Trout Fishing in Hillsdale July, 2012 Guy Winig, Member Hillsdale Conservation Advisory Council
Roe Jan Brown-released to fight another day. Trout Fishing in Hillsdale July, 2012 Guy Winig, member Hillsdale Conservation Advisory Council Trout are our canaries in a coalmine. They are an excellent indicator of stream health, requiring clean, cold, well-oxygenated water to thrive. Without very high quality surface waters, trout just cannot survive. Hillsdale is fortunate to have several miles of trout streams including the Roeliff Jansen Kill, Taconic Creek, Agawamuck Creek and Green River with numerous smaller and unnamed tributaries contributing to them. Our streams and their residents endure many perils including natural flood and drought cycles as well as man made impacts like pollution, invasive species, barriers and over –fishing. Erosion adds silt that smothers aquatic food sources and gravel spawning beds. Introduced Didymo algae (a.k.a. ‘Rock Snot’) now found in the Green River, also chokes the streambed. Loss of vegetation exposes water to heating and eliminates important breeding, feeding and cover areas for trout. Readers may recall the massive fish kill that resulted from the release of manure into the Roe Jan in the 90’s or tales of unscrupulous ‘sportsmen’ using small explosives and chlorine to kill all the fish in a segment of stream. Maybe the most harmful and insidious are non-point sources of pollution such as chemicals, fertilizers and heated runoff from parking lots, roads, roofs, crop fields and lawns. In 2009 and 2010, members of the community with help from the Columbia-Greene chapter of Trout Unlimited and the N.Y.S.D.E.C. Trees for Tributaries program planted several hundred small trees and shrubs on the banks and flood plain of the Roe Jan Kill through the Roe Jan Park in an effort to stabilize banks, introduce vegetative cover and provide shade to maintain cool stream temperatures. -

Ecosystem Services Generated by Fish Populations
AR-211 Ecological Economics 29 (1999) 253 –268 ANALYSIS Ecosystem services generated by fish populations Cecilia M. Holmlund *, Monica Hammer Natural Resources Management, Department of Systems Ecology, Stockholm University, S-106 91, Stockholm, Sweden Abstract In this paper, we review the role of fish populations in generating ecosystem services based on documented ecological functions and human demands of fish. The ongoing overexploitation of global fish resources concerns our societies, not only in terms of decreasing fish populations important for consumption and recreational activities. Rather, a number of ecosystem services generated by fish populations are also at risk, with consequences for biodiversity, ecosystem functioning, and ultimately human welfare. Examples are provided from marine and freshwater ecosystems, in various parts of the world, and include all life-stages of fish. Ecosystem services are here defined as fundamental services for maintaining ecosystem functioning and resilience, or demand-derived services based on human values. To secure the generation of ecosystem services from fish populations, management approaches need to address the fact that fish are embedded in ecosystems and that substitutions for declining populations and habitat losses, such as fish stocking and nature reserves, rarely replace losses of all services. © 1999 Elsevier Science B.V.

LYLES Gulf Coast Research Laboratory, Ocean Springs, Mississippi 39564 and Gulf States Marine Fisheries Commission, Ocean Springs, Mississippi 39564 ABSTRACT The writers describe various small types of plankton blooms such as those occurring in boat slips, the head of a large bayou and a strip type bloom of Chaeroceras on the Gulf beach. Oyster kills from “poison water” draining off of marshes are said to be caused by plankton bloom. Small “jubilees” are said to be caused by localized blooms and one of these is described as it occurred.

Little Fish, Big Impact: Managing a Crucial Link in Ocean Food Webs
little fish BIG IMPACT Managing a crucial link in ocean food webs A report from the Lenfest Forage Fish Task Force The Lenfest Ocean Program invests in scientific research on the environmental, economic, and social impacts of fishing, fisheries management, and aquaculture. Supported research projects result in peer-reviewed publications in leading scientific journals. The Program works with the scientists to ensure that research results are delivered effectively to decision makers and the public, who can take action based on the findings. The program was established in 2004 by the Lenfest Foundation and is managed by the Pew Charitable Trusts (www.lenfestocean.org, Twitter handle: @LenfestOcean). The Institute for Ocean Conservation Science (IOCS) is part of the Stony Brook University School of Marine and Atmospheric Sciences. It is dedicated to advancing ocean conservation through science. IOCS conducts world-class scientific research that increases knowledge about critical threats to oceans and their inhabitants, provides the foundation for smarter ocean policy, and establishes new frameworks for improved ocean conservation.

Catch and Release Fishing; Effects on Bass Populations
Pennsylvania Fish and Boat Commission Harrisburg PA www.fish.state.pa.us Catch & Release Fishing; Effects on Bass Populations By PFBC Staff Catch-and-release fishing is often seen by the public as an effective way of keeping good-sized largemouth bass and smallmouth bass in a population so that these fish can be caught again. But does it work? That is, how well do bass survive catch and release, and are there things anglers can do to improve the odds? A lot of research has been conducted on this topic. Here we will discuss the facts of catch-and-release mortality and how anglers can help improve bass survival. Catch-and-release fishing has become the norm, instead of the exception. Anglers proudly proclaim they release their catch with bumper stickers, hats and t-shirts. But just because the bass swims away, its survival isn’t guaranteed. Many anglers wonder about bass survival after fishing tourna- ments, and if catch and release works to keep good-sized bass in their local lakes and rivers. Much research on this topic has been done in Pennsylvania and elsewhere. There are many issues that affect if a bass will survive being caught or not. By using the best practices possible, anglers can help bass survive. Mortality Mortality can come about two ways in fish; naturally and through fishing. Natural causes include disease or being eaten by a predator. Fishing mortality can come from either the fish being harvested by an angler or from injuries or stress from catch and release. The mortality rate of a waterway is a measure of how many fish die or are removed over a year. -
Fish Kills in NSW Frequently Asked Questions
Fish Kills in NSW Frequently Asked Questions What is a ‘fish kill’? A fish kill is a sudden and unexpected mass mortality of wild or cultured fish. Fish kills can generate considerable public and media interest and concern as they are often perceived to be the result of water pollution. However there are many causes of fish kills and often they are caused by natural events. How many fish kills occur in NSW each year? The Department of Primary Industries (Fisheries) (DPI) maintains a statewide database of reported fish kills in NSW. It contains almost 1400 records dating back to the early 1970s. A review of the data shows that since 1980 an average of 40 fish kills are reported to DPI each year (see Figure 1 below). Since many smaller kills go unnoticed and others remain unreported, the real number of kills is considered to be larger. However, increasing community awareness and improved reporting arrangements are likely to result in less fish kills going unreported and will also assist DPI to gather more information on the extent and causes of fish kills in NSW. Figure 1 Total Number of Fish Kills recorded for each calendar year from 1980 to 2010 80 70 60 50 40 Total no. of kills Number of kills 30 20 10 0 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 What species of fish are affected? Over 100 species of fish, including finfish, molluscs and crustaceans, have been reported in fish kills in NSW since records began. -
