New findings in marine ecology described by K. Skajaa and co-researchers
February 25th, 2008
According to a study from Norway, "The escape response of Atlantic cod larvae (Gadus morhua) 25 and 47 days post hatch (dph) - either fed or deprived of food for three days - was studied. Larval escape responses were provoked by water movement from the suction of a fixed-position pipette."
"Escape latency, distance, speed, burst speed, and vertical and lateral escape angles were quantified using motion tracking software designed for 3-D silhouette video recordings. Escape performance, expressed as escape distance and escape speed, improved with age. The escape angles were normally distributed and highly variable, ranging from - 170 degrees to 170 degrees and -40 degrees to...
