Research to improve management of Atlantic menhaden in Chesapeake Bay (Page 1)

Research to improve management of Atlantic menhaden in Chesapeake Bay

Ben Longstaff, Caroline Donovan, Emily Nauman ·
21 October 2008

From both an economic and ecological standpoint, Atlantic menhaden are one of the most important fish species in Chesapeake Bay. Concerns over localized depletion and a need for improved understanding of the ecological role of menhaden in Chesapeake Bay led the Atlantic States Marine Fisheries Commission to identify research needed to improve menhaden fisheries management. This newsletter provides the status of some of the resulting projects.

2007 Patuxent River Report Card (Page 1)

2007 Patuxent River Report Card

Ben Longstaff, Caroline Donovan ·
21 April 2008

This newsletter introduces the first Patuxent River ecosystem health report card. This report card provides grades for three regions within the Patuxent River estuary (i.e., the tidal portion of the river). The report card grades are based on the progress of six indicators towards ecological targets. The report card shows that the Patuxent River estuary is mostly in poor condition and that substantially more effort is needed to see measurable improvements.

2007 Chester River Report Card

Ben Longstaff, Caroline Donovan ·
10 April 2008

This newsletter introduces the first Chester River ecosystem health report card. This report card summarizes the 2007 water quality of two major parts of the Chester River ecosystem: the estuary (tidal regions) and the creeks (non-tidal) flowing into the estuary. Creek water quality is based on data collected by the Chester River Association and their Chester Tester volunteers. Health of the estuarine regions is based on data collected by the Chesapeake Bay Program partners.

Chesapeake Bay Health Report Card: 2007 (Page 1)

Chesapeake Bay Health Report Card: 2007

Ben Longstaff, Caroline Donovan ·
3 April 2008

This report card provides a transparent, timely, and geographically detailed annual assessment of 2007 Chesapeake Bay habitat health. This is the second year that the report card has been released. This report card rates 15 reporting regions of the Bay using six indicators that are combined into a single overarching index of habitat health. Habitat health is defined as progress of the six indicators towards established scientifically derived ecological thresholds or goals.

Effects of nutrient enrichment in the nation's estuaries: A decade of change

Bricker SB, Longstaff BJ, Dennison WC, Jones AB, Boicourt KE, Wicks EC, and Woerner J ·
2008

An updated assessment of nutrient related impacts in US estuaries was completed in 2007. This assessment evaluates three components for each estuary: the influencing factors (e.g. land use, nutrient loads), the overall eutrophic condition (e.g. chlorophyll a, presence of nuisance/toxic algae and macroalgae, extent of dissolved oxygen problems, loss of submerged aquatic vegetation), and future outlook.

A summer of poor water clarity, algal blooms, and fish kills (Page 1)

A summer of poor water clarity, algal blooms, and fish kills

Ben Longstaff, Emily Nauman, Caroline Donovan, Bill Dennison, David Jasinski ·
28 November 2007

This year's drought led to lower than normal nutrient and sediment discharge into the Bay during the summer. With fewer sediments and nutrients entering the Bay, the health of the Bay may have been expected to improve, however, this was not the case for water clarity, harmful algal blooms, and fish kills. While dissolved oxygen in the mainstem was still poor this summer, the volume of oxygen depleted water was relatively small compared to the past 22 years.

Incorporating habitat into ecosystem-based fisheries management: Habitat matters! (Page 1)

Incorporating habitat into ecosystem-based fisheries management: Habitat matters!

Wicks EC, Boicourt K, Longstaff BJ and Townsend H ·
16 November 2007

Habitat consists of the physical, chemical, and biological components that are necessary for the survival and growth of organisms in an ecosystem. In an estuary, habitat provides food and shelter for invertebrates, shellfish, and fish. Habitat is an integral part of an ecosystem, and assessing habitats is important in determining ecosystem health.

Asian oysters: Science to inform policy decisions (Page 1)

Asian oysters: Science to inform policy decisions

O'Herron M, King J, Wicks EC, Bushek D and Carnegie R ·
2 November 2007

This is a three part series on the Asian oyster Environmental Impact Statement. It has been proposed to introduce the Asian oyster (Crassostrea ariakensis) into Chesapeake Bay as one potential solution to the loss of the historic oyster fishery, and the ecological functions that oysters perform for Chesapeake Bay.

Effects of nutrient enrichment in the Nation's estuaries: A decade of change

Bricker S, Longstaff BJ, Dennison WC, Jones AB, Boicourt K, Wicks EC and Woerner JL ·
31 July 2007

This report provides an assessment of eutrophic conditions for 141 U.S. estuaries. The report was based on data and information provided by scientists and experts from around the country. Results from the assessment show that two-thirds of the estuaries evaluated exhibited moderate to high levels of eutrophication. Report production was a collaborative effort between Suzanne Bricker (NOAA NCCOS), EcoCheck (NOAA-UMCES Partnership) and IAN. More information is available from the NEEA website.
