Abstract
  • A workshop was held in Santa Barbara, California, associated with assessing the populations of nekton animals such as squids, shrimps and fishes. Sessions four major methods of assessing nekton populations: (1) Net collections (2) Acoustics (3) Egg/larval surveys (4) Visual methods, remote sensing and feeding habit studies An attempt was made to review the state of the art for each method including advantages, disadvantages and an evaluation of the accuracy of assessment. In addition, an attempt was made to identify important scientific problems and to recommend areas for future research and development. Some of the major recommendations that were made to improve our ability to quantitatively assess nektonic populations include: 1. Coordinated research programs that utilize complementary combinations of all the above methods, each used in a consistent and repeatable way, to provide better estimates of the composition and abundance of nekton and to enable intercomparisons of the accuracy and precision of sampling techniques. 2. Use of larger nets to sample a broader spectrum of nekton, and development of large, opening-closing trawls. 3. Joint biological-acoustical research to characterize and identify acoustical targets. 4. Development of an advanced acoustical system with multifrequency and deep-towing capabilities.
