Abstract:

The Great Lakes Fishery Commission has traditionally supported the conservation of genetic diversity native to the Great Lakes, and counseled caution in adding new species to the Great Lakes aquatic community. Since extinction of sub-specific taxa and establishment of new species in the Great Lakes have proven irreversible, caution and conservatism are warranted. The Commission's mandate has served the Great Lakes well in preventing, controlling, and managing exotics. For example, the Commission (1) provides a forum for interjurisdictional consultation prior to planned introduction of new fish

Abstract:

Wild populations of the native European flat oyster (Ostrea edulis) are nowadays rare. Worldwide, flat oyster populations have declined due to overexploitation, diseases and pollution. Yet, in the Limfjorden, Denmark, a small but persistent population of wild flat oyster have endured for more than 165 years, which has sustained a unique fishery on wild oyster beds. Over time, fluctuations in the wild population size has had implications for the fishery, alternating between a large population with high yields, and too small to withstand a fishery.

Examples are described in which the invader out-competes native species for the same food, and cases in which the invader consumes valued native species. In many instances, better predator avoidance by the invasive species or the absence of predators in the new habitat contributes to the success of the invaders; in other cases native or introduced predators appear to be able to keep the invasive species in check.

Abstract:

The status of fishery resources of Lake Taal – the third largest lake in the Philippines was assessed to provide updated information on the capture fisheries following the Taal Volcano eruption and COVID-19 pandemic in 2020. Using the methodology of the National Stock Assessment Program of NFRDI, this study was conducted from January to December 2021 at 15 fish landing sites around the lake. In addition, interview schedules of 100 fisherfolk respondents from 11 coastal municipalities were also conducted to assess the effect of the volcanic eruption and pandemic on the livelihood of fisherfolk.

Abstract:

Intensive multi-species fish stocking management is a popular yield enhancement tool that supposedly leads to elevated yields in recreational angling. This study aimed to analyze the relationships between fisheries management of an apex predator and its putative prey. The GAM (generalized additive model) was used to analyze the relationships between the yields and the stocking intensities of European catfish and non-native fish species. The fish yields and stocking intensities were obtained from mandatory angling logbooks collected from 38,000 individual recreational anglers by the Czech Fishi

Abstract:

Accurate age-interpretation techniques were developed, using scales and otoliths, to examine the role of whole-lake neutralization in the resurgence of a lake trout (Salvelinus namaycush) fishery in Nelson Lake (pH 5.7) near Sudbury, Ontario. Calcified structures and data from 860 lake trout were collected from 1972 to 1987. The population was characterized by the regular cyclic occurrence of strong year classes, which were probably an effect of pulse angling, cyclic food abundance, and possibly intraspecific interaction. The majority (65.8%) of the lake trout caught in the exceptional winter

Abstract:

Florida bass (Micropterus salmoides) and largemouth bass (Micropterus nigricans) are iconic sport fish that hybridize readily, influencing fishery management practices. While the Florida bass has been introduced to various U.S. states to create trophy fisheries, its genetic introgression into native populations can lead to ecological and genetic consequences. Recognizing the need to assess Florida bass presence to guide future management directions, diagnostic SNPs were genotyped for 856 putative largemouth bass across 31 sampling locations across the state of West Virginia.

Abstract:

Pacific herring (Clupea harengus pallasi) is a major food source for western Alaska native people and has been commercially exploited in the eastern Bering Sea since the early 1900's. Commercial harvests were small and localized in coastal waters until foreign factory fleets located and developed a fishery on wintering herring concentrations in the early 1960's. Harvests peaked near 150 000 t in the early 1970's and then declined along with catch per unit effort. Foreign harvests were eliminated following establishment of the United States 200 mile Fishery Conservation Zone. In recent years a

Abstract:

Chinook salmon (Oncorhynchus tshawytscha) are widely distributed across the globe, with native stocks in the North Pacific Ocean and self-sustained populations in both the Northern and Southern hemispheres. In their native range, Chinook salmon face many conservation and management challenges, including depleted stocks, loss of genetic diversity, and hatchery influences, whereas naturalized range expansion poses a threat to novel ecosystems. Therefore, ways to improve stock discrimination would be a useful tool for fishery managers. Here, we evaluated otolith shape variation in Chinook salmon

Abstract:

In the late nineteenth century San Francisco Bay hosted one of the American West's most valuable fisheries: Not the bay's native oysters, but Atlantic oysters, shipped across the country by rail and seeded on privately owned tidelands, created private profits and sparked public resistance. Both oyster growers and oyster pirates depended upon a rapidly changing bay ecosystem. Their struggle to possess the bay's productivity revealed the inqualities of ownership in the American West. An unstable nature and shifting perceptions of San Francisco Bay combined to remake the bay into a place to dump

Abstract To inform lake trout (Salvelinus namaycush) fishery management in Lake Huron that has undergone rapid ecosystem changes, we quantified lake trout production dynamics by coupling age-structured stock assessment and fish bioenergetics models. Our approach revealed the connection between piscivore production and prey consumption, included growth compensation to reproduction losses, and allowed comparisons between long-term dynamics of fishery harvests and fish production. We found that, despite the collapse of alewives, a major non-native pelagic prey fish, lake trout production appeared

Abstract:

Recent experiences in the United States suggest that mediators employ a number of techniques designed to resolve disputes over critical technical components of decisions. Some of these techniques, called ‘transformative mediator techniques’, both increase the knowledge base for decisions and enhance the abilities of resource-poor groups to protect and promote their interests. In this paper, elements of transformative and nontransformative mediator techniques are identified and discussed. Examples of mediator techniques are drawn from three cases: A regulatory negotiation to develop emission st
