ACS Monterey Bay Program for September 2009
Fishes And Their Living Habitat: How The "Garden" Grows
|
Understanding the age and growth of fishes and the living habitat in which
they reside is an important part of forming effective fisheries management
strategies. Under-estimation of longevity has played a significant role
in the collapse of major commercial fisheries and it is increasingly common
to find that deep-water fishes and corals are long-lived. Thus, accurate
age estimates are essential to understand the life histories of exploited
organisms and the habitats in which they live.
Our speaker works in the Age and Longevity Research Laboratory at Moss
Landing Marine Laboratories. His research focuses on determining the age,
growth rates and longevity of marine organisms. Methods include analysis
of the patterns and the effects of naturally occurring and man-made radioactivity.
Since 1992 Allen has been working on this research with fishes and more
recently, deep-sea corals. This work has taken him to sites such as the
Farallon Islands, Southeastern Alaska, New Zealand and the Davidson Sea
Mount, right off the Big Sur coast of Central California.
Please join us to learn about these exciting new insights into age and
growth estimation and to enjoy revealing photographic imagery of infrequently
seen deep-water fishes and corals.
