Larval Baltic herring exposed to low-ration food supply display reduced growth despite subsequent exposure to high-ration food supply. This reduced growth corresponds with the decreased content of water-soluble protein in the low-high ration group. The continuous high-ration group exhibits a higher survival rate when compared to the low-high ration group.

An enzymatic activity assay using a fluorescence technique and a quantitative method using radioimmunoassay were compared for their ability to measure fish larval trypsin content. The results showed that the two methods give similar results, as trypsin activity is correlated with trypsin quantity. The differences between the two methods are discussed and their potential use in the assessment of nutritional status of larval fish for fisheries purposes are examined.

Ten previously described PCR primer pairs were tested on 51 sweet and sour cherry accessions to determine if the primers could differentiate between accessions. The SSR fragment scores were high, with only a few null loci observed for all primer/accession combinations. The loci were highly polymorphic, with 14 – 40 different alleles found at each locus. Heterozygosity values ranged from 0.52 – 1.00, gene diversity (PIC) values ranged from 0.905 – 0.966, and the discriminating power of each locus varied from 0.896 – 0.965 for the sour cherry accessions, from 0.48 – 0.967 for the sweet cherry genotypes, and from 0.803 – 0.921 for the cherry rootstocks. The combined discriminating power of all loci was effectively 1.0. Two accessions shared the same DNA-profile, the sour cherry cultivar ‘Zigeuner Kirschen’ (accession no. DKPcC429) and the cherry rootstock ‘Weiroot 13’ (accession no. DKPcR49). These genotypes are considered to be identical. In this investigation, however, it was not possible to achieve identical DNA-fingerprints for seven sour cherry accessions held at the Danish Research Centre compared to cultivars with the same names from the collection at the U.S. Department of Agriculture, Agricultural Research Service Geneva, NY.
