This study examines attitudes towards eating fish for dinner in 10-19. year-olds and how these attitudes are affected by a taste experience with different fish and seafood. The main objective is to better understand how taste experiences, good or bad, influence attitudes towards eating fish for dinner. 211 children and teenagers responded to items measuring attitudes on two occasions, before and after a taste experience (i.e. pre-intervention and post-intervention). Data analyses included Wilcoxon Signed Rank Tests to assess the taste experience's impact on attitudes and Kruskal-Wallis Tests to examine differences in attitudes between subgroups (e.g. gender, age groups). It was found that taste experience can contribute to a positive attitude change, and further that there was a significant difference in attitudes between age groups. Early exposures to fish and seafood are suggested to be a promising intervention strategy to increase consumption. Further research into this topic is needed. © 2014 Elsevier Ltd.

The aim of this study was to determine the reliability and accuracy of 3 commercially available handheld lactate meters when measuring hemolymph L-lactate in decapod crustaceans. The instruments tested were Accutrend Plus (AP), Lactate Scout+ (LS), and Lactate Plus (LP), and all models were tested in triplicate and compared with a commonly used enzymatic kit for L-lactate quantification (TB-kit). The Norway lobster Nephrops norwegicus and the European lobster Hommarus gammarus were used as model organisms, with emersion as an invoker of hemolymph L-lactate. Between-method comparisons were investigated by determining correlations (Pearson's r) and concordance (concordance correlation coefficient (CCC) and Bland-Altmand's 95% limit of agreement (95% LOA)) between handheld instruments and TB-kit. Within-instrument variation was tested by calculating the coefficient of variation (CV), and the average absolute deviation from the mean (AD). The within-instrument variation was low for all models (CV, 3.8-6.1%; AD, <0.3 mM), showing high reproducibility of technical replicates. A significant correlation with TB-kit was found for all handheld instruments (AP, r = 0.970; LS, r =; 0.956; LP, r = 0.950). For both AP and LS, there was a moderate and significant concordance with TB-kit (AP, CCC = 0.945; LS, CCC = 0.940). The mean difference from TB-kit was-1.42 mM (95% LOA,-4.50-1.66 mM) for AP and 1.19 mM (95% LOA,-3.13-5.51 mM) for LP. Emersion experiments with the European lobster showed that AP and LS were in line with TB-kit in terms of detecting differences in L-lactate levels between groups of animals. As a result of the high frequency of error readings from LP, this instrument was not considered reliable when measuring L-lactate in decapod crustaceans. In conclusion the handheld instruments AP and LS are found to be reliable instruments when measuring hemolymph L-lactate in decapod crustaceans. Comparison of results from different methods should be avoided, and in cases when accurate absolute measurement of L-lactate is needed, methods allowing for greater accuracy and resolution should be used.

Spawning and nursery grounds are poorly described for the West Nordic stock of Greenland halibut (Reinhardtius hippoglossoides) and the entire stock is assumed to originate from a common spawning ground southwest of Iceland. Greenland halibut with hydrated eggs in their ovary were caught during a gillnet survey in 1995 in Greenland waters. This suggests that the spawning areas for the West Nordic stock are not limited to the previously described area southwest of Iceland. Further this paper provides information on distribution of immature Greenland halibut in the fjords of East Greenland. The densities in Tasilaq area suggest that this area may be part of a nursery area in the West-Nordic management unit. However, the importance of this area to the stock is currently unknown. The results have potential implications for the management of the West Nordic Greenland halibut as the management seems to comprise of several stocks, or perhaps a meta-population. © 2012.
