Assessing the feasibility of winter
flounder, Pseudopleuronectes americanus, stock enhancement.
Although, winter flounder support signficant recreational
and commercial fisheries in the Gulf of Maine, stocks have delined precipitously
in the past two decades. This decline mainly has been attributed to overfishing.
While there are now stringent fishing regulations in place to help rebuild the
stocks, it still could take many years for them to reach their historic levels.
It is possible that stock enhancement could expedite this recovery.
The goal of my research is to initiate an investigation to determine if it is
possible to stock winter flounder successfully in New Hampshire. Because the
planning of any new enhancement program is so complex and multi-disciplinary, I
have chosen to focus on only one area - developing optimal release strategies
for a winter flounder enhancement effort.
My research is conducted both in the laboratory and in the field.
Each year I collect a wild broodstock, spawn them in the lab, and raise the
offspring. Experiments begin when the progeny reach the juvenile stage.
Questions that I am investigating are:
- What size winter flounder should be released in an enhancement program?
- Where should releases occur?
- When should releases occur?
- How "fit" are the cultured fish?
- Are the cultured fish more vulnerable to predation than wild fish?
- What pre-release conditioning do the cultured fish require?
- What tags are best for the juvenile fish?
