Thus, sea water temperature was correlated significantly and positively with captures of saithe (C = 0.126, p < 0.01) and mackerel (C = 0.157, p < 0.01), and significantly and negatively correlated with captures of sea trout (C = −0.237, p < 0.01) (Table 5).
Salinity was correlated significantly and negatively with captures of pollack (C = −0.165, p < 0.01) and mackerel (C = −0.125, p < 0.01) (Table 5).
Captures were significantly higher in regularly cleaned traps than in traps without cleaning, and at tree canopy height; however, the latter were positively correlated with captures from traps positioned at breast height.
Captures of saithe and pollack were significantly and negatively related between them (C = −0.155, p < 0.01), while mean daily catches of mackerel were significantly and positively correlated with captures of herring (C = 0.153, p < 0.01) and pollack (C = 0.097, p < 0.05) (Table 5).
Furthermore, mean daily catches of sea trout were correlated significantly and positively with captures of saithe (C = 0.089, p < 0.05) and pollack (C = 0.133, p < 0.01), and significantly and negatively with cod (C = −0.102, p < 0.05) and mackerel (C = −0.110, p < 0.05) (Table 5).
Other variables exhibited discrepancies between their associations with captures and those with sightings.
