Nice video Tory. This would be a good one to show to the group at the Captains conference in March.
BTW...did the Canadians ever get us some more information on the hatch for 2013?
Thanks for all you do,

A recent news item:

Ohio seeks limits on phosphorus in streams

Ohio could become one of three states to establish limits for farm and sewage-treatment-plant pollution that feeds toxic algae in lakes.

An Ohio Environmental Protection Agency proposal under review by federal officials would establish limits for phosphorus and nitrogen in streams. Both are found in fertilizers, manure and sewage. They’re called nutrients because they help plants, including algae, grow.

Ohio EPA Director Scott Nally said he is optimistic that U.S. EPA officials will approve the proposal, which would be used to set specific limits for each Ohio stream.

It could be worthwhile to read the comments at the bottom of the news story as well
This just came across my email.  Unfortunate news.  As the release states, the grass carp are not to be confused with the silver and bighead carp, although all three species are lumped in to the "Asian carp" moniker.  Silver and bigheads would be a major blow because they feed mainly on plankton, which is the bottom of the aquatic food chain.  Grass carp feed on aquatic vegetation instead of plankton.  However, the aquatic vegetation plays an important role in the environment as well, so this is not good news and definitely bears watching. 

For Immediate Release
Oct. 28, 2013
ODNR, USGS Collaborate
on Grass Carp Study      
ODNR develops tactical plan
to address threats from invasive carp
COLUMBUS, OH – The Ohio Department of Natural Resources (ODNR) and the U.S. Geological Survey (USGS) collaborated on a USGS study released this week on the origins of grass carp caught in the Lake Erie basin. The study analyzed four grass carp provided by commercial fishermen to ODNR from Ohio’s Sandusky River and concluded through bone analysis that the fish were at least one year of age and likely produced through natural reproduction in the Lake Erie basin.
Grass carp eat aquatic vegetation, and there is concern that should the species spread, they could impact fish and waterfowl habitat through aquatic plant removal. The ODNR Division of Wildlife is actively engaged in discussions with the Asian Carp Regional Coordinating Committee, U.S. Fish and Wildlife Service (USFWS), USGS, Great Lakes states as well as Fisheries and Oceans Canada and the province of Ontario about next actions to address knowledge gaps about grass carp population status in the Great Lakes, evaluate risk from this species and potential to develop integrated pest management strategies to control impacts of feral, naturally reproducing grass carp.
"Grass carp are considered an Asian carp but should not be confused with bighead and silver Asian carp,” said ODNR Division of Wildlife Fish Administrator Rich Carter.
Bighead and silver carp are threatening to invade the Great Lakes from the Mississippi River Basin, and extensive effort is directed at closing the connections between these basins. Bighead and silver carp compete with native fishes for microscopic plankton and compromise the quality of sport fishes.
Grass carp have been stocked across the U.S. since the 1960s. Feral (wild) grass carp have been documented from numerous locations in the Great Lakes and Lake Erie since the mid-1980s, but ploidy status (sterile versus fertile) has not been tested until recently. Feral grass carp have been collected in the Ohio River watershed since 1980. Reproducing populations exist in the lower Ohio River. Recent research documented fertile (diploid) grass carp in Lake Michigan and Lake Erie at Monroe, Mich.
Ohio and 42 other states allow the sale of sterile (triploid) grass carp that are used for controlling aquatic vegetation in ponds. Ohio law does not allow importation or stocking of fertile (diploid) grass carp. Ohio law has allowed importation and stocking of certified sterile (triploid) grass carp since 1988. A certification program is administered by USFWS.
ODNR has developed an Ohio Asian Carp Tactical Plan that provides detailed approaches to address the threats by bighead, silver and grass carp. The plan is currently being finalized incorporating stakeholder comments. ODNR’s strategies to address grass carp outlined in the plan include:
•   Statewide testing of fish collected in ODNR assessments to determine fertility.
•   Random testing of certified triploid grass carp for fertility status in Ohio shipments.
•   Enforcement of prohibitions on diploid grass carp importation.
•   Engaging regional partners in discussions on grass carp use and threats/risk assessment.
ODNR ensures a balance between wise use and protection of our natural resources for the benefit of all. Visit the ODNR website at

Here is a handy little video that came across my email this morning.  Live bait is a potential vector for the spread of many invasive species, and Asian carps are an example.  This video gives some tips on how to identify juvenile Asian carps compared to common bait species.

And remember, never dump your unused bait in the water!  Whether it came from the bait shop or a different body of water, it has the potential to spread aquatic invasive species.  The best way to dispose of unwanted bait is to dump it in the trash, or on land, far enough away from the water that the critters can't reach it.  For more information, check out the Stop Aquatic Hitchhikers! website.

