<br />1996 Paria River Native Fish Monitoring <br />Methods <br /> <br />Seine hauls were conducted using a 4.6 x 1.8 m straight seine with a 4.8 mm nylon mesh <br />at Sites 1 - 9. Site 10 was sampled using a 10.0 x ].S m bag seine with a 1.8 x 1.8 x 1.8 m bag <br />with 6.4 mm mesh. Only one seine haul was made at each site, with the exception of Site 10, at <br />which from 1-5 hauls were made. <br />Fish were identified to species, measured for total length (TL; mm), weighed (0.0 g) and <br />released alive at site of capture. All native fish > 150 mm TL were scanned for the presence of a <br />PIT tag. If no tag was present, one was inserted into the fish. PIT tag numbers were recorded <br />for all fish. <br />abitat <br />Habitat data were collected at a representative location within each sampling site. Depth <br />(cm; maximum and representative), velocity (cm/s) and temperature (°C) were recorded at all <br />sites sampled. <br />Results <br />Fish Collections <br />A total of 859 fish of four species was caught in the Paria River in 1996. Speckled dace <br />(Rhinichthys osculus) was the most common species caught, comprising 59.9 % (5l 5) of the <br />catch. Flannelmouth sucker comprised 39.7 % (341) of the catch. Two golden shiner <br />(Notemigomrs crysoleucas) and one rainbow trout (Onchorynchus mykiss) were also caught, <br />comprising < 1% each. The majority (336; 98.2 %) of flannelmouth suckers were caught at RK <br />0.0 (the mouth), whereas only five were caught upstream: three at RK 2.6 and two at RK 3.0. <br />Speckled dace were caught in substantial numbers throughout the entire river reach sampled, with <br />the highest catch at RK 0.0 (284) and lowest at RK 1.0 (9). <br />Flannelmouth Sucker <br />The majority of flannelmouth suckers caught were young-of--year (YOY), with only 17 <br />adults being caught. Mean length of flannelmouth suckers caught was 57.2 mm TL and mean <br />weight was 81.4 g (Table 2). <br />• <br />Brooder and Hoi~agle, 1996 Aimual Rzport Arimna Game 8z Fish Departmait 3 <br />
