48. The Report of the Symposium has been published as EIFAC Technical Paper No. 39. It has been widely distributed to all EIFAC correspondents and to other interested persons in answer to their request.
49. The Proceedings of the Symposium, edited by Professor K. Tiews, have been published on a commercial basis in the Federal Republic of Germany.
50. The ad hoc correspondence group on “Terminology, Format and Units of Measurement” related to flow-through systems and to recirculation systems has been activated (see paragraphs 51–53) following Recommendation 80/10.
51. An ad hoc correspondence group has been activated in 1981 to propose terminology, format and units of measurement related to the above systems (see paragraph 50), under the leadership of Mr R. Mayo (USA). A first draft has been circulated to members of the correspondence group who have provided comments.
52. Following the resignation in early 1982 of Mr R. Mayo, the work of the correspondence group could not be completed. It has been proposed during the meeting to appoint Dr Rosenthal (Federal Republic of Germany) as the new Convenor. Such proposal has been endorsed by the Commission.
53. It has been mentioned that a meeting of the members of the group would have to take place in early 1983 at the latest, to enable further substantial progress. It has also been suggested that Dr Huisman (The Netherlands) and Dr Muir (UK) become members of the correspondence group.
54. The Fish Diseases COPRAQ continued its activities within the lines of the programme approved by the eleventh session of EIFAC (1980). The fourth session of COPRAQ was held in Cadiz, Spain, in October 1981 (document EIFAC/XII/82/11). The Commission approved its report and noted that the proceedings will be published before the end of 1982.
55. It was agreed by the Commission that the recommendation proposed at this fourth session should be implemented viz. that the work on fish diseases within EIFAC be directed toward workshop-type activities, the planned workshop on prophylactic measures in fish culture being the first of such events (see paragraph 58 of the COPRAQ meeting).
56. Following Recommendation 80/15, a Workshop on Prophylactic Measures in Fish Culture is being tentatively organized in Israel for late August 1982. However, the reaction of possible participants so far has been rather poor, mainly due to financial constraints. It was therefore agreed that the proposed participants who have not yet positively replied to the invitation will be immediately contacted by cable, being given one week for a definite answer. If the total attendance does not reach at least 12, the Chairman of Sub-Commission II will study some other possibilities of organizing such a workshop, for example, combining its venue with the Symposium on Tilapia to be organized also in Israel in May 1983.
57. Following Recommendation 80/17 proposing that investigations in EIFAC member countries be aimed at developing quality control methods to assess the quality of fry/fingerlings for aquaculture and/or restocking purposes, the Sub-Commission discussed the best ways and means of tackling this difficult problem. It recommended (Recommendation EIFAC 82/2) that, based on the wide experience gained in Norway and in Ireland, draft guidelines be prepared in these countries on the assessment of the quality of salmonid fry and fingerlings. These guidelines will then be sent through the Secretariat and the Chairman of Sub-Commission II to the EIFAC correspondents for comments. On the basis of these comments, final guidelines will be tentatively prepared.
58. For the preparation of the above guidelines, the collaboration of ICES and of the North American agencies specialized in this field will be sought. The draft guidelines will be sent to them for comments.
59. The Workshop on the Mass Production of Warmwater Fish Eggs and Larvae was held in Szazhalombatta, Hungary, in June 1980. The report of this Workshop (document EIFAC/XII/82/13) was adopted by the Commission.
60. During the ensuing discussion, it was unanimously agreed that such practical workshops were most useful and that such other meetings should be organized in the future.
61. The Workshop also recommended that EIFAC member countries standardize in the future the terminology to be used in aquaculture documents. It was noted that EIFAC had already in the past contributed to such standardization by producing a “Glossary of Inland Fishery Terms” (EIFAC Occasional Paper No. 12, 1978) and the “Report of the EIFAC, IUNS and ICES Working Group on the Standardization of Methodology in Fish Nutrition Research” (EIFAC Technical Paper No. 36, 1980). Member countries have also prepared glossaries at the national level, and even sometimes in a multilingual form. It was therefore recommended (Recommendation EIFAC 82/3) that copies of existing glossaries of member countries should be provided to the Secretariat who will endeavour to update the present EIFAC glossary. The latter will be finalized only after the publication of the report of the Ad hoc Correspondence Group on Terminology, Format and Units of Measurement related to Flowthrough Systems and to Recirculation Systems (see paragraphs 51–53).
62. After discussion of the possibilities of holding a workshop on the economics of small-scale aquaculture, it was decided that Dr J. Muir (UK) should inform the EIFAC Secretariat as well as the Chairman of Sub-Commission II whether the University of Stirling will be able to host such a workshop as well as to finance such an EIFAC action. In the event that funds have to be raised, it was agreed to try to do this within the Netherlands or to hold the workshop simultaneously with the thirteenth session of EIFAC in 1984.
63. Considering the present status of the work on crayfish and eel within Sub-Commission I, it was decided that Sub-Commission II incorporate in its field of interest aquacultural aspects of crayfish as well as eel, the latter species being given a high priority by some delegates.
64. Sub-Commission II gratefully acknowledged the efforts of the Workshop Chairman, Dr J.S. Alabaster, and the participants in this Workshop, and referred to the report of the Workshop, already widely circulated to the EIFAC National Correspondents and according to the EIFAC mailing list as EIFAC Technical Paper No. 41.
65. The development of low pollution diets received high priority during the subsequent discussion.
66. After extensive discussion of the draft questionnaire circulated, it was decided that:
an improved document will be sent by the EIFAC Secretariat to the EIFAC correspondents in the different member countries, and
the replies received will act as guidelines to rank priorities for future actions to be taken by Sub-Commission II.
67. During the session of Sub-Commission II, the documents EIFAC/XII/82/9, EIFAC/XII/82/11 and EIFAC/XII/82/13 were adopted and tribute was paid to those who contributed to their preparation.
68. With respect to this point of the agenda, two items were raised:
(a) Prevention and control of bird predation in aquaculture and fisheries operations
69. This point raised by the delegation of the Netherlands appeared to be of considerable interest to many delegations. It was decided to take the following action:
A questionnaire on the direct and indirect economical impact of bird predation both in different types of aquacultural enterprises, as well as in open-water fisheries, will be prepared by Dr C.M. Bungenberg de Jong (The Netherlands) and the Chairman of Sub-Commission II. This questionnaire will be circulated by the EIFAC Secretariat.
A working party was established to prepare a document based on literature and experimental data concerning bird damage in:
pond fish culture,
trout culture, and
open waters
taking into account related aspects of fish diseases. Dr Bungenberg de Jong agreed to convene this working group. Dr Molnar (Hungary) as well as two other working group members, to be appointed respectively by the delegations of Denmark and France, will assist in the preparation of such a manuscript.
The above-mentioned documents (the replies to the questionnaire and the working group document, respectively) will be combined by the Secretariat to be handed over to the Director-General of FAO for further appropriate action.
(b) Fish transportation
70. After paying attention to the different problems related to transportation of fish, Dr R. Berka (Czechoslovakia) volunteered to prepare a review of literature on the topic of fish transportation, which was gratefully welcomed by the session.
71. The following persons were proposed for election:
E.A. Huisman (The Netherlands) as Chairman
B. Holmberg (Sweden) as Vice-Chairman
R. Berka (Czechoslovakia) as Rapporteur
72. The delegations agreed upon these proposals and expressed their sincere gratitude to the officers of Sub-Commission II who have served in the past few years, and in particular to the Chairman, Prof. Dr N. Fijan, for his stimulating work.
