11 INRODUCTION The Jacquet River, a medium sized salmon stream approximately 50 km in linear length in Restigouche Co., New Brunswick contains ideal spawning and rearing habitat for Atlantic salmon (salmo salar). With theexception of logging activity, the watershed is largely undeveloped. In 965, Brunswick Mining and Smelting, Ltd. installed a water intake structure approximately km from themouth of the Jacquet River. They are presently operating on a water license from the New Brunswick Department of Fisheries and Environment (now the N.-B. Dept of Municipal Affairs and Environment). This license, renewed in 974, expiring in 979 and not since renewed. entitles them to withdraw 9 cu. meters/day for their consumption in the lead smelter and the fertilizer plant as weu as for domestic use in two adjacent town sites in BeUedune. Five previous studies of the river have been undertaken within the last twenty years. Three were qualitative in scope offering visual descriptions of available habitat and fish present (Smith-956, N.B.D.N.R. (unpublished 969 report), and IEC Beak 984). Two studied the micro-habitat requirements of salmon in the area downstream from the water intake station (Marantz 98, IEC Beak 98). None of these studies presented quantitative data for water or sediment quality or hydrology. In August, 984, the Gulf Region's Fish Habitat Division conducted a survey on thej acquetriver to determine sitespecific baseline conditions for hydrology, water chemistry, sediment chemistry, fish and macro-invertebrate populations, and habitat quality. The area of study consisted of 4 sites along the main stem of the river and seven of its major tributaries: Big Hole Brook, Antinouri Lake Brook, Lower South Branch, Lower McNair Brook, Upper South Branch, Upper McNair Brook and Rocky Brook. This report, the fourth in a series of four data reports, presents the benthological data collected on the survey. MATERIALS AND METHODS Benthic macro-invertebrate sampling within the Jacquet River Watershed was conducted at study site locations selected according to criteria described in Volume of this series. A Surber sampler was used for benthic macro-invertebrate sampling in streams and an Ekman dredge was used at one lake site. nylon net with mesh openings of 04 microns. The brass frame confines an actual sampling area of.09 m Three Surber samples were collected from each of 6 stream study sites. Each sampling station was considered to be typical of benthic invertebrate habitat and had adequate stream flow to permit effective operation of the sampler. The sampler was placed on the stream substrate and firmly held in position while substrate within the brass frame was cleaned for a period of 60 seconds, auowing benthic invertebrates and organic material to detach from the substrate and drift into the net. Contents of the net were then washed into a pail having a screened bottom, transferred to 500 ml polyethelene bottles and preserved in a 0% formaldehyde solution. Three Ekman dredge samples were collected at selected sampling stations at one lake. The Ekman dredge, supplied by Wildco consists of a box-like device with two clam sheu jaws containing a chamber volume of 540 cm (volume of sample). Secured samples were washed through a screened tub, transferred to 500ml polyethelene bottles and preserved in a 0% formaldehyde solution. Preserved samples from stream and lake study sites were sorted in the laboratory with the aid of a Wild M dissecting microscope. In this procedure, benthic macro-invertebrates were removed from detritus and organic material in the sample and preserved in labelled glass vials with a 0% formaldehyde solution. Preserved invertebrate specimens were then transferred to the Atlantic Reference Centre of the Huntsman Marine Laboratory in St Andrews, N.B. and identified to species, where possible, using criteria descibed by Bednarik and McCafferty, (979), Pennak (95), Merritand Cummins (984), Simpson and Bode (980), Ward and Whipple (959), and Wiggins (977). RESULTS Relative abundance of each species was compiled and tabulated for each sample from au represented sites and presented in this report. Insects, which comprised the majority of invertebrates sampled, are listed at the beginning of each table and fouowed by taxa of the remaining organisms which include amphipods, annelids, molluscs and turbeuarians. The Surber sampler supplied by Wildco (Saginaw Mi.,-U.S.A.) consists of hinged brass frames attached to a
