Dept. of Fisheries of Canada St. John's, Nfld DEPARTMENT OF FISHERIES OFCANADA (Newfoundland Area) NEWFOUNDLAND FISHERIES IN 1962 The Newfoundland fishery in 1962 has ended at a higher level than in 1961. Total landings of all species are estimated at 544 million pounds, an increase of 8 percent over last year. The estimated landed value to fishermen, $16.9 million, is the highest on record and represents an 11.5 percent increase over last year's figure. Higher prices were generally paid to fisher- men for most species, particularly cod (salted and fresh) and haddock. In the primary industry there was an increase in the number of both inshore and offshore fishermen. Two new trawlers were added to the offshore fleet while several additional long- liners and a number of new motor boats also entered the fishery. Developments in the secondary industry were spear- headed by the highest output of frozen fish on record and by the opening of three new freezing plants. It is also worthy of note that there was an increase over the previous year in light salted fish production. Despite less favourable weather, landings were con- siderably higher than during the previous season. The cod trap fishery opened as usual early in June and closed at the end of August. On the whole the inshore fishery is considered to have been fairly good. Landings continued at a higher level than last year until August when the normal decline was greater than usual, caused mainly by the lack of squid bait and poor weather. Squid did not appear in the normal producing areas but trawl and hand line fishermen had some success with herring and caplin bait. However, in the fourth quarter stormy weather was of greater significance than the lack of bait in retarding the inshore fishery. The 1962 season will be noted for the successful fishing off the Labrador coast particularly during the last week of July and the middle of August. Some 31 schooners and longliners took part in the Labrador floater fishery and practically all of them reported good results. By way of com- parison 18 vessels prosecuted the Labrador fishery in 1961 while in 1960 there were only 7 vessels on the coast. Cod landings this season are estimated at 375 million pounds, 15 percent higher than last year but about the same as the seven year average. The aggregate value of first-hand sales of cod is estimated at $11.1 million, the highest since the end of World War II. The fishery was particularly good in the Notre Dame Bay, Trinity Bay and Bonavista Bay areas, while the Southwest coast enjoyed the best winter fishery in many years. Below average landings were made by St. Mary's and Placentia Bay fishermen and results were also disappointing on the southern shore and in a few sections of Conception Bay. On the west coast, the cod fishery was generally about average, with the exception of St. Barbe District where landings showed a ,s414taritial increase. Lib HRYA Dept. of Fisheries of Canada 2 St. John's, Nfld. Salted Codfish Salted fish production was 16 percent higher than the level of the pr-)vious year. The following table shows the estimated salted codfish production compared with that of last year: SALTED CODFISH PRODUCTION (cwts. of 112 lbs.) 1 9 6 2 1 9 6 1 Light Heavy Light Heavy -.2Dry Wet Dry Wet Newfoundland (Island) 192,050 365,093 178,827 316,589 (Labrador) 12,950 186,907 7,950 142,269 205,000 552,000 186,777 458,858 The production of light salted increased by about 10 percent over that of 1961 while heavy salted production was greater by 20 percent. However, on the basis of long-term averages the 1962 production figures do not compare as favourably. In fact, the quantity of cod landings put under salt during the year was 14 percent below the ten year average. The trend towards a re- duced dependence on the salt cod fishery and greater reliance on the production of frozen fish continued in 1962. The pro- portion of cod landings entering salt fish production declined from 84 percent in 1953 to 61 percent in 1962. The following table indicates the reduced proportion of cod landings used for salted production and the changing relationship between light salted and heavy salted production: Percentage Share of Cod Landings Entering Salt Fish Production 1953 - 1962 1953 1954 1955 1956 1957 1958 1959 1960 1961 1962 Total 11,L.L 2.2LL /2,1 2.9 72.3 61.8 6.4 69.5 60.0 60.8 Light 65.1 5d.4 45.61 41.0 77.71 24.3 24.1 25.5 2 Heavy 19.3 19.0 24.9 30.8 31.3 30.7 41.1 45.4 34.5 36.3 Light salted