RV Corella Fisheries Laboratory cooperated with the Admiralty Research Laboratory to identify fish detected by long-range sonar equipment installed at the Admiralty Experimental Station, Perranporth. The RV "Corella" was directed from the shore to an area some 65 km distant, that was returning a strong and extended echo. The "Corella" was able to correlate this target with shoals detected on a conventional echo sounder, and substantial catches of sprats were taken in the area using a midwater trawl. The RV "Corella" was used throughout the 1970s for pioneering studies on fish migration. Individual plaice ("Pleuronectes platessa") fitted with 300 kHz acoustic transponding
Madonna with the Fish Madonna with the Fish Madonna of the Fish, known also as Madonna with the Fish is a painting by the High Renaissance master Raphael. Mary sits enthroned with the Jesus on her knee. On one side is St. Jerome kneeling by the Lion; he is holding a book. On the other side the archangel Raphael is presenting at the foot of the throne the young Tobias, whom he formerly guided to the River Tigris, and who bears the miraculous fish whose heart, liver and gall were to restore his father's sight, and drive the demons from his bride.
