Information in support of a recovery potential assessment of Mountain Sucker (Catostomus platyrhynchus), Milk River populations (Designatable Unit 2 D.A. Boguski and D.A. Watkinson

Canadian Science Advisory Secretariat. Department of Fisheries & Oceans.

ABSTRACT

In Canada, the Milk River system populations of Mountain Sucker (

 

Catostomus platyrhynchus) are distributed in southwestern Saskatchewan and west in the Milk and North Milk rivers in southern Alberta. They appear to be disjunct from their conspecifics elsewhere in Canada. In November 2010, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed these populations of Mountain Sucker as a separate designatable unit (DU2) and assigned them a designation of Threatened. While there is no evidence to suggest that the Milk River populations have declined in abundance since the species was first identified there, COSEWIC considers this small, bottom-dwelling freshwater fish to be at risk due to its small area of occupancy and number of locations (eight). These conditions make Mountain Sucker particularly susceptible to habitat loss and degradation from altered flow regimes and drought that climate change is expected to exacerbate.

The Milk River populations of Mountain Sucker will be considered for legal listing under the

 

Species at Risk Act (SARA). In advance of making a listing decision, Fisheries and Oceans Canada (DFO) has undertaken a Recovery Potential Assessment (RPA) that summarizes our current understanding of the distribution, abundance, and population trends of Mountain Sucker in DU2, along with recovery targets and times. Identification of threats to both the sucker and its habitat, and measures to mitigate these impacts, are also reported. This information may be used to inform the development of recovery documents, and to support decision-making with regards to the issuance of permits, agreements and related conditions under the SARA.

COSTA RICA - Ship arrested for fishing without turtle protective devices

COSTA RICA - Ship arrested for fishing without turtle protective devices | Fisheries & Fishing Technology | Scoop.it

The National Guard Service (NGS) intercepted a boat for fishing without using the device required by law for the protection of turtles, called Turtle Excluder Device (TED).

The arrest of the ship Maria Aurelia occurred last Thursday eight miles south of the beach Bandera, in Aguirre (Puntarenas).

The boat, which had been stopped on a previous occasion for the same offense, was fishing for shrimp and various fish.

During a routine patrol, the officials determined that the Maria Aurelia –Puntarenas registered P-3011 -- did not have the device required by law that permits the release of the turtles that are caught while fishing.

The Ministry of Public Security (MPS) stated the vessel had trawling nets kept starboard and larboard without the TED device installed. Therefore, the net outlet was closed, the newspaper La Nacion reported

Prawn crews collect critical data - ABC Rural

Prawn crews collect critical data - ABC Rural | Fisheries & Fishing Technology | Scoop.it
Crews in the northern prawn fishery will have more on their mind than how many prawns they're going to catch when they return to the Gulf this week.

They've been training up to be part of a long-term scientific monitoring project to help the CSIRO.

You might think trawler crews would have enough to worry about when they're on the back deck.

But for Sharee Carton, on board the F.V. Gulf Bounty, being a part of the voluntary Crew Observer Program is one of the highlights of a job she loves.

"The scientists can't get access to these animals like we can, because they would never be able to go out and collect the specimens and to get the data.

Australia - Ocean warming and aerosols link confirmed

Australia - Ocean warming and aerosols link confirmed | Fisheries & Fishing Technology | Scoop.it

The observed warming, and preceding cooling trends are partly attributed to ocean circulation changes induced by global greenhouse gas emissions and aerosols predominantly generated in the Northern Hemisphere from human activity.

The research carried out by scientists from CSIRO and the University of NSW was published in Scientific Reports and was supported by the CSIRO Wealth from Oceans National Research Flagship,  The Australian Climate Change Science Programme and the Australian  Research Council Centre of Excellence in Climate System Science.
Tim Cowan, lead author of the study, says his group was initially interested in the three decade long cooling below the surface of the Southern Hemisphere subtropical oceans from 1960s to 1990s. "But what really caught our eye was a rapid warming of these subtropical oceans from the mid-1990s, most noticeably in the Indian Ocean between 300 m to 1000 m depth," said Cowan

Early jellyfish bloom good news for P.E.I. swimmers - Prince Edward Island - CBC News

Early jellyfish bloom good news for P.E.I. swimmers - Prince Edward Island - CBC News | Fisheries & Fishing Technology | Scoop.it

An early jellyfish bloom in the waters around Prince Edward Island this year is good news for Island swimmers.

The jellyfish along the coast bloomed around late May and early June, meaning the water during summer’s hottest months is clear of the current riding jellies.

“We haven't been seeing very many jellyfish along the beaches in P.E.I. National Parks this summer. I have heard people wondering if the jellyfish are coming soon and certainly it makes swimming in P.E.I. National Park more pleasant when they're not there,” said Barbara MacDonald, with Parks Canada.