fish, which comprised 77 percent of total production in 1953, accounted for only 40 percent in 1962. On a geographical basis the largest increases over last year were recorded in Notre Dame Bay, Labrador and Conception Bay. Production on the southern shore, in St. Mary's and Placentia Bays was below the level of 1961. That section of the west coast, north of Port au Choix produced more light salted fish than usual. In White Bay on the other hand there was a reduction in both the light and heavy salted cures. Largely because of low production in 1961 and a con- tinued strong market demand there was only a relatively small • carry-over of stocks into the 1962 fishing season. Exports of salted fish are somewhat ahead of those for the same period in 1961. Included in these figures are the increasd shipments of salt bulk to The Canadian Mainland. This strong market demand is applicable particularly to the light salted cure and prices to fishermen were con- siderably higher than in 1961. Frozen Groundfish The estimated production of frozen groundfish this year is 72.5 million pounds, an increase of more than 12 per- cent over 1961 and a record high. As already noted, a higher proportion of cod landings is being utilized in frozen fish production. Almost 58 percent, by weight, of total output was cod while haddock, which was next in importance, comprised over 15 percent. As in previous years, most of the production was in the southern part of the island where plants, supported by offshore landings, operate on a year round basis. However, plants on the east coast, operating for only part of the year and dependent entirely on inshore fishing had a much greater relative increase in production than the south coast plants. There were 25 plants in operation in 1962 compared with 22 in 1961. The following table shows the output of frozen groundfiSh for the past four years: Frozen Groundfish Production by Species 1959 - 1962 (quantities in 1 000 pounds) 1962 A 1961 1960 1959 Cod 41,911 38,331 36,567 39,712 Haddock, Hake, etc. 11,148 11,204 6,791 8,058 Redfish 9,755 6,976 5,213 4,087 Flounder & Greysole 8,296 6,991 8,606 6,368 Halibut 740 431 243 317 Catfish & Pollock 625 473 139 342 72,475 64,406 57,691 58,884 A preliminary Frozen cod production more than doubled from 1953 to 1962. The continuing shift of consumer preference in the di- - rection of frozen foods is a significant factor in this trend. As in previous years the American market took the bulk of the frozen fish production. Some shipmebts to the United Kingdom were made during the latter part of the year. The increased landings at freezing plants resulted from higher prices to fishermen and extended collection facilities. A further increase in the size of the offshore fleet, which is oriented to freezing plant production, may also be said to have contributed sig- nificantly toward the increased output of frozen fish. Lobster The lobster catch of 4.2 million pounds was 5 percent higher than in 1961. Landings were good in Notre Dame Bay while fishermen between Cape Freels and Cape Race found lobsters less plentiful than in former years. Along the south coast landings were also lower than last veer, while on the west coast between Cape St. George and Cape Norman catches were much improved over • •• ■1114. the previous season. The total value of first hand sales of lobsters was 01.47 million, compared with 01.25 million in .1961. Prices early in the season were about the same as in 1961 but these improved and as much as 45 cents per pound was realized by fishermen on the west coast. About 95 percent of the catch was marketed alive. Salmon The salmon fishery was fair and landings amounted to 2.2 million pounds, some 4 percent above last season and 8 percent better than the eight year average. As was the case in 1961 approximately 800,000 pounds of the catch came from Labrador. Prices to fishermen were slightly higher than in 1961. 85% of the catch was marketed in the fresh or frozen state and the remainder was either canned, pickled or smoked. Herring The herring catch is estimated at 14 million pounds, 12.5 percent more than last season. About 37 percent of the landings was used for bait and 63 percent was pickled. Landings were valued at approximately $208,000 compared with q3185,000 last year. Good catches were reported from St. Mary's Bay and Bona- vista Bay. Squid The term "Fishermen's luck" can be aptly applied to the year's squid fishery which produced the lowest harvest since 1952.

