HOFFMANN'Smost recent book, Fishers' Craft & Lettered Art: Tracts on Fishing from the End of the Middle Ages, was released late last year by University of Toronto Press. The book contains editions, English translations, and analysis from social, cultural, and environmental perspectives of the three oldest European extended tracts on fishing. Professor Hofjcmann discusses the history offishing in popular culture and outlines the economic and eco- logic considerations necessary for an examination and understanding of these fishing manuals. He further explores how continental fishing traditions were conveyed from oral craft practice into printed culture and proposes that these manuals demonstrate a lively and complex interac- tion between written texts and popular culture. In the book, the tracts are presented in the origi- nal languages with facing-page translations. We are pleased to excerpt the second of the three tracts discussed, "Tegernsee Fishing Advice." To follow in the style of Fishers' Craft & Lettered Art, we first present excerpts from Hofmann's analysis of the manuscript object, then excerpts of the translation of the text itself: EDITOR A Collection of Popular Wisdom from Tegernsee Abbey ONKS AND PEASANTS share words from the essentially oral peasant structions for making a tapered horse- responsibility for a text known culture of the Bavariari and Austrian hair line and for using it with rod and M only from thirteen leaves of a mountains, and thus reports on fishing bait for trout and grayling (fols. single manuscript volume.

  • EVALUATION of BOTANICAL PISCICIDES on NILE TILAPIA Oreochromis Niloticus L
    EVALUATION OF BOTANICAL PISCICIDES ON NILE TILAPIA Oreochromis niloticus L. AND MOSQUITO FISH Gambusia affinis BAIRD AND GIRARD Arsenia G. Cagauan, Marjorie C. Galaites and Lorenz J. Fajardo College of Fisheries and Freshwater Aquaculture Center Central Luzon State University, Science City of Muñoz, Nueva Ecija 3120, Philippines Abstract The study assessed the piscicidal activity of ten locally available plants to two freshwater fishes; Nile tilapia (O. niloticus L.) and mosquito fish (G. affinis Baird and Girard). It focused on the laboratory determination of lethal concentrations (LC50 and LC100) through a static bioassay test. The ten plants tested were ampalaya Momordica charantia, adelfa Nerium indicum, agave Agave cantala, kalamansi Citrus mitis, lagundi Vitex negundo, madre de cacao Gliricidia sepium, makabuhai Tinosphora rhumpii, neem Azadirachta indica, physic nut Jatropa curcas and sambong Blumea balsamifera. Based on the 24-hour lethal concentration (LC100), the plants with the strongest piscicidal activity to Nile tilapia and mosquito fish were makabuhai and kalamansi, respectively. The toxicity to Nile tilapia of the ten plants arranged in the order of decreasing toxicity is as follows: makabuhai (0.82 ml l-1) > adelfa (1.06 ml l-1) > ampalaya (2.59 ml l-1) > kalamansi (5 ml l-1) > neem (12.4 ml l-1) > physic nut (26.67 ml l-1) > lagundi (31.5 ml l-1) > agave (74.29 ml l-1) > madre de cacao (90 ml l-1) > sambong (125.71 ml l-1). For mosquito fish, the toxicity of the ten plants arranged in the order of decreasing toxicity is as follows: kalamansi (3 ml l-1) > makabuhai (6 ml l-1) > adelfa (7.87 ml l-1) > neem (8.31 ml l-1) > ampalaya (13.5 ml l-1) > lagundi (50 ml l-1) > sambong (80 ml l-1) > physic nut (81.67 ml l-1) > agave (102.08 ml l-1) >madre de cacao (117.5 ml l-1).

Danube Research-Consulting S.R.L., 89bis Câmpia Libertății Street, 825200, Isaccea, Romania ‡The first two authors contributed equally to this work. Abstract Huchen or Danube salmon (Hucho hucho, Linnaeus, 1758) is an economically and ecologically valuable salmonid species, among the most endangered fish species inhabiting the Danube basin. Consequently, appropriate conservation measures are required to prevent the species extinction. Although H. hucho is a poorly studied species, there are several studies on other salmonid species regarding fast growth markers. Following these studies, the main purpose of the current study was to determine growth-related SNPs in myostatin gene in H. hucho. Therefore, we analysed 20 aquaculture individuals of same age separated in two groups according length and weight, by sequencing the amplification product of SaMSTNb23 and SaMSTNb33 primers pairs. We also statistically analysed the differences in the development of individuals over time regarding total length, weight and head length. Significantly variations were observed (p < 0.001) for the measured traits in both groups. Regarding the genetic analysis, we observed nine SNPs in the mstn gene structure. Considering these results, it appears that the analysed markers are not appropriate for genetic analysis of growth traits in H.

