Age determination and growth of yellow eels, Anguilla anguilla (L.), from a brackish water, Norway
This paper describes the age determination of European yellow eels from a brackish water area in south‐east Norway. Two different methods were used; clearing in 96% ethanol or burning and cracking. When reading the otoliths twice using the same method, the same age was found in 40% of the readings,...

| Summary: | This paper describes the age determination of European yellow eels from a brackish water area in south‐east Norway. Two different methods were used; clearing in 96% ethanol or burning and cracking. When reading the otoliths twice using the same method, the same age was found in 40% of the readings, a discrepancy of 1 year was found in another 40% of the readings (both methods). Burning and cracking yielded age estimates which were on average 1.25 years higher than those obtained by clearing. |
