Present Status of Fish Biodiversity and Abundance in Shiba River, Bangladesh
Univ. J. zool. Rajshahi. Univ. Vol. 35, 2016, pp. 7-15 ISSN 1023-6104 http://journals.sfu.ca/bd/index.php/UJZRU © Rajshahi University Zoological Society Present status of fish biodiversity and abundance in Shiba river, Bangladesh D.A. Khanom, T Khatun, M.A.S. Jewel*, M.D. Hossain and M.M. Rahman Department of Fisheries, University of Rajshahi, Rajshahi 6205, Bangladesh Abstract: The study was conducted to investigate the abundance and present status of fish biodiversity in the Shiba river at Tanore Upazila of Rajshahi district, Bangladesh. The study was conducted from November, 2016 to February, 2017. A total of 30 species of fishes were recorded belonging to nine orders, 15 families and 26 genera. Cypriniformes and Siluriformes were the most diversified groups in terms of species. Among 30 species, nine species under the order Cypriniformes, nine species of Siluriformes, five species of Perciformes, two species of Channiformes, two species of Mastacembeliformes, one species of Beloniformes, one species of Clupeiformes, one species of Osteoglossiformes and one species of Decapoda, Crustacea were found. Machrobrachium lamarrei of the family Palaemonidae under Decapoda order was the most dominant species contributing 26.29% of the total catch. In the Shiba river only 6.65% threatened fish species were found, and among them 1.57% were endangered and 4.96% were vulnerable. The mean values of Shannon-Weaver diversity (H), Margalef’s richness (D) and Pielou’s (e) evenness were found as 1.86, 2.22 and 0.74, respectively. Relationship between Shannon-Weaver diversity index (H) and pollution indicates the river as light to moderate polluted. -

MARK-RECAPTURE ASSESSMENT of the RECREATIONAL BLUE CRAB (Callinectes Sapidus) HARVEST in CHESAPEAKE BAY, MARYLAND
ABSTRACT Title of Thesis: MARK-RECAPTURE ASSESSMENT OF THE RECREATIONAL BLUE CRAB (Callinectes sapidus) HARVEST IN CHESAPEAKE BAY, MARYLAND Robert Francis Semmler, Master of Science, 2016 Directed By: Professor, Marjorie Reaka, Marine Estuarine Environmental Science In Maryland, commercial blue crab (Callinectes sapidus) harvests are monitored through mandatory, annual harvest reporting, but no annual monitoring exists for recreational fishers. This study used a large-scale mark-recapture program to assess relative exploitation between the recreational and commercial fishing sectors in 15 harvest reporting areas of Maryland, then incorporated movement information and extrapolated reported commercial harvest data to generate statewide estimates of recreational harvest. Results indicate spatial variation in recreational fishing, with a majority of recreational harvests coming from tributaries of the Western Shore and the Wye and Miles Rivers on the Eastern Shore. Statewide, recreational harvest has remained approximately 8% as large as commercial harvest despite management changes in 2008, and remains a larger proportion (12.8%) of male commercial harvest. In addition, this study provides detailed spatial information on recreational harvest and the first information on rates of exchange of male crabs among harvest reporting areas.

Nick Walker, Ph.D. ([email protected]) Kim De Mutsert, Andy Dolloff, Vivek Prasad, A. Alonso Aguirre Joint Meeting of the American Eel Interest Group and the Sturgeon Interest Group December 12th, 2019 Why eels? Found in more habitats than another fish. Ideal for studies across a wide geographic area. Everyone talks about interconnectedness of ecosystems – eels live it. Connections with humans throughout history, opportunities for citizen science. A fish that can bring people back to nature. Adapted from Tsukamoto (2014). Fig. 1. American Eel sampling events Objectives Objective was to build a model of the subwatersheds of the Chesapeake Bay using a Digital Elevation Model (DEM); then add eel data, dams and land use. Goal was to create color‐coded maps of where eels are doing well and areas that might be prioritized for conservation. This study is follow‐up to our previous work on American Eel demographics in the Chesapeake Bay. Methods –Data collection Eel data from VA DGIF, MD DNR, USFWS et al. Elevation data from ASTER DEM (plus river data from USGS small scale maps). Dam data from The Nature Conservancy. Land use from Université Catholique de Louvain in Belgium. Sources limited by 2019 government shutdown. Methods Delineating streams and watersheds in ArcGIS: Load ASTER tiles (30x30m resolution; 20 tiles for study area). Fill, Flow direction and Flow Accumulation on each tile. Raster calculator: SetNull(“bay_flowac” < 27778,1) This sets minimum threshold to 25 km2 (or 25*106)/(302) Stream Link, Stream Order and Stream to Feature on each tile. Watersheds split along mainstem every 50 km. -
Maryland's Wildland Preservation System “The Best of the Best”
Maryland’s Wildland Preservation System “The“The Best Best ofof thethe Best” Best” What is a Wildland? Natural Resources Article §5‐1201(d): “Wildlands” means limited areas of [State‐owned] land or water which have •Retained their wilderness character, although not necessarily completely natural and undisturbed, or •Have rare or vanishing species of plant or animal life, or • Similar features of interest worthy of preservation for use of present and future residents of the State. •This may include unique ecological, geological, scenic, and contemplative recreational areas on State lands. Why Protect Wildlands? •They are Maryland’s “Last Great Places” •They represent much of the richness & diversity of Maryland’s Natural Heritage •Once lost, they can not be replaced •In using and conserving our State’s natural resources, the one characteristic more essential than any other is foresight What is Permitted? • Activities which are consistent with the protection of the wildland character of the area, such as hiking, canoeing, kayaking, rafting, hunting, fishing, & trapping • Activities necessary to protect the area from fire, animals, insects, disease, & erosion (evaluated on a case‐by case basis) What is Prohibited? Activities which are inconsistent with the protection of the wildland character of the area: permanent roads structures installations commercial enterprises introduction of non‐native wildlife mineral extraction Candidate Wildlands •23 areas •21,890 acres •9 new •13,128 acres •14 expansions Map can be found online at: http://dnr.maryland.gov/land/stewardship/pdfs/wildland_map.pdf -
