These landings of so-called 'trash fish" have excited the interest of menribers of the fishing industry since that time. Since the beginning there have been many complaints from sportsmen and fisherinen to the effect that large quantities of valuable food species, particularly the yellowtail flounder, were being utilized for animal food. Others claimed that excessive quantities of small fish of various other species were likewise being wasted. In order to clarify the situation and help to settle the considerable amount of discussion about the industry, research on the fishery was started .jt Woods Hole with Saltonstall-Kennedy funds in 1955. Initially, the project was primarily concerned with the effect of the fishery on the yellowtail flounder. Much of the original controversy now appears to have been unwarranted while other problems, equally serious but not so obvious, have come to li.ght. Many of the species involved merited study and accordingly the research emphasis was shifted to a study of the species complexes involved in each major fishing area and to the significance of hydrography on their structure. In addition, a compre- hensive life history study of the red hake, the mainstay of this fishery, wns begun. Until 1957, the greater part of the Nev/ England landings were mnde at Ft. Judith from the fishing grounds off southern New England. In 1957, due to the marked decline of the menhaden population in the Gulf of Maine, there was a notable increase in industrial trav/1 fish landings at Gloucester. In the event that a relatively stable industrial fleet develops at Gloucester, it is felt that the overall landing for New England could easily double in the next few years. The landings with which we are concerned here are those made by vessels that are fishing a population wholly or in part for fish for reduction. This report is not concerned with those occasional trips of spoiled food fish that are sold for reduction, or those occasional trips of food fish sold for reduction because a skipper is not satisfied with the market price. The former situation occurs at all ports, the latter principally at Gloucester in connection with the silver hake fishery. In the main this fishery is a split fishery in that vessels land both fish for reduction and fish for food. In general terms, the southern New England industrial trawl fishery is based on a flounder economy and the Gulf of Maine fishery is based on a silver hake economy. The present report is concerned solely with presenting an estimation of the landings of the various species involved at the principal New England ports. In 1957, the landings totaled about 168 million pounds, by port as follows- Gloucester, 37 million pounds. New Bedford, 42 million pounds, and Point Judith, 89 million pounds. For a summary of New England landings prior to 1957, see Edwards and Lux 1958. For general information on the Pt. Judith fishery, see Interim Report: The Flounder and Industrial Fishery Project.^' For a detailed discussion of this fishery at Gloucester, see Edwards 1958.2/ REMARKS ON THE SAMPLING PROCEDURE At Pt. Judith, the catch is normally sampled by forking fish out of a conveyor belt as the fish are transported from the vessel to the reduction plant. Fish to be sampled are similarly obtained at New Bedford, but at Gloucester the catch is sampled from a dump truck. Proper precautions are taken to assure that the samples are not taken from mixed area trips. Complete interviews are made of all trips as far as possible, sampled or not. 1-/ Interim Report: The Flounder and Industrial Fishery Project. Multilithed report prepared by R. L. Edwards for the Annual Meeting of the Point Judith Fishermen's Cooperative Ass'n , Inc. , February 10, 1956. Available on request from North Atlantic Fishery Investigations, Woods Hole, Massachusetts. 2 / — ' Edwards, Robert L. 1958. The Industrial Trawl Fishery at Gloucester. Manuscript. Usually, the fish in each sample are counted and weighed by species. At intervals, all the individual fish in the sample are measured to obtain length frequency information. Sample size is usually one bushel although occasionally a two bushel sample is taken so that adequate numbers of individual species are present for length frequency information. It has been determined that a one bushel sample is an adequate representation of any single vessel's load for all species present that make up over 10% by weight of the catch. The increase in sample reliability in a two bushel sample for species composition by weight analyses does not justify the additional labor at this time. For the purposes of this report, it is presumed that the samples are sufficiently reliable to indicate the seasonal trends and relative amounts of the different species landed within - 5% for all those species representing 10% or more by weight of the catch. Those species present in quantities amounting to less than 10% of the catch are not reliably sampled and the limits of confidence are very broad. However, it is felt that the general picture presented is more than accurate enough for the purposes of those interested in what this fishery lands for reduction. An extended analysis of sample reliability will be published later in connection with other studies. As far as possible, only samples taken in 1957 were used. In some cases, however, the breakdown was made with information based on samples taken in 1955 and 1956. The tables are annotated accordingly. Samples taken at one port may be used in an analysis of another port's landings; it is the fishing area that we are concerned with when we take the sample. The port of landing obviously has no significant effect on the species composition. POINT JUDITH LANDINGS To obtain as accurate figures as possible, the Pt. Judith landings are broken down into three general groups by area: landings from the No Man's area, landings from those local grounds with depths of less than 25 fathoms and referred to as the inshore area, and landings from local grounds with depths of greater than 25 fathoms and referred to as the offshore area. Only 1957 sample data was used for the inshore and offshore areas. For the No Man's breakdown, the data for the last three years has been combined. There has been no significant changes in the percentages from one year to the next in this particular area. Interview information on the fishing grounds was available for over 90% of the trips. The uninterviewed trips were assigned to one of the three areas according to the distribution of interviewed trips. NEW BEDFORD LANDINGS Interview information on the landings at New Bedford indicates that about 90% of the trips landed are from No Man's. Approximately 50% of the New Bedford trips were interviewed. The entire landings were therefore broken down with the data obtained from No Man's samples. In view of the great similarity of the other local fishing grounds, only a very negligible error, if any, is introduced by this action. GLOUCESTER LANDINGS The Gloucester landings originate from three general areas, referred to here as the Ipswich area, Nauset, and Stellwagen Bank. Since these areas differ considerably as far as the fish landed are concerned, the data is broken down accordingly. Approximately 90% of the trips landed at Gloucester were interviewed. A number of pure trips of silver hake were landed for reduction at Gloucester. These figures are not available, except for August, when an estimated 7 35, 000 pounds of silver hake were landed for reduction from Stellwagen Bank. The Gloucester vessels will frequently fish two or more grounds during any one trip. Even with the excellent interview information available, a considerable amount of prorating was necessary. Thirty-seven percent of the trips were multiple area trips. CATCH-PER-TRIP DATA A table is included indicating the number of interviewed trips to each ground at Pt. Judith and Gloucester and the average catch per trip. The catch-per-trip data are based on interviewed single area trips so that it may serve as a rough index of abundance. It will be noticed that number of trips used in the calculations for the three Gloucester grounds is far less than the total number of trips for Gloucester for any one month, because the Gloucester vessels have a strong tendency to fish on two or more grounds during any one trip.