  • FWP Fish Removal Projects Fish and Wildlife Commission Work Session May 18, 2021
    FWP Fish Removal Projects Fish and Wildlife Commission Work Session May 18, 2021 Fish removal is a common method used to manipulate population densities and species composition of a fishery. Fish removals may be used to reduce competition between species, remove undesirable or invasive species, protect species with elevated conservation risk, or to improve the quality of a sport fishery. Removals are often intended to restore or reintroduce native fish to a drainage or to improve an existing fishery. Most removal projects aspire to improve fishing opportunity by reintroducing species better suited for available habitats or by reducing competition with other species. Tools commonly used by FWP for removal include angling regulations, netting and electrofishing, dewatering, construction of barriers, and use of piscicides/chemicals (Table 1). These are described in more detail below. Table 1: Comparison of fish control or removal methods commonly used for fisheries management. Control Method Advantages Disadvantages Typical Use Angling regulations Allows harvest of Slow, angling pressure often Used where total removal not fish, and less fish inadequate for significant possible or necessary waste change, and many species/sizes not vulnerable Netting and Can allow for Unlikely to eradicate fish and Used in large lakes or rivers where Electrofishing selective removal could harm non-targeted species chemicals not feasible, small streams through bycatch to reduce species competition, or where sensitive/endangered species must be protected Dewatering

  • APPENDIX C Use of Piscicides and Neutralization Compounds
    APPENDIX C Use of Piscicides and Neutralization Compounds Historic Use of Piscicides to Manage Fisheries Fisheries managers rely on a variety of tools to manage and assess fish populations. Historically, these have included the use of piscicides. Two piscicides, rotenone and antimycin A, are currently registered by EPA for general use in the United States under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). By law, the EPA is authorized to register a pesticide only if it will not cause unreasonable adverse effects on human health or the environment. Originally, piscicides were mainly used to control out-of-balance or undesirable fish populations so that sport fish could be stocked for recreational purposes. Today, antimycin and rotenone are used in fisheries management for a variety of purposes, including (Finlayson et al. 2000): • Eradication of nonnative fish, • Restoration of threatened and endangered fish, • Support of recreational fisheries by controlling undesirable fish, • Eradication of fish to control disease, • Quantification of populations of aquatic organisms, • Eradication of competing fish in rearing facilities or ponds prior to restocking. Although physical removal methods (e.g., nets, traps, seines, electrofishing, dewatering, and combinations of physical control techniques) are available for reducing or controlling fish communities, they are generally incapable of eradicating fish (Finlayson et al. 2000). Meronek et al. (1996) review of fish control projects found that success rates for physical removal methods ranged from 33 percent to 57 percent. In most streams, only piscicide applications or complete dewatering can eradicate entire populations of undesirable fish (Schnick 1974). Rotenone Rotenone has been used in the United States to manage fish populations since the 1930s and is the piscicide of choice for application in ponds and lakes.

Received 17 December, 2018: Accepted 7 January, 2019 A 96 h static toxicity bioassay was carried out to examine fish responses and to determine the median lethal concentration (LC50) of Balanites aegyptiaca stem bark extract on adults of Brycinus nurse, Labeobarbus bynni and Labeobarbus intermedius. Experimental fish were exposed to piscicide plant extract of 0.0 (control), 15.0, 17.5, 20.0, 22.5, and 25.0 mgL-1. Fish exposed to these extracts except the control showed symptoms of toxicity including darting, agitated swimming, air gulping, loss of sensitivity and knockdown before death. These responses were much frequent and faster in L. bynni -1 and L. intermedius. The 96 h LC50 values for the different test fishes were 18.99, 20.72 and 20.72 mg L for L. bynni, L. intermedius and B. nurse, respectively. Based on the present investigation, we can conclude that the application of B. aegyptiaca extract causes lethal toxic effects on different fishes even at low concentrations and hence, indiscriminate use of the plant for fishing should be discouraged and regulated in order to protect fish biodiversity lose in the Alitash National Park area.

Apiosoma piscicola, Epistylis lwoffi, Gyrodactylus derjavini were the representative ectobiont species on fish examined. Greater ectobiont richness was observed in April in Poblacnica River. Keywords: wild salmonids, ectobionts, Serbia. 1. INTRODUCTION Up to now, investigations of ectobionts, including parasitic organisms, were not accomplished on the salmonids in Serbia. Parasitic investigations have been done on fish species from eight hill- mountanious watercourses, two lakes and one salmonid fishpond of Sjenicko-Pesterska plateau (Uvac River Basin, south-west region of Serbia) (Cakic, 1992). Also, studies of freshwater fish ectoparasites in lakes of Homolje area have been performed (Nikolic and Simonovic 2002; Nikolic et al. 2006). Health condition of salmonid populations from Serbian waters, graylings above all, has become very important for the past few decades because constructing hydropower objects, reinforced catch and inadequate protection may lead to moving of distribution boundaries in Europe (Jankovic, 2010).
