Hammerschmidt, P.C.Benefield, R.L.2010-02-152010-02-151986http://hdl.handle.net/1969.3/215787 pgs.The number and distribution of crab traps fished in Texas bays was determined by aerial surveys conducted during fall - spring 1977-1978 and fall 1985. The mean number of traps counted on a given day in 1977-1978 was about 6000. The number ranged from 3574 in winter to 6967 in fall. Data indicated that between 1967 and 1977 crab fishing effort expanded from the upper and middle Texas coast to include the lower coast. A 1985 followup survey indicated that fishing effort increased about 64% (11,189 traps) from the 1977 survey, and crab traps were observed in each bay system.crab fisheriescrabsblue crabCallinectes sapiduscagesfishery managementfishery surveysaerial surveysBook
