Oceanic spawning ecology of freshwater eels in the western North Pacific
The natural reproductive ecology of freshwater eels remained a mystery even after some of their offshore spawning areas were discovered approximately 100 years ago. In this study, we investigate theExpand

Offshore spawning of Conger myriaster in the western North Pacific: evidence for convergent migration strategies of anguilliform eels in the Atlantic and Pacific
The spawning area of the common Japanese conger, Conger myriaster, had remained unknown because spawning adults or its newly hatched larvae were never collected. Using genetic identification, weExpand
