EXECUTIVE SUMMARY

A sport fishing survey was conducted on the upper Niagara River from April 5 through November 30, 2003.  The objectives were to estimate the number of hours fished, the number of fish caught and harvested, catch rates, and harvest rates for both shore and boat anglers.  Data on fishing from boats were collected from 35 weekly aerial counts and from interviews with 379 boat angling parties at a combination of eight boat ramps and marinas.  Data on fishing from shore were collected from counts of anglers and 5,124 anglers interviewed representing 3,072 fishing parties at 15 public access sites along the river.

Boat anglers made an estimated 16,741 trips to the upper Niagara River and spent an estimated 65,050 hours fishing. Seasonally, the greatest number of the trips (54%) and hours spent fishing (56%) occurred during the summer.  More boat trips were made to the Tonawanda Channel (6,880) than to the Chippewa Channel (4,219) or mainstem of the Niagara River (5,642).  Among boat anglers who fished for a particular species rather than anything they could catch, smallmouth bass was most frequently sought, followed by muskellunge and northern pike.  Boat anglers fished for smallmouth bass and muskellunge primarily during the summer and fall and for northern pike primarily during the spring.

 Shore anglers made an estimated 44,854 trips to the upper Niagara River and spent an estimated 91,530 hours fishing. Seasonally, the estimated greatest number of the trips (47%) and hours spent fishing (47%) occurred during the summer.  Most of their trips were to Ferry Street (Broderick Park), Squaw Island, and Ontario Street; 71% of the trips were to Buffalo waterfront sites. Unlike boat anglers, most shore anglers (70%) fished for whatever they could catch rather than a particular species.  Among shore anglers who fished for a particular species, black bass (primarily smallmouth bass) was most frequently sought, followed by yellow perch and northern pike.  Shore anglers fished for black bass (primarily for smallmouth bass) during all seasons and for yellow perch and northern pike primarily during the spring and fall.

The catch rate of yellow perch by boat anglers seeking yellow perch during 2003 was 4.68 fish/hour for the period April 5 through November 30 and 4.02 fish/hour for the period May 18 through November 30, i.e., the period when boat anglers were interviewed during a 1999 survey.  The catch rate during the 1999 survey, based on anglers interviewed in New York only, was. 5.20 fish/hour. The catch rate of yellow perch by shore anglers seeking yellow perch during 2003 was 4.11 fish/hour for the period April 5 through November 30 and 3.20 fish/hour for the period July 23 through November 30, i.e., the period when shore anglers were interviewed during the 1999 survey. The catch rate of yellow perch during the 1999 survey was 5.11 fish/hour.   

The catch rate of smallmouth bass by boat anglers seeking smallmouth bass during 2003 was 0.84 fish/hour for the period April 5 through November 30 and 0.79 fish/hour for the period May 18 through November 30, i.e., the period when boat anglers were interviewed during a 1999 survey.  The catch rate during the 1999 survey, based on anglers interviewed in New York only, was 0.90 fish/hour. The catch rate of smallmouth bass by shore anglers seeking smallmouth bass during 2003 was 0.55 fish/hour for the period April 5 through November 30 and 0.49 fish/hour for the period July 23 through November 30, i.e., the period when shore anglers were interviewed during the 1999 survey. The catch rate of smallmouth bass during the 1999 shore survey was 1.64 fish/hour.  

The catch rate of northern pike by boat anglers seeking northern pike during 2003 was 0.45 fish/hour for the period April 5 through November 30 and 0.45 fish/hour for the period May 18 through November 30, i.e., the period when boat anglers were interviewed during a 1999 survey.  The catch rate during the 1999 survey, based on anglers interviewed in New York only, was 0.25 fish/hour. The catch rate of muskellunge by boat anglers seeking muskellunge during 2003 was 0.07 fish/hour for the period April 5 through November 30 and 0.07 fish/hour for the period May 18 through November 30, i.e., the period when boat anglers were interviewed during the 1999 survey. The catch rate of muskellunge during the 1999 survey was 0.08 fish/hour.  

Overall CPUE for the boat fishery was 1.08 fish/h, with angler success higher during spring than during other seasons.  The overall HPUE was 0.13 fish/h as boat anglers released a high proportion of fish caught.  Overall CPUE and HPUE for the shore fishery was 2.10 and 0.90 fish/h, with angler success and harvest higher in the fall than in other seasons.  The largest components of total CPUE and HPUE by shore anglers resulted from success catching yellow perch, round goby, smallmouth bass, and rock bass.

Boat anglers caught an estimated 71,126 fish, 85% of which were smallmouth bass, largemouth bass, yellow perch, and northern pike, and harvested an estimated at 9,457 fish, 78% of which were smallmouth bass and yellow perch.  Catch and harvest of smallmouth bass peaked during summer while catch and harvest of yellow perch peaked in the fall.

Shore anglers caught an estimated 185,637 fish, of which most were yellow perch, round goby, rock bass, and smallmouth bass, and harvested an estimated 79,040 fish, with more than half the harvest consisting of round goby that were typically discarded by the anglers. Yellow perch and rock bass formed the bulk of the remaining fish harvested for personal use.  Although 24,353 smallmouth bass were caught, only 1,617 were harvested.  Catch and harvest of round goby and smallmouth bass peaked in summer, while catch and harvest of yellow perch peaked in spring and fall.  Catch and harvest rock bass was highest in spring and summer.

About 95% of all anglers interviewed resided locally, i.e., in Erie County, Niagara County, or nearby portions of the five adjacent counties; most of the others were from out-of-state.
