An Evaluation of the Wild Brown Trout Stream Fishery on the Cary Arboretum and a Discussion of Alternative Management Practices

This is a contribution to Cary Institute of Ecosystem Studies.

Abstract: Brown trout growth rates, 1980 catch and creeled/hr. rates, and WHNF habitat index values all indicate that the East Branch of Wappingers Creek (Millbrook NY) is a quality wild trout stream. Selected stream sections differed in their ability to support trout, as habitat composition, habitat quality, water temperature, insect productivity, and the relative numbers and biomass of fish species all varied. Arboretum anglers were diverse in attitudes and characteristics. Five appropriate management strategies were formulated and a multi-goal option was recommended. If implemented it would require that an appropriate section of the stream be placed under artificial lure/12 inch size limit regulations and that a nine inch size limit be maintained on the remainder of the stream. As development in the Northeast continues it will become increasingly important to manage the limited number of wild trout fisheries, whether public or private, so that they may achieve their maximum potential as recreational yet ecological resources. This will require multi-goal management with resource allocation based upon both well delineated angler attitudes and standard ecological data.
