The Great Lakes Charter Fishing Industry: 2002 to 2011

We compare results of Great Lakes charter captain surveys from 2002 and 2011. Charter trips declined 27%, from over 103,000 in 2002 to less than 76,000 in 2011. Revenues between the two years fell 24%, from US$48.0 million to $36.4 million, after values were adjusted for inflation. An estimated 1,696 captains operated as a small... Read More

Factors Influencing Charter Fishing Effort Trends in Lake Huron

From 2002 to 2011, the number of charter fishing trips in Michigan waters of Lake Huron declined by 51%. Declines in catch rates, rising gasoline prices, and the economic downturn have been suggested as possible reasons for this decline. To better understand the relative importance of these factors, five catch-based and six economic variables were... Read More

The North Carolina Charter Boat Fishery Changing With the Times: a Comparative Analysis of the Catch Composition (1978 and 2007-2008)

The North Carolina charter boat fishery was surveyed in 1978  and provided a comprehensive assessment of the species catch composition and economic impacts. This fishery was surveyed again in 2007–2008 to provide a more recent representation of the effects and impacts on tourism and coastal fish populations. We analyzed and compared the species catch composition,... Read More

Reservoir Rehabilitations: Seeking the Fountain of Youth

Aging of reservoirs alters the functions, and associated services, of these systems through time. The goal of habitat rehabilitation is often to alter the trajectory of the aging process such that the duration of the desired state is prolonged. There are two important characteristics in alteration of the trajectory—the amplitude relative to current state and... Read More

Functional Age as an Indicator of Reservoir Senescence

It has been conjectured that reservoirs differ in the rate at which they manifest senescence, but no attempt has been made to find an indicator of senescence that performs better than chronological age. We assembled an indicator of functional age by creating a multimetric scale consisting of 10 metrics descriptive of reservoir environments that were... Read More

Development of Fish Passage in China

China began to develop fish passage at hydroelectric dams in the 1960s, but few were implemented until the 2000s, when a federal law was passed in 2002 that required fish passage at new hydroelectric dams that block fish migrations. Because of this regulation, in the past 10 years, about 40 fish passage facilities have been... Read More