MacDonald said Parks Canada isn't sure why there was an earlier bloom this year.

Last year, a similar jelly-free trend happened throughout the Maritimes

Catch share plan comment period extended two weeks

Catch share plan comment period extended two weeks | Fisheries & Fishing Technology | Scoop.it

In response to requests by Sen. Lisa Murkowski, R-Alaska, Sen. Mark Begich, D-Alaska, the Homer Chamber of Commerce & Visitor Center and the Alaska Charter Association, the National Oceanic and Atmospheric Administration Fisheries announced Wednesday it had extended the comment period on the controversial Catch Sharing Plan — but only by 14 days. The new comment period ends Aug. 26.

“I think it’s absolutely silly,” said chamber Executive Director Monte Davis. “We asked for enough time so that people in their busiest time of year would have time to comment on the Catch Sharing Plan.”

Begich also expressed disappointment.

“Giving Alaskans just two weeks more during the busy summer fishing season to comment on a contentious plan on how we manage our state’s halibut fishery is a disservice,” he said.

CHILE - Fish landings fall 28 per cent in the first half

CHILE - Fish landings fall 28 per cent in the first half | Fisheries & Fishing Technology | Scoop.it

Accumulated fish landings up to June 2013 totalled 1.5 million tonnes, representing 28.4 per cent less in the first six months of 2012, when 2 million tonnes were landed.

According to the latest Sector Report on Fisheries and Aquaculture of the Undersecretariat of Fisheries and Aquaculture (Subpesca), the capture sector contributed 936,000 tonnes between January and June 2013.

The 78.9 per cent of the capture sector landings consisted of pelagic resources. The landings of anchovy, horse mackerel and sardine respectively accounted for 40.4 per cent, 29 per cent and 17.9 per cent of the landings of the capture sector accumulated until June 2013.

These landings were concentrated in regions V and X (55.1 per cent of the total); regions XV and II (33.4 per cent), and regions III and IV, which accounted for 11.5 per cent of the landings.

New Calidonia - Historic record: tuna recovered after tagging it 13 years ago

New Calidonia - Historic record: tuna recovered after tagging it 13 years ago | Fisheries & Fishing Technology | Scoop.it

A tuna that had been caught 13 years ago to tag it for scientific purposes was recently recaptured off the east coast of Fiji.
The bigeye specimen had originally been tagged as part of a monitoring programme organized by the Fisheries Division of Secretariat of the Pacific Community (SPC), which started in the 1970s.
According to the scientists participating in the research, 13 years of freedom constitutes a first for the SPC.
The goal of the programme is to maintain the sustainability and health of tuna fisheries in the Pacific.
Bruno Leroy, one of the scientists working for the SPC, explains that the tagging system involves catching thousands of tuna, fitting them with a numbered plastic tag and then releasing them back into the wild. The tag records the species, the size, the tagging date, the location and the condition of each fish. This task is developed by trained teams.
“This fish is a great find,” he says. “Recovering the tags is crucial to the success of our programme because they provide information on the growth, movements, natural mortality and fishing mortality of tuna, and help us estimate the status of tuna stocks and the impact of fishing.

Spain - Tension escalates in the Strait of Gibraltar

Spain - Tension escalates in the Strait of Gibraltar | Fisheries & Fishing Technology | Scoop.it

Tension between the Government of Gibraltar and the fishermen from the Bay of Algeciras continues because the firm TP Towage has not stopped placing concrete blocks on the seabed to build a reef.

According to the major chief of the association of La Linea, Leoncio Fernandez, the incidents began when the police from Gibraltar prevented the vessel Alejandra from having access to the area where the concrete blocks are being launched, since they have iron spikes and stop fishermen from doing their usual activities.

The tension escalated with the arrival of the fishing vessel Divina Providencia.

"We’re going to claim compensation for the 53 vessels fishing in this area. They've put an end to the netters, purse seiners and trawlers," said the skipper.

"With the iron spikes that protrude from the concrete blocks, the fishing gear will be destroyed," he added, according to the newspaper El Pais.

Fishermen criticize the Spanish authorities "because they are aware of what is happening," said Fernandez.

USA - NOAA cruise to study acidification consequences on West Coast

USA - NOAA cruise to study acidification consequences on West Coast | Fisheries & Fishing Technology | Scoop.it

A team of researchers from the National Oceanic and Atmospheric Administration (NOAA) will take and study samples of plankton, water and algae to better understand how acidification is affecting the oceans ecosystems.
The team, which includes biologists and chemists, will cover the US West Coast, sailing from Seattle (Washington) on 29 July and docking in San Diego (California) on 29 August on board NOAA ship Fairweather.  
The US West Coast is particularly prone to acidification as the California Current, which runs from British Columbia to Baja California, causes deep waters rich in carbon dioxide (CO2) to interact with surface waters (also rich in CO2) so the marine ecosystems within it are affected.