As always, good luck out there.
Just FYI-

Here's an opportunity for your voice to be heard for those of you that enjoy outdoor recreation.

Hi Jim,

Nothing concrete from Ontario, but from all the data they have it appears the Ohio numbers are accurate.  Decent yellow perch hatch, a little below average for the walleye hatch.

     Have there been any further updates on the walleye hatch since your post on Sept. 6th?  If not, when does Ontario generally make their surveys public?

Preliminary numbers from Ohio are coming in, and I stress both "preliminary" and "Ohio". 

So far there is evidence of a decent yellow perch hatch, and a slightly less than average walleye hatch.  If that holds true, "slightly less than average" would be better than the past five years, aside from 2010 which was pretty much average.   

However, they are still waiting for other agency data, and then they will need to crunch the numbers.  It will be later this fall until we know the real story here. 
Thanks for sharing David.

Also of note is the draft Lake Erie Protection & Restoration Plan (LEPR), released by the Ohio Lake Erie Commission. This document reflects actions the Ohio Lake Erie Commission and its member agencies plan to take over the next several years to protect, preserve and restore Ohio’s Lake Erie. The state’s actions complement federal and local partners’ initiatives in the Lake Erie basin and across the region.

The plan highlights 12 priority areas, several of which address Harmful Algal Blooms (nonpoint source pollution, coastal health, and indicators and information). The public comment period has closed and the final draft should be published later this year.

The IJC has recently, 2013/08/29, released a report concerning the Harmful Algal Blooms (HABS) and nutrient loading for Lake Erie. And are also requesting public comments. Below is a few details pulled from the IJC website. Use the links below for full details.

The International Joint Commission (IJC) is an international organization created by the Boundary Waters Treaty, signed by Canada and the United States in 1909.

The International Joint Commission prevents and resolves disputes between the United States of America and Canada under the 1909 Boundary Waters Treaty and pursues the common good of both countries as an independent and objective advisor to the two governments.

Draft Report
Commission Seeks Public Comment on Draft Lake Erie Report
Report Provides Advice to Governments to Reduce Nutrient Loadings and Harmful Algal Blooms
Brief report

Full report


Open Houses
Unless otherwise noted, each open house will have a poster display from 6-7pm with a time for public comment from 7-9pm.

The complete report can be reviewed at .
A few key highlights are:

-Current phosphorous loads to Lake Erie are largely from non-point sources.

-Run-off from agricultural sources such as fertilizer and animal waste are a major non-point source of phosphorous.

-There are hotspots that contribute a disproportionate share of dissolved reactive phosphorous (DRP) that is more bioavailable for supporting algal growth.  The single biggest source of DRP is the Maumee River.

-Because of the intense storms related to climate change, future nutrient loading, coupled with warmer temperatures, could lead to increased severity and frequency of algal blooms.  Climate change may also contribute to increasing hypoxia (dead zones) in the central basin of Lake Erie.

-In the western basin of Lake Erie, types of algae known as Microcystis and Anabaena both can secrete toxins that kill wildlife and pose a risk to human health.

-Phosphorous monitoring is inadequate, especially with regard to wet weather events as well as the share of phosphorous loading to Lake Erie contributed by the Detroit River.

With respect to action, the Commission made 15 specific recommendations directed toward federal, state and provincial governments.  These include:

-To reduce the severity and extent of harmful algal blooms to acceptable levels, governments should set total phosphorous load targets for the Maumee River and the western basin of Lake Erie that are roughly 40 percent below the average loads for the past five years.

-To reduce the hypoxic area by half, the DRP load should be reduced by more than 75 percent compared to the average.

-All jurisdictions in the Lake Erie basin should ban the application of manure and biosolids from agricultural operations on frozen or ground covered by snow.

-All jurisdictions in the Great Lakes basin should prohibit the use of P fertilizers for lawn care with strictly limited exceptions.

-Future management efforts should focus on reducing the phosphorous load delivered during the spring period and be focused primarily on those subwatersheds that are delivering the most phosphorous into the lake.

-Existing and planned incentive based programs should immediately shift to a preference for Best Management Practices that are most likely to reduce DRP.

-The U.S. & Canadian governments should strengthen and increase the use of regulatory
mechanisms of conservation farm planning, with nutrient management as a primary emphasis, in balance with the economic viability of the sector.

-U.S. and Canadian federal policy should link the cost and availability of crop insurance purchases or premiums to farm conservation planning and implementation of nutrient management practices.

-Governments should commit sustained funding for enhancing and maintaining monitoring networks, especially a water quality monitoring system at the outlet of the Detroit River and monitoring during wet weather events.
