Report on the “Assessment of the Population Dynamics of the northeast offshore spotted and the eastern spinner dolphin populat
نویسنده
چکیده
The determination of whether purse seine fishing in the Eastern Tropical Pacific is hampering the recovery of the northeastern offshore spotted dolphin and eastern spinner dolphin populations is a difficult problem. The question was not answered satisfactorily by a simple consideration of population abundance estimates, despite these estimates being made using innovative methods and great care and effort. The three population estimates made in 1998-2000 did not differ statistically from the five estimates made in 1986-1990. In order to determine if recovery were occurring the available data needed to be assessed using a population dynamics model.

Current information is reviewed that provides clues to the intraspecific structure of dolphin species incidently killed in the yellowfin tuna purse-seine fishery of the eastern tropical Pacific (ETP). Current law requires that management efforts are focused on the intraspecific level, attempting to preserve local and presumably locally adapted populations. Four species are reviewed: pantropical...
متن کاملDepletion of spotted and spinner dolphins in the eastern tropical Pacific: modeling hypotheses for their lack of recovery
We assess the status of 2 dolphin stocks affected by purse-seine fishing in the eastern topical Pacific and evaluate hypotheses for their lack of recovery. We use Bayesian methods and fit generalized models of logistic population growth to abundance estimates for northeastern offshore spotted dolphins Stenella attenuata attenuata and eastern spinner dolphins Stenella longirostris orientalis. In...

Cetacean sighting data collected under various programmes in Colombian Pacific waters were collated with the goal of assessing the distribution and abundance patterns of all species occurring in the exclusive economic zone (EEZ). Distribution maps are presented for 19 species and one genus based on 603 sightings collected between 1986 and 2008. Ordered by sighting frequency, these species were:...

متن کاملDolphin Habitats in the Eastern Tropical Pacific
Research-ship surveys by the Southwest Fisheries Center provided information on the distributions of spotted, spinner, striped, and common dolphins in the eastern tropical Pacific. The main surveys were conducted from January to March during 1976,1977,1979, and 1980. 1\\'0 ships were used per survey, and together they overlapped most areas in the eastern Pacific where dolphins and yellowfin tun...
