COURSE 2: Estimation of Abundance of Marine Mammals
Location: Industria Lobera y Pesquera del Estado (lLPE), Cabo Polonio, Uruguay
Dates: November 23-December 5, 1987
Coordinators: Drs. Martin Hall (IATTC) and Isaías Ximénez (lLPE)
lnstructors: Lic. Alejandro Anganuzzi, Dr. Stephen Buckland, and Dr. Martin Hall (lATTC), Lic. Ana
Parma (University ofWashington), Dr. Anne York (U.S. NMFS)
Program:
Problems for the conservation and management of marine mammals.
Interaction with man: direct fisheries and incidental take.
Models used to manage marine mammals: maximum sustainable yield and variations,
assumptions, deficiencies, and results of their use.
Monitoring marine mammals as an alternative approach to modelling for management and
conservation.
What is estimation? Bias, precision, absolute and relative abundance, and trends.
Sampling design for marine mammal populations.
Estimation ofvariances: analytical and non-parametric methods.
Methods used to estimate abundance.
Line and strip transects: models and assumptions.
Surveys: shore, aerial, and vessel. Design and comparison.
Counts: practical problems and limitations.
Mark-recapture studies: assumptions, models (closed and open populations).
Catch-per-unit-of-effort methods: Leslie, DeLury, and use of tagging or
photoidentification as ways of "catching."
Change-in-ratio methods: Kelker, Chapman, and Paulik-Robson.
