LANSING, Mich. (AP) — The fishing openers last weekend were slow, but catch rates should pick up as warmer temperatures push into the state, the Michigan Department of Natural Resources said Wednesday in its weekly fishing report. The DNR said water levels are low in some of the rivers and inland lakes so use caution especially at the boat launches. Read more …

 

Governor Scott Walker has signed the so-called Aquaculture Bill into effect this month. Members of the Wisconsin Aquaculture Association say the measure has significant features for the state’s fish farming industry.

As part of the new policy, natural water body permits do not expire unless the state determines that there has been a substantial change in circumstances. There will be confidentiality of records relating to information kept by the Wisconsin Veterinary Diagnostic Laboratory relating to identification of fish farms or testing results except if the laboratory determines it is necessary to protect public health, safety or welfare.  Read more …

 

Now’s the time to begin planning to attend AES Issues Forum August 23, 2012 And 9th International Conference on Recirculating Aquaculture August 24 – 26, 2012 At The Hotel Roanoke and Conference Center, Roanoke, Virginia, USA.

Early Registration is now open

You are invited to participate in the AES Issues Forum (August 23, 2012) and the 9th International Conference on Recirculating Aquaculture (ICRA) (August 24-26, 2012), both taking place at The Hotel Roanoke and Conference Center in Roanoke, Virginia.

The AES Issues Forum focuses on engineering solutions to specific aquaculture challenges.  The biennial International Conference on Recirculating Aquaculture offers a wider scope of aquaculture-related topics including research, enterprise, and discovery; unique opportunities for discussion; and the chance to explore new products and technologies in our trade show.

The two meetings have been scheduled back-to-back to maximize the efficiency of your travel budget.  Join your colleagues in industry, government, and academia to share your successes and learn all about the latest advancements in the field.

Have you considered being an exhibitor at the trade show or becoming a conference sponsor?  For more information go to http://www.recircaqua.com/tradeshow.html.

Don’t let 2011 fool you — Lake Michigan’s fisheries could be perilously close to a very bad day.

That’s the message of Department of Natural Resources biologists and the subject of a meeting scheduled for later this month where deep stocking cuts to salmon and other gamefish species will be discussed. The public meeting is from 1 to 4:30 p.m. April 14 at Lake Michigan College in Benton Harbor. Read more …

 

Last week, the Michigan Department of Environmental Quality (DEQ) announced that the draft Aquatic Invasive Species State Management Plan is available for public comment, and a public meeting is scheduled in April to discuss the draft plan.

The AIS State Management Plan details existing and proposed strategic actions needed to prevent the introduction and spread of AIS, and to limit the harmful effects in Michigan waters. Invasive species negatively impact Michigan’s aquatic ecosystems, creating environmental and economic consequences.

Michigan’s original AIS State Management Plan was completed in 1996 under the auspices of the National Invasive Species Act, and last updated in 2002. It offers a comprehensive strategic guide for state agencies charged with responding to existing invasive species and preventing the introduction of new ones.

Where the original plan focused largely on responding to specific invasive species, the draft update announced today places stronger emphasis on blocking pathways of AIS introduction and spread. Strategies for the early detection of AIS and rapid response actions to manage them are also included in the draft plan.

The draft management plan update is a collaborative effort involving several state agencies, including the DEQ and state departments of Natural Resources, Agriculture and Rural Development, and Transportation. Plan authors solicited input from partners and stakeholders to identify gaps and strengthen the overall plan. Feedback received from previous public meetings and comment periods in 2008 and 2009 also contributed to the current plan.

A public meeting is scheduled April 12 at the Best Western Plus in Lansing, from 12:45 – 4:45 p.m. This meeting will provide more background on the AIS State Management Plan and give interested parties the opportunity to provide feedback and comments.

The meeting is open to the public and intended for anyone with a vested interest and/or concern for AIS issues in Michigan. Breakout sessions will provide participants the opportunity to share comments on AIS issues associated with boating and ballast water, organisms in trade and habitat alteration, AIS management and control, and early detection and rapid response. While there is no fee to attend the public meeting, advance registration is requested.

The draft AIS State Management Plan is available for review here.

The Web site also offers additional meeting details and instructions for submitting comments, which are accepted through May 1. For more information, contact Sarah LeSage of DEQ’s Water Resources Division at lesages@michigan.gov.

Abstract submission deadline is Monday, April 16, 2012 at 11:00 pm CST

The purpose of UMISC 2012 is to exchange information on invasive species topics. This is an all-taxa conference covering invasive aquatic and terrestrial plants, animals, pests, and pathogens. The foci are to 1) strengthen awareness of invasive species issues, prevention, and management; and 2) facilitate information sharing and collaboration among researchers, land managers, natural resource professionals, university personnel, landscapers, nursery, agricultural or forestry employees, environmental specialists, lake association members, land owners, governmental agencies, nongovernmental organizations, and others interested in controlling the spread of invasive species in the Upper Midwest.

The host organizations are the Invasive Plants Association of WisconsinMidwest Invasive Plant NetworkMinnesota Invasive Species Advisory Council, and Wisconsin Council on Invasive Species. We expect participants to come from across the Midwest region, including Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, and Wisconsin. 

CONFERENCE SESSIONS WILL FOCUS ON: 

Invasive Species Biology, Ecology, Impacts, and Distribution
Biology, Ecology, Impacts, and Distribution of Invasive Species. 

Invasive Species Prevention
Risk Assessment, Outreach and Education, Regulation, Available Technology, Containment of Established Invasive Species, Proactive Industry and Agency Procedures, Proactive Land Management Practices, Emerald Ash Borer Preparedness, and Silvicultural Research

The 2012 NCRAC Annual Program Planning Meeting was held in East Lansing, MI, last month. For those of you not familiar with this program, NCRAC (North central Regional Aquaculture Center) is one of five Regional Aquaculture Centers administered by the U.S. Department of Agriculture’s National Institute of Food and Agriculture (NIFA). These centers work together within the broader, integrated aquaculture program of USDA to promote a well developed and sustainable aquaculture industry in the United States.

NCRAC consists of an Industry Advisory Council (IAC), made up of industry representatives from 12 states in the North Central Region (NCR), a Technical Committee (TC) from among academia and state agency personnel, and Board of Directors.  The purpose of the Annual Program Meeting is to select priorities for the upcoming funding cycle made available through USDA.

This year’s project selection process resulted in the following priorities:

  • Regional Aquaculture Extension
  • NCRAC Base extension
  • Early survival of yellow perch fry and larva in intensive indoor systems
  • Developing genetically fast-growing monosex male bluegill sunfish

Calls for Statements of Interest will be distributed to the NCR aquaculture community in the near future (typically 6-10 weeks).  Statements of Interest can be submitted by individuals or groups within the community on an open basis.  Preference may be given to groups extending to two or more institutions and/or states.  After a vetting process and final approval by NIFA, workgroups selected typically begin their projects in September the following year (9/14 in this case).
