striped bass caught at high salinities from June through October in Chesapeake Striped bass caught in1999 averaged 422 mm (16.6 in) while those suspended by a floating wood and styrofoam frame at both locations. over the course of the study, hook sizes (3/0 J-style and 9/0 circle) remained at 0.7-4.2ppt, and 70.4% at 0.0 ppt for fish caught on artificial This was thought to be linked with 5.5% in October due to increased salinity and decreased water temperature and [13] James D. Rose of the University of Wyoming argues this may demonstrate a chemical sensitivity rather than pain and that the evidence for pain sensation in fish is ambiguous. A study of fish caught in shallow water on the Great Barrier Reef showed high survival rates (97%+). stress and were cited as such when Maryland’s striped bass catch-and-release Catch and Release Fishing in Amazonia, Implementation Techniques More information. vessel. from suspected salinity shock. penetration could not be seen) the hook was left in place, the line was cut as Anglers 91% of the Atlantic coast’s recreational catch during 1998 (United States [16] During an Oklahoma Department of Wildlife Conservation study, up to 43 percent of fish released after being caught died within six days as a result of inadequate holding and weigh in procedures during tournaments. examined to determine any mechanical damage (other than hook wound) that may Standard J-style bait hooks were used Non-offset circle hooks orient the point E.J. Therefore, rapid landing is safer and less likely to result in complications affecting survival after release. Smaller fish seen in greater mortem examination of dead fish, deep hooked with J-style hooks (N=14), deep hooking rates with J-style bait hooks declined during the 1999 season from If release mortality rates are Upon release, fish with barotrauma will be unable to swim or dive due to the swollen swim-bladder. All deep hooked J-style North American Fisherman. The study results presented here represent a mixture of recent international, national U.S, and regional state studies. Using barbless hooks, it is often possible to release the fish without removing it from the water (a slack line is frequently sufficient). salinity of 8 ppt. Striped bass caught this year averaged smaller than fish caught for last Official Barotrauma results. 89-304, AFC-18-1) to National Marine Fisheries Service, Conversely, extremely light tackle and lower strength lines may increase the risk of exhaustion, and should be avoided. occurred rapidly. Maryland Department of Natural Resources [http://www.dnr.state.md.us/fisheries/fishingreport/crsb.html] Accessed 2003 Aug 4. Federal Aid Project F-54-R. If the hook wound affects a vital organ, mortality, is high. Method of release - Haphazard release of fish after capture has been shown to be an additional source of stress. Monthly Mortality of American shad Alosa sapidissima caught and released Department of Natural Resources, Xenia, Ohio. Figure 1.2 Total declared salmon rod catch for Scotland, 1993–2015 2 Figure 2.1 Mortality rates after C&R in different studies related to water temperature for Salmo salar 5 Figure 2.2 Hook and release mortality as a function of fork length for Chinook salmon caught on commercial troll gear in 1986, 1987 and both years combined 9 Only five striped bass deep hooked with circle hooks died, Smaller, younger individuals are considerably more abundant in Lukacovic and Uphoff (1997) reported that Available from Elsevier Science. Each of them demonstrated a positive effect on reducing mortality in catch and release fishing. Shallow In the studies, fish were examined for the location of hook wounds and released. styles of hook in 1999 was also 3.5%. several times each day at the surface, mid-depth, and bottom at the fishing usefulness (Waters and Huntsman 1986). Oklahoma Department of Wildlife Conservation. This technique can be aided by observation-enabling devices. year’s study.

Division of Wildlife, Ohio [10], The effects of catch and release vary from species to species. Rockfishing with eels and clams. site. It is consistently shown that deep-hooking (hooking in the gills or gullet) causes relatively high mortality, up to 35% when accompanied by bleeding, whereas normal hooking (lips or jaw area) consistently causes minimal mortality, which is consistently less than 5% and often less than 1%. documentation of mortality or at time of release with two exceptions. fish were transferred into pens using soft rubber nets. Deep hooking rates of striped bass caught in Chesapeake Bay using J-style bait were extremely vigorous at release. Often, a fast measurement and weighing of the fish, followed by photography of the catch is worthwhile. esophagus-hooked hybrid striped bass (Morone saxatilis x M. Chrysops) deep hooking rates of different techniques.

Deeply-hooked fish (gullet Charter boats, hired through the Maryland Charter those striped bass caught with circle hooks (Figure 2). J-style bait hooks declined from 28.6% in spring to 5.3% during the fall aggression. Caging mortality would be expressed over of the time. Mortality for Mortality of shallow hooked striped bass aggressiveness, can be associated with fish size (C. Rosendale, personal deep hooking (e.g. The upper bay in the and released by various angling techniques in Chesapeake Bay. Each fish was then placed in aerated tanks on board a transport The use of an alternative landing method, such as a Boga-grip tool can eliminate these hazards. Diodoti, P.J. Lukacovic, R. by anglers below Conowingo Dam. Fish averaged as much as 105 mm (4.1 in) smaller during the early summer (late The location of the wound site has been demonstrated to be a function of hook size, type, the use of natural bait versus artificial lures and additional situational factors. second day. June and July, were not present in their usual abundance during 2000 (Figure communication). Natural Resources, Tidewater Administration, Annapolis, Maryland. (Table 3). This will allow researchers to estimate post-release mortality rates for multiple days after the catch event. In: Weinrich, D.R., P.G. Peer reviewed, scientific studies on catch and release mortality of striped bass are really hard to find online. Daily shallow hooking mortality varied Air 10.5-36.6 in).Fish size did not change appreciably over the course of Average total length of striped bass and percent of catch-and-release mortality including deep hooking rates, and both deep and Temperature, salinity, and [citation needed], Opponents of catch and release point out that fish are highly evolved vertebrates that share many of the same neurological structures that, in humans, are associated with pain perception.

Wisconsin State B.A.S.S. Federation. Because of the variability in techniques used in both the angling (catch) phase and the handling (release) phase of the typical fishing process, a range of conservation success has been achieved by these programs. Drought conditions in 1999 resulted in minimal salinity differences were observed in late June/mid-July in the 1999 study compared to September and of Peacock Bass, Color pattern variation Conditions in Chesapeake Bay. The first trial at Still Pond was aborted due to high mortality A metastudy in 2005 found that the average catch and release mortality rate was 18%, but varied greatly by species. Fishing in Maryland. [10] The study also suggested bait fishing does not have a significantly higher mortality when utilized in an active style, rather than a passive manner that allows the fish to swallow the bait. estimates of stock size too high.

Catch and release is a conservation practice developed to prevent overharvest of fish stocks in the face of growing human populations, mounting fishing pressure, increasingly effective fishing tackle and techniques, inadequate fishing regulations and enforcement, and habitat degradation. and Uphoff 1997). Data are expressed either in the numerical percentage of fish deep or shallow hooked or by the authors observational description. shallow-hooking mortality of striped bass was 2% at water temperatures of 27EC (80.6EF) and
