Indol, sulfite                             

Importance of tropical species in each country
Several members reported that there are no reliable data available on the importance of tropical species in their countries thus the development of a questionnaire was given up. Exchange of information on tropical species shall be kept on the agenda.
H. Karl informed the participants, that water-binding substances other than phosphates are applied for Pangasius which are more difficult to detect. He will send around more information.

Dioxins in Baltic salmon
M. Timm-Heinich presented the results of a Danish project of the effect of trimming on the dioxin and dl-PCB content in Wild Baltic salmon.

Parasites
The group addressed the problem, that most countries have neither reliable data of the abundance, prevalence and distribution of nematodes in important food fishes neither from local landings nor of their possible variation due to changes of biological parameters.
Most participants showed their interest in this research field.

Results of inter-laboratory trial on fat determination
The results of a preliminary inter-laboratory trial on fat determination applying a modified method according to Smedes were promising and the group decided to run a second trial. The trial shall follow the international standards for inter-laboratory trials. Samples will be prepared and distributed by Germany.
