“…Early electronic tagging studies did not fit the two-stock picture. Lutcavage et al (1999), using satellite pop-up tags, observed large adult bluefin tuna in the central Atlantic when they were supposed to be spawning. This suggested mis-specified reproductive schedules (aka skipped spawning; Secor 2008) or perhaps, a third spawning area (Lutcavage et al 1999).…”

This suggested mis-specified reproductive schedules (aka skipped spawning; Secor 2008) or perhaps, a third spawning area (Lutcavage et al 1999). These results generated substantial controversy because they conflicted with other archival tagging results, which showed expected movements of adults to Gulf of Mexico or Mediterranean spawning areas (Block et al 2005).…”

“…This could not be achieved without the detailed observation of free-ranging organisms, which is now possible through the electronic tagging of individuals (Block 2005). In the last few years, this biologging approach has been widely used for various marine species, greatly enhancing our knowledge of physiology, habitat use and movements of long-distance migrants (McConnell et al 1992;Bost et al 1997;Lutcavage et al 1999;Costa & Sinervo 2004;Block et al 2005). Biologging also provides us with unique observations, which are helpful in developing effective marine ecosystem conservation measures.…”

Marine animal behaviour: neglecting ocean currents can lead us up the wrong track

et al. 2006

Tracks of marine animals in the wild, now increasingly acquired by electronic tagging of individuals, are of prime interest not only to identify habitats and high-risk areas, but also to gain detailed information about the behaviour of these animals. Using recent satellite-derived current estimates and leatherback turtle (Dermochelys coriacea) tracking data, we demonstrate that oceanic currents, usually neglected when analysing tracking data, can substantially distort the observed trajectories. Consequently, this will affect several important results deduced from the analysis of tracking data, such as the evaluation of the orientation skills and the energy budget of animals or the identification of foraging areas. We conclude that currents should be systematically taken into account to ensure the unbiased interpretation of tracking data, which now play a major role in marine conservation biology.

“…For small fishes, coded wire tags or fluorochrome tags could be used to tag large numbers of juveniles at low cost (Nielsen 1992;Okamoto 1999;Catalano et al 2001). For large fishes, radio telemetry, ultrsonic telemetry, or satellite telemetry tags have been used successfully (Lutcavage et al 1999;Zhu 2002;Zhang et al 2003). While these technologies exist throughout the world, they have seldom been used in China.…”

Enhancement and conservation of inland fisheries resources in China

The inland aquatic ecosystem in China have been largely influenced by large-scale economic activities and over-exploitation of aquatic resources. Fisheries resource enhancement and conservation activities have been carried out throughout China. These activities include establishing artificial fish habitat and hatchery, releasing juvenile fish to rivers and lakes, forbidding illegal fishing, and setting up natural reserves. The purpose of these activities is to restore the quantity of inland fisheries resources, guarantee sustainable development of fisheries, maintain biological diversity and keep an ecological balance. These activities, conducted with a variety of methods, numerous species, extensive water areas and large scale programs have played an active role in fisheries resource enhancement and conservation. As a consequence the inland water environment has been improved; the biological diversity and fish catch increased, and the social, ecological and economic benefits have been significantly improved. However, problems such as inappropriate technology and nonstandard operations continue to affect fisheries resource enhancement, conservation and ecological stability. This paper reviews the history and practice of inland fisheries resource enhancement and conservation in China, analyzes the existing problems and deficiencies in the activities, and finally make some recommendations on technology and procedures to sustain inland fisheries resources.
