Complex Life History

Many reef fishes change sex during their life. The testing of life-history theory and effective fisheries management therefore relies on our ability to detect when this fundamental transition occurs. This study experimentally illustrates the potential to glean such information from the otolithic bodies of the inner-ear apparatus in the sex-changing fish Parapercis cylindrica . It will now be possible to reconstruct the complete, often complex life history of hermaphroditic individuals from hatching through to terminal reproductive status. The validation of sex-change associated otolith growth also illustrates the potential for sex-specific sensory displacement. It is possible that sex-changing fishes alter otolith composition, and thus sensory-range specificity, to optimize life history in accordance with their new reproductive mode.

Legislated marine "protected" areas are now widely distributed throughout tropical and temperate waters, but the nature of human activities actually restricted in any area varies. This ambiguity about what "protected" means has resulted in contradictory claims as to both the benefits and costs of marine protected areas. Here, we give our perspective on the current status of marine resource protection in Canada in general and British Columbia in particular. We first describe and discuss the history of Canadian marine protected areas established to date. Many areas are claimed to be protected, with little understanding by either the general public or even most marine resource experts as to what human activities are actually regulated by legislative designations. Second, we present an overview of biological reasons and objectives for marine protected areas, followed by a review of both the conservation and fisheries management effects and implications resulting from effective renewable resource protection. Finally, we propose a unique qualitative scheme for classifying and describing marine protected areas of different types to determine relative measures of protection.

<em>Abstract.</em>—The red snapper, <em>Lutjanus campechanus</em>, is one of the most economically important fish species in the Gulf of Mexico (GOM). Concerns over the declines in red snapper landings during the 1980s in the GOM exposed the paucity of information regarding the species’ age, growth, and population dynamics, all fundamental in fisheries management. This paper reviews the history of red snapper age and growth research in the GOM demonstrating an evolution of fisheries aging and validation techniques. These refinements in aging over time have also impacted management of the red snapper stock in the GOM. Also discussed are efforts to standardize aging techniques throughout the GOM in an effort to improve data accuracy. A number of studies have used the von Bertalanffy growth model to describe a pattern of rapid growth followed by slower growth after the age of ten years for red snapper in the GOM. Additional applications of the von Bertalanffy growth model have also been applied to corroborate red snapper age estimates derived from sectioned otoliths and to discern demographic differences in red snapper growth throughout the GOM.

AbstractThe SEAFO Convention, signed in April 2001, is one of the first new conventions to create a regional fisheries management organisation since the adoption of the UN Fish Stocks Agreement. The negotiating history of the convention, and the way the SEAFO participants dealt with key issues in the international fisheries management, illustrates effective use of the Agreement, even before the entry into force of the Agreement, and while it remains uncertain whether all SEAFO participants will also be bound by the Agreement when it is in force. The SEAFO Convention also deals with discrete high seas stocks, not covered by the Agreement.

History Of The South

A brief history of the South East Fishery is presented, focussing on the period 1986–2000. With the realization in the 1980s that natural resources are finite, active fisheries management became more of a focus for the Australian Federal Government. This paper describes the Federal Government’s fisheries management objectives since the mid 1980s as well as major new policy initiatives, and seeks to measure the performance of the fishery against key management objectives. A few simple indicators of change are examined with particular reference to the pursuit of economic efficiency.

The vast majority of inland waters in Ontario have been designated as purely recreational fisheries. Environmental historians who study human-fish relations have demonstrated the influence of anglers in the establishment of fishing regulations and fisheries management policies that sought to maximize fish resources for sport fishing and fishing tourism. To achieve this goal, aquaculture programs were conducted throughout Ontario that artificially reared fish and planted them in lakes. For over a century, from approximately 1860-1960, Ontario relied on aquaculture as a blanket solution to all fishery problems. Over the past fifty years, fisheries science has questioned the ecological benefits of stocking programs. Stocking efforts in the province have been drastically reduced since the 1960s but have continued largely because of grass root initiatives from concerned anglers. Lake Ahmic is home to a small cottage community based out of the village of Magnetawan. The lake has been stocked with a variety of fish species for over a hundred years. In addition to this, several species have been accidentally introduced to Lake Ahmic altering its ecological balance. Between 1987 and 2006, a local angling organization was responsible for initiating and running a walleye-stocking program on Lake Ahmic. In 2006, to the disappointment of the local anglers and greater Magnetawan community, the Ontario Ministry of Natural Resources canceled the stocking program. At the root of the discord between the community and the government is a century long history of efforts to engineer a desirable nature at Lake Ahmic, as well as shifting ideas of what this desirable nature is, and the role that science should play in bringing it about. I argue that a century of stocking fish on Lake Ahmic has reified the practice into the community’s conservation ethos. The environmental history of Lake Ahmic adds insight into the social and political tensions that have arisen as a result of the cancelation of the stocking program.

Fisheries provide critical contributions to global food security and are important in the fabric of human societies throughout the world. This chapter provides a brief history of fishery development and the evolution of scientific understanding and approaches so critical to effective fisheries management. It shows how processes at the population, community, and ecosystem levels are manifest in complex ways in even simple descriptors such as catch histories. Although many aspects of conventional fisheries management center on equilibrium concepts, the empirical record suggests a much more complex reality with the possibility of alternate stable states and non-linear dynamics. This chapter provides the motivation for exploring alternative models of fishery dynamics in a broader ecological context. Confronting complexity is essential if we are to move toward operational Ecosystem-based Fishery Management on a global basis.
