Available online 20 November 2008 In the United States, hundreds of small hydropower dams will come up for relicensing in the coming decade. Whether or not the licensees are renewed and what happens to the dams if the licenses expires Keywords: is a subject of great debate. Dams are beginning to be removed for river restoration and fisheries Dams Dam removal restoration and these ‘‘end-of-life’’ decisions may offer lessons for countries proposing or currently Hedonic property value analysis building small (and large) hydropower dams. What can these restoration stories tell us? GIS In this paper, we examine the effects of dams along the Penobscot River in Maine (USA) on residential property values. We compare the results to findings from a similar (but ex post dam removal) data set for properties along the Kennebec river in Maine, where the Edwards Dam was removed in 1999. -

B. Quantitative Characters Morphometric & Meristics Laboratory
Lab. No. 2 B. Quantitative Characters Morphometric & Meristics laboratory Taxonomic Characters The first step in successfully working with fishes is correct identification. Similar species require in depth examination to discern the few differentiating characteristics. Many times these examinations require accurate measurements and counts of fin ray elements. Objectives: The purpose of this lab is to introduce students to these characters. Quantitative Characters Quantitative characters are usually expressed as numbers, these include a measurable and countable characters. Morphometrics are measurable characters or length-based measures of specific body parts, such as total length of the body or diameter of the eye. These characters are usually measured in the millimeter scale. Meristics are counts of things which occur more than once, but a variable number of times between species (and sometimes within species). These include counts of fin elements, i.e.: the number of dorsal fin spines and rays. NOTICE Spines are hard, pinlike projections, while rays are soft and brush-like Occasionally, fins will be a mix of both spines and rays; however, spines are ALWAYS the most forward structures (closest to the head) on the fin. The table below helps you to differentiate between a spine and a ray Spines Rays Hard and pointed Segmented Unsegmented Sometimes branched Unbranched Bilateral with left and right halves Solid Because they are already dimensionless, meristic measurements can be compared directly. 8 Lab. No. 2 Laboratory exercise In this exercise we will be making various measurements and counts on several species of fish. Record the appropriate information in the attached table. Procedure—Morphology • Each group is equipped with: • Dissecting microscope • Needle probe • Dissecting tray • Scissors • Petri dish • Scalpel • Calipers • Slides and coverslips • Forceps (fine tip and blunt tip) • Latex gloves (optional) Each team should get a fish. -

The Genetic Basis of Morphometric and Meristic Traits in Rainbow Trout (Oncorhynchus Mykiss)

Understanding the genetic basis of phenotypic variation in body form could lead to breeding strategies aimed at adapting body shape to captive environments. In the present study, QTLs associated with morphometric and meristic traits in rainbow trout were identified using a genetic linkage map created from a cross of two clonal lines divergent for morphology and life history (wild steelhead trout and domesticated rainbow trout). Genome regions associated with differences in morphological (body depth, mouth orientation, caudal peduncle shape, anal and dorsal fin length) and meristic (number of skeletal elements of median and paired fins and of caudal fin) characters were identified. The identification of genomic locations influencing body morphology, even if only at a gross level, could be of pivotal importance to direct breeding strategies in commercial hatcheries towards the production of more desirable body types. -
REVIEW of the ATLANTIC STATES MARINE FISHERIES COMMISSION's INTERSTATE FISHERY MANAGEMENT PLAN for SPINY DOGFISH (Squalus Acanthias)
REVIEW OF THE ATLANTIC STATES MARINE FISHERIES COMMISSION'S INTERSTATE FISHERY MANAGEMENT PLAN FOR SPINY DOGFISH (Squalus acanthias) May 2004 – April 2005 FISHING YEAR Board Approved: February 2006 Prepared by the Spiny Dogfish Plan Review Team: Ruth Christiansen, ASMFC, Chair I. Status of the Fishery Management Plan Date of FMP Approval: November 2002 Date of Addendum I Approval: November 2005 Management Unit: Entire coastwide distribution of the resource from the estuaries eastward to the inshore boundary of the EEZ States With Declared Interest: Maine - Florida Active Boards/Committees: Spiny Dogfish and Coastal Shark Management Board, Advisory Panel, Technical Committee, Stock Assessment Subcommittee, and Plan Review Team In April 1998, the National Marine Fisheries Service (NMFS) declared spiny dogfish overfished. The Mid-Atlantic and New England Fishery Management Councils jointly manage the federal spiny dogfish fishery. NMFS partially approved the federal FMP in September 1999, but implementation did not begin until the May 2000, the start of the 2000-2001 fishing year. The federal FMP uses a target fishing mortality to specify a coastwide commercial quota and splits this quota into two seasonal periods (Period 1: May 1 to October 31 and Period 2: November 1 to April 30). The seasonal periods also have separate possession limits that are specified on an annual basis. In August 2000, ASMFC took emergency action to close state waters to the commercial harvest, landing, and possession of spiny dogfish when federal waters closed because the quota was fully harvested. With the emergency action in place, the Commission had time to develop an interstate FMP, which prevented the undermining of the federal FMP and prevented further overharvest of the coastwide spiny dogfish population. -
