"Landings of flatfish (exclusive of the halibuts) in NAFO Divisions 4VWX remained at comparatively low levels in 1985 relative to those obtained in the late 1960's and early 1970's. While landings of flatfish in 1985 have decreased by almost 35% compared with 1984, it is doubtful whether this reflects decreased stock abundance. Recent (since 1982) indications from research vessel cruises suggest relatively stable population abundances for witch flounder and American plaice, but declining for yellowtail flounder. A multiplicative analysis of catch rates for the 4V American plaice fishery revealed an increasing trend since 1983, but the standardized series (comprised of directed catch rates only), included a relatively small proportion of all 4V American plaice landings. It was therefore concluded that there were insufficient grounds to suggest a change in the existing total allowable catch of 14,000 t"--Abstract. Includes abstract in French.
