Data were digitalized into a database from the historic reports.

取樣方法
Large seine nets, fyke nets and drift nets (gill nets) used by commercial fishermen
| 研究範圍 | On the large rivers mainly large seine nets (zegen), fyke nets (zalmsteek) and drift nets (gill nets) were used to catch migratory species. On the Wadden Sea migratory species were mainly a by-catch of other fisheries. |
