Quinnipiac River Watershed Is Focus of Project to Improve Water Quality
Sunday, September 4, 2011
It was an exciting and astonishing season for the Menunkatuck Project Limulus team. Last year we tagged a total of 370 horseshoe crabs, so when Professor Mark Beekey of Sacred Heart University asked me how many tags I thought I could use this year, I optimistically said 600. Little did I know that I would have to request more tags twice during the season. We ended up tagging a grand total of 975 crabs!
One may conclude from this information that there were more crabs at our beaches this year. Unfortunately, this is not necessarily the case. One reason for the increase in numbers tagged was having more independent taggers this year than last year. Another reason was the extra days the group spent on the beaches during the peak of the spawning season. Between May 25th. and May 28th. we tagged 281 crabs. These were not regular survey days. A third reason why we tagged more crabs was because we had more well trained volunteers this year who were able to tag the crabs as we counted them during the survey of the beach.
Guilfordʼs Project Limulus team surveyed the two beaches at Indian Cove 24 times between May 1st. and July 1st. We also assembled at the Cove beaches 5 extra times for tagging only. We had 8 independent taggers who covered most of the beaches in Guilford. We were more likely to find crabs during the day this year than last year, but we continued to find the most at night. We counted the first crabs of the season on May 15th. The peak of the season was May 27th., when we tagged 110 in one night.
Here is the final data for the 2011 horseshoe crab spawning season:
We counted a total of 171 crabs during the 24 standardized surveys conducted at the 2 Indian Cove beaches. We tagged a total of 975 crabs at Guilford beaches including Indian Cove, Joshua Cove, Shell Beach, Chittenden Beach, Jacobs Beach, and Grass Island. We recorded 262 recaptures (crabs which have been previously tagged). Last year we only found 26 recaptures!
I am grateful to the 40 plus active volunteers for their help and enthusiasm. It was a very successful season and we had a lot of fun. I look forward to seeing all of you next year.
We are always happy to have new volunteers. If you are interested, please contact

Green Sea Turtle Found Trapped in Fishing Line
Originally mistaken for a lobster buoy, the endangered sea turtle was found with its neck and extremities bound in fishing line, covered in algae, and with a severely inflamed front and rear flipper (possibly from crab and other sea life nibbling), showing signs the turtle was trapped for a significant amount of time.

Osprey with Hook and Monofilament Line
Rescuers were called to St. Petersburg Beach regarding this osprey with a hook and monofilament line entanglement. He is able to fish and eat but if he weakens and comes down to the ground we will know it and will grab him. He is being monitored by area residents, nearby workers and volunteers.

Japanese Barberry and Lyme Disease
An article in the New London Day describes a link between the invasive Japanese barberry and Lyme disease.
Jeffrey Ward, chief scientist at the Connecticut Agricultural Experiment Station's Department of Forestry and Agriculture, and experiment station scientist Scott Williams have been doing research on the relationship between Japanese barberry, ticks that carry Lyme disease and deer overpopulation.
A highly invasive plant that forms dense canopies in forests - particularly those with high deer populations that eat most every other plant - Japanese barberry also creates moist, cool shelters that harbor ticks that carry the Lyme disease bacteria, Ward's and Williams' research has shown. Hot, dry conditions suppress tick populations.
At 28 study areas, including a parcel along Lord's Cove in Old Lyme, the two have been studying various aspects of the triangular relationship between ticks, deer and barberry, and spreading their message to land conservation organizations about the best methods for ridding forests of barberry. Deer serve as hosts for adult ticks, while the barberry functions as a nursery for ticks in their juvenile stages.
Williams said tick abundance in barberry-infested areas is 67 percent higher than those where native plants are predominant. Also, the percentage of ticks that carry the Lyme bacteria is higher - 126 infected ticks per acre versus 10 per acre in barberry-free areas, Williams said, though the reason for that is as yet unclear. After barberry removal, Ward said, tick populations drop as much as 80 percent.

King/Robinson Students Experience Raptors from A Place Called Hope
The students at King/Robinson Magnet School in New Haven experienced live raptors from A Place Called Hope Raptor Rehabilitators today. In two programs, one for the Pre-K to Grade 4 students and the other for the Grade 5 to Grade 8 students, Christine Cummings and Todd Secki brought out five birds of prey.
