Western Rock Lobster Management - Options And Issues, Kevin Donohue Jun 1998

Western Rock Lobster Management - Options And Issues, Kevin Donohue

Fisheries management papers

Following the Rock Lobster Industry Advisory Committee meeting of the 3 March 1998 the Minister has advised that his position is that there will be no management changes for the 1998/99 season. The purpose of this paper is primarily to provide information explaining management options and issues for consideration of the long term management of the fishery. The paper is divided into three main sections which detail options that have been identified as having the potential to increase the catch value over the next three years. In the first section, an option for enhancing the catch value by transferring lobsters …

Ecology And Natural History Of The Cow Knob Salamander, Plethodon Punctatus Highton, In West Virginia, Robert B. Tucker Jan 1998

Ecology And Natural History Of The Cow Knob Salamander, Plethodon Punctatus Highton, In West Virginia, Robert B. Tucker

Theses, Dissertations and Capstones

Very little has been written on the ecology and natural history of the Cow Knob salamander, Plethodon punctatus Highton, since it was described by Highton (1971). Plethodon punctatus is known only from the higher elevations of Great North (above 2,800 ft) and Shenandoah (above 3,000 ft.) Mountains in Virginia and West Virginia (Highton, 1972; Conant and Collins, 1991). The type locality is Cow Knob, Pendleton County, West Virginia. Plethodon punctatus is a large (up to 75 mm snout-to-vent length) dorso-ventrally flattened salamander with creamish iridiophore spots on the back and sides, webbed feet for a fossorial lifestyle, and large …


Life History, Ecology, And Low Ph Tolerance Of The Freshwater Prawn, Palaemonetes Kadiakensis Rathbun, In A Mitigated Wetland Of The Green Bottom Wildlife Management Area, West Virginia, Jennifer Ann Aderman Jan 1998

Life History, Ecology, And Low Ph Tolerance Of The Freshwater Prawn, Palaemonetes Kadiakensis Rathbun, In A Mitigated Wetland Of The Green Bottom Wildlife Management Area, West Virginia, Jennifer Ann Aderman

Theses, Dissertations and Capstones

An ecological life history study of the freshwater prawn Palaemonetes kadiakensis was conducted at the mitigated wetland of the Green Bottom Wildlife management Area (GBWMA). Monthly samples were collected from November 1996 through November 1997. In addition, weekly samples were collected from May through November for growth and reproductive analysis. Monthly samples yielded 520 prawns. Palaemonetes kadiakensis had a one-year life cycle, with all adults dying by September. Males averaged 23.82 mm (range = 14.15 to 36.75 mm) and females averaged 26.78mm (range = 15.06 to 38.60 mm) in length. Males averaged 0.087g (range = 0.014to 0.293 g) and females …


Chondrocranial Anatomy And Skeletogenesis In Dendrobates Auratus, Rafael O. De Sá, Shannon Hill Jan 1998

Chondrocranial Anatomy And Skeletogenesis In Dendrobates Auratus, Rafael O. De Sá, Shannon Hill

Biology Faculty Publications

The larval chondrocranium and visceral skeleton of Dendrobates auratus ls described and compared with those of other dendrobatids. Four characters, i.e. lack of fusion between orbital cartilages and otic capsules, wide processus muscularis palatoquadrati, lack of processus pseudopterygoideus, and lack of processus anterolateralis hyalis, represent derived conditions for Dendrobates within Dendrobatidae. Cranial and postcranial ossification sequences are reported for D. auratus and Epipedobates tricolor. Skeletogenesis is earlier in E. tricolor, but the overall pattern of ossification is similar in the two species.


The Use Of Emergent Rocks As Refugia For The Cheat Mountain Salamander, Plethodon Nettingi Green, Beth Anne Pauley Jan 1998

The Use Of Emergent Rocks As Refugia For The Cheat Mountain Salamander, Plethodon Nettingi Green, Beth Anne Pauley

Theses, Dissertations and Capstones

Plethodon nettinqi was listed as a threatened species in 1989 by the United States Fish and Wildlife Service (Pauley, 1991). Its total range is within 5 counties in eastern West Virginia. There are fewer then 60 disjunct populations known and most populations are above 3,000 ft. and are associated with emergent rocks or narrow ravines with Rhododendron. It is hypothesized the P. netting! survived lumbering practices at the turn of the century by taking refuge beneath large emergent rocks and narrow ravines with Rhododendron. This study examined environmental factors associated with emergent rocks that might regulate the distribution of P. …
