2. Sea Cucumbers Resource Stock Assessments

3. Sea Cucumbers Stock Assessment Methods
Stock Assessments In Situ
Evaluate current species numbers, size and age
Broad and fine scale activities
All habitats
Manta tows
Line transects
Timed swims
SCUBA transects
Day and Night (burrowing, nocturnal)

4. Sea Cucumbers Stock Assessments
Incorporate abiotic and biotic factors
Habitat (reef slope, lagoons sea grass beds etc), water depth, substrate types, dominate benthic forms (coral, sea grasses, sand, rubble etc), etc
GPS coordinates for start and finish of all activities (to allow duplication)
Length and weight measurements They should include species parameters
Species, morphological (body length, weight), location (GPS), water depth, habitat

5. Assessment Distribution

13. Sea Cucumbers Stock Assessments
Social Data (Numbers of fisherman involved, village names, areas fished etc)
Fishing gear used (snorkeling, SCUBA, dredging)
Catch per unit effort data
Location of fishing grounds
Processing techniques
Reporting species and numbers caught (possible size of individuals
