ceremony on June 15, 2015 wreaked havoc on local marine life, forcing the Marine Management Organisation (MMO) to offer local fishermen £20 for each alien lobster they caught. click here to read the story 11:48

Kentucky State Fish and Wildlife Department seeking input on entrepreneurial solutions for Asian carp problem

Asian carp swim by the millions in Kentucky’s waterways, threatening to crowd out native fish in some of the state’s most cherished fishing destinations – including Kentucky and Barkley lakes in the west. With an absence of predators and little natural controls available for these invasive species, the Kentucky Department of Fish and Wildlife Resources, the state Tourism, Arts and Heritage Cabinet and the Commonwealth of Kentucky are seeking public input on a plan to limit the explosive growth of Asian carp populations while providing a valuable protein source for people. State officials will evaluate a potential public/private partnership to boost the emerging Asian carp fish processing business in Kentucky. State support of entrepreneurs could include hiring commercial anglers and rental of necessary equipment; supplying freezer space in warehouses; purchasing catches during low demand times; and cash incentives, among other potential solutions. click here to read the story 08:30

Telling it like it is! NOAA has done enough already and has failed in spectacular fashion

One wonders why a Marine Sanctuary is needed to protect shipwrecks.  Sanctuaries are usually established to protect ecosystems.  The typical reason for establishing a Sanctuary off our shores is inapplicable because our native ecosystem has been destroyed. After the opening of the Saint Lawrence Seaway in 1959 NOAA was assigned the responsibility of protecting the Great Lakes from invasive species, essentially making the entire region a sanctuary.  NOAA has failed in spectacular fashion.,, NOAA allowed the Lamprey Eel and Alewife into our native waters shortly after the Seaway opened. These and other foreigners decimated our native fishery.  Smelt survived until the 1980’s but now they too have been displaced by some other invasive species that NOAA failed to protect us from, was it the Quagga Mussel or the Round Gobi?

REWARD!! Michigan DNR Offers Big Reward For Plan To Block Invasive Fish

If the fishing world had a most-wanted list, Asian carp surely top it. There are plenty of despised invasives plaguing U.S. waters, but how many of them have a $1 million dollar bounty on their heads? That’s what the Michigan Department of Natural Resources just dropped on the table. Show the agency a viable plan for stopping those silver and big head carp from reaching the Great Lakes and you could be eligible for a sweet payday. In case you haven’t already heard the tale, Asian carp are prolific breeders that can reach 50-pounds. The filter-feeding invasives consume massive amounts of the tiny plants (phytoplankton) and animals (zooplankton) that feed native forage species, along with juvenile sport fish such as walleye and yellow perch. Disrupting the food web can wreak havoc on local fisheries. Read the story here with link to DNR 12:21

Invader green crabs from Europe threaten havoc in Puget Sound

20160914_gd_green_crab-550x440Emily Grason and Sean McDonald trudge through the mud of San Juan Island’s Westcott Bay on the hunt for something they hope not to find: A 3-inch menace: the European green crab. In late August, a single adult male was found for the first time in Washington’s inland sea. University of Washington researchers responded, arriving at the location of that first sighting  with hundreds of traps in tow. “It might seem like it’s crazy for us to have such an intense trapping effort for just a single crab being found. One crab, what’s the big deal?” says Emily Grason, project coordinator for the Washington Sea Grant Crab Team. “But these crabs do tend to show up in numbers and where there’s one, there’s often more.” Video, read the story here 17:24

EU approves Sweden’s American lobster assessment

lobsterDM0811_468x521The Swedish risk assessment of American lobster is now approved by the EU, furthering the process that could lead to American lobster being added to the list of invasive species. ‘It is of course positive that our risk assessment meets the requirements of the EU regulation,’ said Sofia Brockmark of the Swedish Agency for Maritime and Water Management (HaV). The regulation aims to prevent, minimise and mitigate the impacts of invasive alien species of animals and nature, human health or the economy. It requires Member States, inter alia, to identify how the species spread and to ensure that the spread is stopped or limited. The species on the list are also subject to various restrictions, including the ban on the import, breeding or keeping alive. Now that the risk assessment has been approved by the EU’s scientific forum for invasive alien species, it can be put forward to the EU’s executive committee. Read the story here 09:03

