Fish Frier Trials with Blue Whiting

This report, prepared by David Elliott and Associates on behalf of the Authority, is reproduced in full as it contains very valuable information on the sale of blue whiting through frier outlets. There is no doubt that blue whiting is acceptable when sold in this manner, and a trade can be developed. The future level of such trade will depend upon the provision of graded fillets, preferably at the larger end of the range tested, and the price at which they can be made available.

Halibut Hatchery Report 1990

The 1990 halibut hatchery season was the most successful so far at Seafish Ardtoe with 128 metamorphosed fish being produced. The reasons for this success after the failure to produce fish in the two previous years were thought to relate to better water quality and a general improvement in the reliability of the systems.

Effluent Sampling at Croan Seafoods

Water use and effluent strength are major problems for the seafood processing industry. In the late 1990’s and early 2000’s, changes in the charging scheme for trade effluent discharge resulted in a significant rise in costs across the whole of the seafood processing industry. This particularly affected the pelagic industry which uses a large volume of water and produces very high strength effluent.

Experimental Fishing Using Fish Traps

The report describes fishing trials undertaken by Seafish under MAFF Commission MF0614. Six Neptune traps were fished over a 10 day period around Flamborough Head. They were set on wrecks and rough ground unsuitable for trawling. Fish catches were generally low, probably because of tidal and similar influences. Lessons learned will be useful in the design of a further scheduled study.

Summary Report into Oyster and Clam Purification Criteria

During the period December 1991 to April 1992 Seafish carried out a series of trials to investigate the purification of native oysters (Ostrea edulis) and three commercial species of clam, hard shell (Mercenaria mercenaria), manila (Tapes philippinarum) and native (Tapes decussatus). Experimental purification tanks were used and relative activity levels at different seawater temperatures and mollusc densities assessed by visual observation, dissolved oxygen depletion, uptake of red dye and bacteriological analysis. The trials indicated that the current minimum seawater temperatures specified for the purification of native oysters and hard shell clams were too low whereas manila clams were active at much lower temperatures. Stacking native oysters four deep and manila and native clams in 130mm layers did not appear to cause any reduction in activity. The scope of the trials was limited as a result of difficulties in obtaining sufficiently polluted shellfish resulting in no positive bacteriological result. However, some recommendations are made. To assist in the approval of purification systems MAFF and Seafish have developed a technique for the artificial dosing of bivalve molluscs with the bacteria Esheria coil, so far used with mussels and pacific oysters. The opportunity was taken to use this technique during some of the trials. Native oysters were dosed satisfactorily but some difficulty was experienced with manila clams and a larger dose and longer immersion time were required.
