A ONE-YEAR COLLECTION OF LONG-RANGE ECHO RECORDS OF FISH BEHAVIOR
1964
Weston, D. E. | Revie, J. | Wearden, G.
Echo-ranging records have been obtained at Perranporth over a period of about one year, some being continuous over several days. Broadly speaking there are three types of trace, all of them at least partly biological in origin: wrigglers, fixed bottom echoes and diffuse patterns. Fish behaviour is displayed continuously out to 40 miles, and is especially complex near dawn and dusk.