EU moves one step closer to banning North American lobsters

American-lobsterThe European Union has moved one step closer to a possible ban on live North American lobsters after its scientific advisory forum released a recommendation in favour of including the animal on its invasive species list. In a decision released Tuesday morning, the EU scientific forum said it has submitted a “positive opinion” on the validity of an earlier proposal from Sweden to ban lobsters from Canada and the United States. A final decision by the EU is expected in April of 2017. In December, 2015, Sweden proposed a ban on live North American lobsters in the EU. In its proposal, Sweden argued that North American lobsters have been found in European waters in the past, and that the species could threaten local species. Read the rest of the story here 10:23

Why Green Crabs Are Invading the East Coast

green-crabsIn the Gulf of Maine, as elsewhere in the world, many species are feeling the pressure brought on by climate change. A changing environment makes them more susceptible to one existential threat: invasive species. This, in turn, is having a huge impact on the local fishing industry that employs tens of thousands of people in the area, and provides seafood to the local restaurants that Maine is famous for. In short, the health of the Maine economy largely depends on the health of the Gulf of Maine, and the marine species that have made it their home. But invasive species like green crabs are coming in and wreaking havoc. Foreign species are defined as invasive when they cause the displacement of an endemic one. In the Gulf of Maine, that includes eelgrass, blue mussels, oysters, and many other types of shellfish. Invaders disrupt the trophic hierarchy,, Read the story here 15:35

The seemingly ‘unstoppable’ lionfish flooding Florida’s coast and beyond

1469726857_lionfish1995-2015In 2011, when Rachel Bowman saw an abundance of large, pretty reddish fish while riding in a boat across the Florida coast, she didn’t think much of it. But a year later, once she got certified to dive, she speared the exotic fish and recognized an opportunity. Three years later, the fisherwoman, who was born in North Carolina and whose father was a shrimper, is selling this creature, called lionfish, to restaurants, local markets and 26 Whole Foods Markets across Florida. “I’m the first person to sell [lionfish] to Whole Foods and to set up that deal,” Bowman told CNBC. And in the Sunshine State, many other commercial fishing operations have begun to sell lionfish as well. The fish’s reproductive habits may bolster their successful invasion. Females may be able to spawn as often as every four days, which could result in the release of up to 2 million eggs a year from a single fish, according to USGS. Read the story here 08:05

What a surprise! Fishermen can catch grass carp, but government scientists can’t!

Despite Quebec’s investment of $1.7 million to tackle a possible grass carp invasion, scientists have yet to locate any specimens themselves. Quebec’s Forests, Wildlife and Parks Ministry was quick to roll out a plan to combat the invasive species after two fishermen in the Lanaudière region caught a 29-kilogram grass carp in the St. Lawrence River May 27. Government scientists’ subsequent fishing expeditions have taken place in the Contrecœur area, about 60 kilometres northeast of Montreal. Tuesday, the ministry announced they have come up empty-handed. At this stage, laboratory tests are underway to determine the presence of grass carp DNA in the St. Lawrence River, sampling water from different areas. Those results will be available at the beginning of July. The grass carp is a type of Asian carp. The one that was caught in the St. Lawrence River was estimated to be between 15 and 30 years old. link 10:17

Maine lobster suppliers joined Massachusetts and Canadian peers in Brussels to foil EU import ban

10-lobsters1The six Maine companies joined their Massachusetts and Canadian peers, as well as national trade officials, to discuss the proposed ban with buyers and trade officials from eight European countries, including the three biggest importers of Homarus americanus: France, Italy and Spain. The meeting occurred at the world’s largest seafood industry trade show, said spokesman Gavin Gibbons of the National Fisheries Institute, an American seafood industry trade group. About 75 people met for 90 minutes to talk about how to avoid the all-out ban that Sweden asked the European Union to adopt in March after finding North American lobsters in European waters.

Fishermen encouraged to take big bite out of Bay’s blue catfish population

For years, Rocky Rice made his living primarily by fishing two of the Bay’s most iconic species: striped bass in the spring and blue crabs much of the summer. But after several years of poor blue crab catches, and with new catch limits on striped bass being put in place, Rice added one of the Bay’s most troublesome species to his mix: blue catfish. Rice is one of a growing number of fishermen responding to the plea of fishery officials to catch as many of the voracious predators as they can. Read the rest here 17:07

Invasive Impact: What’s the Status of Invasive Species in Alaska?

Fisheries are an economic and employment engine in Alaska, with the commercial and recreational sectors generating $4.8 billion in sales impacts and 61,000 jobs in 2012. However, invasive species, or species that are introduced to a new area where they have the potential to cause harm, could significantly affect the ecosystems that make Alaska so productive for fisheries.  Read the rest here 08:24

DFO find’s non native shrimp along the shores of Newfoundland’s west coast.

