Greg :

Sorry I misunderstood your post. :rolleyes: You ask about the enclosure and I thought you were talking about the enclosed (discussed) study.

Part of the study was in the lab so the type of enclosure was not applicable to ponds. The rest of the study was lake observations where thick brush to thin brush to open water was observed.

I have placed thick brush in several coves and use a blocking net on one cove in our ponds.

I have thought about an easy portable way to make a safe area and enclosure to shelter fish as per the article. My idea is to buy 4 pieces of rigid plastic fencing/net 6 ft. long by 4 ft high. with 1/4in. holes (much like a std. seine net). It is fairly cheap about like seine net. Then attach to the bottom w/ epoxy and or plastic ties about 4 8in. tent stakes to each piece. ID the location to be used and in 3 ft of water add brush around an open area of 8 x 8. When ready to stock then stick the 4 panels into pond bottom in open area to form an enclosed square and use D rings to attach top of 4 panels to each other. All the enclosure has to do is keep out big fish for a short time (+- 1 hr.). After your selected time is up take off D rings pull up panels and add some brush to the open area and you are done. I think this could also be done with a 40 ft standard seine and 4 stakes. Use stakes to form corners of area and place seine around them and tie end poles of seine together. After selected time remove seine and add brush to open area. I am sure there are other ways as well. ewest
