| Status | Completed |
| Port of departure | Gairloch, United Kingdom |
| Purpose | Fisheries |
| Objectives | Joint cruise with the Heathery Brae
Aims: 1. To investigate the survival rates (in underwater cages) of cod, haddock and whitin escaping from cod-ends of 90x120mm meshes round, 90x100mm meshes round and 90mm with a 80mm square mesh top panel 2. To obtain selectivity data for each cod-end. Narrative: The underwater cages were transported by the scallop dredger Salar to a position on the east side of Longa Island during the first week. Also during this first week haddock, whiting and codling were caught on handline and kept in 3 of the cages as controls. Fish caught by the Heathery Brae which escaped through the cod-end meshes were transported to the cages. Results: Survival percentage after 19 days in the underwater cages: 90x120mm: haddock 42%; whiting 93%; cod 96% 90X100mm: haddock 94%; whiting 82%; cod 100% 90 with 80mm: haddock 76%; whiting 94%; cod 100% After 29 days only 1 more whiting had died. No further deaths during the next 12 days. Fish whos scales started to deteriorate usually died within a few days. |

| Demersal fish | Quantity: activity duration in days = 7 Description: During the 1st week haddock, whiting and codling were caught on handlines and kept in cages as controls for the experiment. |
| Demersal fish | Quantity: number of hauls = 1 Description: Extra hauls had to be made to boost the number of codling needed for the cage experiments. No. of hauls not specified. |
| Demersal fish | Quantity: activity duration in days = 11 Description: Within this period small haddock, whiting and codling were taken. Fish escaping the codend mesh were retained for survival experiments. |
