The impact of improving fishing gear technology on the fisheries resources
Since man first caught a fish he has strived to catch them more efficiently and in greater quantities with less effort. The way the fishery is prosecuted in Newfoundland and Labrador has been evolving for over 500 years, but the most sweeping changes have occurred during the past 100 years. Theses c...

Since man first caught a fish he has strived to catch them more efficiently and in greater quantities with less effort. The way the fishery is prosecuted in Newfoundland and Labrador has been evolving for over 500 years, but the most sweeping changes have occurred during the past 100 years. Theses changes, or "improvements", can be divided into three (3) areas: 1) fishing gear technology, 2) vessel design, and 3) electronic aids. This paper examines the effects of improving fishing gear technology with emphasis on the negative and positive effects these changes have had on the abundance of fish stocks harvested in the Newfoundland and Labrador Region. -- The primary species harvested in the Newfoundland and Labrador region at the tum of the century was Atlantic cod (Gadus morhua).
