Crossroads of the deep

This film records a big game fishing trip in the converging waters of the mineral-rich Ecuadorian and Humboldt currents off the coast of Peru. The proliferous plankton, which lives off of these minerals, provides an attractive feeding ground for large game fish. After boarding their craft, the Don Fredy, at an Indian fishing village, Alfred Glassell Jr. and his crew fight and eventually haul in marlin and broadbill swordfish. Footage of the tuna fishing boats from the Oceanic Co. follows, depicting the use of seines to bring in sizable loads of tuna. Also included in this film are sequences showing shearwaters, pelicans, and distant whales, as well as a fabulous shot of a manta ray, which measures 25 feet across.