For the second time this year, DFO scientists have discovered a new species in the province’s coastal waters. Baltic shrimp have now found a permanent home in Newfoundland. Specimens have been identified from the Magdalen Islands to York Harbour. “Despite regulation, ballast water controls and for transportation and that kind of stuff coming from other countries, things are slipping through the cracks,” he said. In December, DFO scientists discovered a new species of razor clam based on samples collected,,, Read the rest here  07:33

Lionfish Causing Problems for the Panhandle

The FWC has been bringing awareness to some of Florida’s most invasive species with Invasive Species Awareness Week. One particular highlighted menace has been creeping into the Gulf since 1985. The lionfish is causing problems for some of Florida’s native species which is in turn causing problems for both recreational and commercial fishing, especially here in the Panhandle.

One Great Lakes invasive species may have found a niche

Can invasive species be good news – rather than bad – for native fish in the Great Lakes?  That sounds counterintuitive, but a new study shows that the invasive round goby has become an important food source for several native species, especially smallmouth bass, but with benefits also for yellow perch and walleye. The study calls the round goby “one of the most successful aquatic invaders” in the Great Lakes. Read the rest here 18:03

Lake Manitoba Commercial Fishing In Jeopardy

The local commercial fishing industry is being threatened by the people_perry_gaudry into Lake Manitoba. Fishermen have noticed more jackfish, also known as northern pike, since water from the Assiniboine River was diverted into Lake Manitoba during the flood of 2011. Perry Gaudry’s a commercial ice fisherman, and says the increased population is starting to reduce the population of the other fish. Read the rest here 12:27

No profits found in this tangled catch – Fishermen taking a beating!

Heterosiphonia japonica RILocal fishermen this year have had a tough time with a species of red seaweed, an algae, that looks like matted hair. The algae began to bloom and spread in May. Nets would get fouled – often beyond recognition – and the fishermen would spend hours cleaning them, only to have their nets get “weeded up” on the very next tide. And to add insult to injury, when the weed was thickest, covering acres of the seabed, the nets would often be empty of fish. Read the rest here 13:23

Green Crab found near Pool’s Cove – Could be a serious issue in Fortune Bay

According to Cynthia McKenzie, a research scientist with Fisheries and Oceans, the green crab has established a foothold in the Pool’s Cove area of Fortune Bay. She said DFO issued experimental licenses to the Conne River Band and a group in Pool’s Cove this past summer to catch green crab. Read the rest here 09:59

Lime does not harm lobsters or other marine life, study shows

Tunicate are an invasive species that are a serious threat to the mussel industry. Tunicate attach themselves to mussel socks, completely covering them and making it difficult for the mussels to feed. Lime is used in the mussel industry to remove tunicate from the lines. Lime is also used in the oyster fishery, mainly to remove starfish. Read the rest here 08:04

Portland Press: Our View: Public-private partnership critical to kicking green crab out of Maine

Given how high the stakes are for the state’s marine habitat and its third-largest commercial fishery, Maine has to focus on removing green crabs from coastal waters as quickly as possible. As state marine ecology researcher Brian Beal told the Press Herald in February: “How do you get rid of an invasive species? You fish ‘em to death. We did an awful good job of reducing the population of sea urchins without even trying.” Read more here 10:17

Can US eliminate invasive species by eating them?

HOUSTON (AP) – It seems like a simple proposition: American lakes, rivers and offshore waters are filling up with destructive fish and crustaceans originally from other parts of the world, many of them potential sources of food. So why not control these invasive populations by getting people to eat them? Read more here 13:16

Snakeheads break out of Potomac, enter Rappahannock River

Richmond Times-Dispatch – The northern snakehead, an invasive species of fish native to Asia, has successfully broken out of the Potomac River system and established itself in the Rappahannock River, according to state officials. The fish drew headlines when it turned up in a Maryland pond in 2002, in part because of its prodigious teeth and ability to survive several days out of water by breathing air. Spotted less than a decade ago in the Potomac, the snakehead has not just survived, but spread. continued

State senator’s bill aims to reel in ‘rotten invasive’ sea lamprey

A bill circulated by a Republican lawmaker aims to control sea lamprey — eel-like parasites that look like monsters, attack trout and other fish, and could suck the lifeblood out of the Great Lakes ecosystem. The toothy invasive species threatens the commercial and recreational fisheries and tourism industry, said the bill’s sponsor, Sen. Robert Cowles, R-Green Bay. continue reading