Drying of the fish samples for all the pre-treatments at 40 0C to 55 0C occurred in the falling rate period only showing that the predominant mechanism of mass transfer in drying process of catfish is that of internal mass transfer. The drying rate increases with increase in temperature for all the pre-treatment methods and decreases with time. The statistical analysis using a factorial design shows that drying rate was significant at (F; 0.05) but there is no significant difference in the pre-treatment methods as well as the interaction between drying temperature and the pre-treatment. The quality parameters (Protein, crude fat and Ash) measured decreases with increase in the drying temperature for all the samples with the blanched samples having the highest value of % protein of 55.94 at 45 0C.

In order to achieve this objective, the collected fresh fish were dried using traditional (without any pre-treatment), improved (fish soaked in a 5% salt solution for 10 min and then treated with chili powder (0.3%) and turmeric powder (0.3%)), and solar tunnel (fish soaked in a 5% salt solution for 10 min) drying methods. The results showed that the dried fish produced by the solar tunnel drying method were rehydrated more rapidly than the products produced by the traditional and improved drying methods. The moisture content of the dried H. molitrix was varied from 18.24 to 25.43% on a fresh matter basis. There was no significant (p > 0.05) difference found regarding the protein, lipid, and ash content among the different drying methods on a dry matter basis.

  • Salting Fish
    Salting Fish Salt can be an important method of preserving smoked fish and controlling bacteria that are capable of causing food borne illness. However, the use of salt in fish to impart desirable flavours often varies according to taste preferences and generally over the years has changed to a lighter salting. The use of heat or smoke during processing, and subsequent storage at refrigerated temperatures are not always effective by themselves in the control of micro-organisms. Why is Salt Content Important? The combination of refrigeration temperatures and prescribed salt levels offer a high degree of assurance that bacterial growth will be retarded. High salt concentrations result in the osmotic transfer of water out of, and salt transfer into, the fish. The removal of water appears to limit bacterial growth and enzyme activity. Due to the concern for botulism, smoked fish that is cryovacked or wrapped to exclude air must be frozen Note: The following formula can be used to compute unless certain conditions are met. For room temperature percent moisture: storage, the product should be sterilized (canned or WeightLoss retorted) and be processed after sealing for a %Moisture = X100 temperature and time to destroy all spores of Clostridium WeightofFishAfterDrying botulinum.

A survey of the quality of salt cured fish in Kanyakumari District, Madras State was done during the years 1963 and 1964 to obtain necessary basic information to formulate quality standards for these products which are gaining importance in the export trade. 155 trade samples of sun-dried, dry-salted, wet-cured and pit-cured fishery products were examined for their chemical quality and organoleptic characteristics. 26.5% of the sun-dried products, 25% of the wet­ cured fish, 55.21% of the dried salted products and none of the pit­ cured samples were found to be good in quality. The sun dried pro~ ducts were generally found to have heavy admixture of sand and were inadequately dried. The chief defects in the salt cured fish products were found to be the use of spoiled fish, imperfect cleaning and washing, use of impure salt, inadequate salting, curing and drying, and unhygienic conditions in all stages. Quality standards must be formulated for each variety of salt cured fish product and adequate measures taken to rectify the defects and enforce the quality standards.

  • Traditionally Preserved Fish Products Are Largely Confined to East And
    Traditionally preserved fish products are largely confined to east and south-east Asia which are still produced principally on a cottage i,ndustry or domestic scale (Adams, 1998). As commonly applied, the term 'fermented fish' covers two categories of product (Adams et a/., 1985): (i) fish-salt formulations, e.g. fish sauce products such as the fish ' . pastes and sauces tend to contain relatively high levels of salt, typically in the range 15-25% and are used mainly as a condiment; and (ii) fish­ salt-carbohydrate mixtures, e.g. pla-ra in Thailand and burong-isda in the Philippines. In hot countries, particulady in rural areas, fermented fish products continue to play a vital role in adding protein, flavour and varietY to rice-based diets (Campbell-Platt, 1987). Table (A) summarises some of the corrimon traditionally processed fish ,~Jroducts of Asia. Among the fermented fish products, the more widely used are fish sauces and pastes (van Veen, 1965; Orejana, 1983). In the fish-salt­ carbohydrate product, lactic fermentation occurs and contributes to the ex.tended shelf life (Adams et a/., 1985; Owens and Mendoza, 1985). Lactic acid fermented products can be prepared in a shorter time than the fish-salt products, which depend primarily on autolytic processes I , and offer greater scope for low-cost fish preservation in South East Asia than the simply, low water activity products (Adams et a/., 1985). The pri~cipal carbohydrate source used in these traditional lactic fermented products is cooked rice, although in some products partially s~ccharified rice (mouldy rice: ang-kak, or pre-fermented rice) is used or, on occasion, sniall amounts of cassava flour, or cooked millet, e.g; sikhae in Korea (Lee, 1984).

  • Fish Processing Sustainability and New Opportunities (Edited by George M
    The following contents are selected from Fish Processing Sustainability and New Opportunities (Edited by George M. Hall); all copyrights belong to Wiley-Blackwell ________________________________________________________________________ Fish Processing Sustainability and New Opportunities 7 Sustainability of Fermented Fish Products S. Kose and George M. Hall 7.1 INTRODUCTION Fermented fish is a broad term for different kinds of fish products. Traditionally, preservation of fresh fish was by salting, smoking and sun-drying (see Chapter 3). Salting and drying in a tropical climate can be prolonged due to high humidity and frequent rainfall, which allows fermentation to start, and people gradually acquired a liking for the taste and the aroma of fermented fish. Another attraction of fermented fish was as a cheap process for underdeveloped countries as an alternative to heavily salted fish products. The ability of fermentation to enhance the flavour (or to mask the taste of tainted fish products) increased its production and consumption even in developed countries (Saisithi, 1994). Today, the demand for fermented food is so great that more varieties are sought. By partially supplementing ordinary salted fish with carbohydrate sources, such as palm sugar, roasted rice or cooked rice, traditional fermented fish products with different tastes and aromas are obtained. Nowadays, non-traditional fermented fish products are also produced using bacterial starter cultures. Fermented fish is generally seen as a South-East Asian product through prime examples such as fish sauce. However, studies showed that such products are commonly found in other parts of the world, especially in Africa. Fermented fish production and consumption are also reported to occur in European countries such as Denmark, Norway and Sweden.
