The received Activity Reports did not cover a key 2026 activity relevant to this resolution - a workshop to assess, prioritize and develop recommendations for ex-situ conservation of freshwater fish globally. This aligns with OP1-3(a-c). The submitted Activity Report from Aquarium Berlin also contributes to OP3d. This leaves OP3e, 4 and 5 currently with no activity to the best of my knowledge.

| Relevant operative para(s) of Res/Rec | Activities Overview | Description | Status | Action |
|---|---|---|---|---|
| 3a, 3c, 3d | Scientific/technical activities | Aquarium Berlin contributes to ex situ conservation of threatened freshwater fishes through successful breeding and management of captive populations in line with IUCN Guidelines on the Use of Ex situ Management. During the reporting period, successful breeding was achieved for six IUCN Red List species: Betta hendra (CR), B. rutilans (CR), B. livida (EN), Parosphromenus anjunganensis (EN), Oreochromis alcalicus (EN) and Tilapia guinasana (CR). | On-going | Full activity report |

Scientific/technical activities
|
In June 2026, a workshop was held to assess, prioritize and develop recommendations for ex-situ conservation of freshwater fish globally. The primary objective of this workshop is to assess and decide whether and which ex-situ management activities should be recommended for a selection of ~360 of the world’s most imperiled freshwater fishes.

Challenges / lessons learned from Activity Reports
| Challenges / lessons learned | Description | Action |
|---|---|---|
| Insufficient / lack of resources | Successful ex situ conservation requires specialised husbandry expertise, suitable facilities and sustained breeding efforts. Maintaining viable captive populations of freshwater fishes can be challenging due to species-specific requirements and the need for long-term population management. |
