Asian Carp Surveillence

 

§         Gear – (3), 300' Trammel nets with 16" outer wall, 3.5" inner wall.

 

§         Locations – In 2004, we plan to target the waters of Ohio in western Lake Erie in areas near previous captures of bighead carp including Sandusky, Sandusky Bay, Lorrain, and Huron, OH.

 

§         Sample Dates – July? - not confirmed yet. 

 

§         Procedure – Nets will be set in the afternoon at each location and retrieved the following morning.  Each location will only be sampled once in 2004.

 

§         Fish data collected – Length, species, weight.  Asian carp (bighead or silver) will be kept and frozen.

§         Other data collected – Water temperature, DO, air temperature, depth, GPS point data, plankton samples at net locations.

Method:

          Passive gear will be used to monitor and collect Asian carp in the study area.  Passive sampling devices will include entanglement (trammel nets) and entrapment (mini fyke nets) gear.  The minimum deployment period for the passive gear will be 12-15 hours, overnight.

 

          The trammel net used in the survey is 100 feet long and 6 feet deep with a 3 ½ inch square mesh inner net, and 14 inch walling.  A ½ inch foam core float line is used at the top of the net, and a 30-pound leadcore lead line is used at the bottom.

 

          At each monitoring station, a trammel net will be deployed perpendicular to the bank.  A stationary set will be used with the net extending from the water surface to the bottom of the waterbody, in approximately 4-5 feet of water.  At Stations 1, 3, and 4, anchor the net at both ends, with the float line secured to a structure on the bank and a structure in the waterway.  Alternatively at Station 2, secure one end of the float line on the bank and use a buoy and anchor arrangement to secure the other end of the line in the waterway.  Retrieve the trammel net by untying the end of the net in the water and removing the anchor from the leadline.  Slowly pull the net out of the water into a container on the boat, removing the fish from the net.
