The Pennsylvania Fish and Boat Commission has deep roots in the Spring Creek Watershed, and to many employees the watershed is both their workplace and home. Three very important fish culture facilities are located on lands adjacent to Spring Creek. These include the Bellefonte trout production station and the Upper Spring Creek warm water/cool water propagation facility, and the combination trout produc­ tion station and world-renowned fisheries research station at Benner Spring. The Pleasant Gap Fish Culture Station is also located on the headwaters of the Logan Branch of Spring Creek, together with the headquarters of two of the Commission's largest Bureaus: Fisheries, and Property and Facilities Management. The H. R. Stackhouse School of Fishery Conservation and Watercraft Safety, which serves as the training center for Commission employees and volunteers, is also located adjacent to Spring Creek, together with a firearms training center for conser­ vation officer instruction. The best known section of Spring Creek is the world-famous Fisherman's Paradise, a specially regulated one-mile length of stream adjacent to the Bellefonte hatchery. Farther downstream, on lands owned by the Commission, is the Spring Creek Slalom Course, which is heavily used for training and recreation by kayak and canoe enthusiasts. The borough of Bellefonte maintains a trout exhibition area adjacent to the Tallyrand public park where the stream passes through the center of the commu­ Edward R. Miller, P.E. nity, and farther upstream the flowing waters are the center of attraction of the Executive Director College Township park in Houserville. Pennsylvania Fish & Boat Commission Spring Creek and its unique valley has been much abused over the years as human activities and heavy development have taken place on its watershed. It has been resilient, however, and because of the concerns and efforts of many it has been able to survive and maintain much of its high water quality and productive fishery habitat. Over the years the Commission has continuously sought and encouraged greater public control of Spring Creek, and today the Commonwealth is the largest single property owner on the stream. Just recently the Commission negotiated with the Allegheny Power System for title of Spring Creek and much of its adjacent banks from Bellefonte to Milesburg. This lengthy stretch is strong evidence of the Commission's long-standing efforts. The area includes Commission lands at the Paradise and the Bellefonte and Upper Spring Creek hatcheries, and Commonwealth lands under the control of the Pennsyl­ vania Department of Justice that are leased to the Commission. Other public park lands, together with several private property owner agreements and Penn State University lands, give even more public access to Spring Creek's banks. Recently, the stream was reclassified to High Quality Coldwater Fishery, which helps protect it from further degradation. Meanwhile, efforts currently under way to upgrade sewage treatment at two existing plants, coupled with accelerated efforts by the U. S. Environmental Protection Agency to clean up toxic wastes at the Reutgers- Nease plant, are encouraging factors for the entire watershed. The Commission's long-standing and very close relationship with Spring Creek prompted the Pennsylvania Fish and Boat Commission on April 13, 1992, to autho­ rize the staff to continue efforts to acquire other important sections of Spring Creek. If successful, these acquisitions will further extend public control of the Spring Creek corridor and guarantee that more of this unique natural resource will be protected and available for public enjoyment. It is an historic decision that merits everyone's support. Pennsylvania June 1992 Vol 61 No. 6 Fish & Boat Commission Pennsylvania William J. Sabatose President Brockport J.

Fish in Renaissance Dietary Theory Ken Albala It is clear that the rising consumption of fish in recent decades can be ascribed in large measure to the favorable verdict of physicians and nutritionists. Fish offers a nutritional profile that fits in well with current dietary principles. Was this not also the case with past nutritional theory? Did the advice of physicians formerly dissuade consumers from eating fish, so that a modern revival was required? This paper will attempt to answer that question by examining European nutritional theory from the invention of printing to the mid-seventeenth century to establish the possible origin of fish aversion. The story, however, is not simply that past physicians banned fish from a healthy diet; the situation is far more complicated.

  • Aquaculture in Africa = La Pisciculture En Afrique
    459 Chapitre 22 AQUACULTURE IN AFRICA LA PISCICULTURE EN AFRIQUE P. B. N Jackson 1 - INTRODUCTION Though aquaculture is of considerable antiquity especially in the Far East, and even though the first record of fish in ponds is from an Egyptian bas-relief of yet greater age @mignon, 1962 ; Balarin & Hatton, 1979), fish farming in Afiica is an activity of very recent origin. This is because until recently, human populations in Afiica were small enough for their needs to be met by the natural reproduction of fish, without having to breed and grow them artificially. SO a tradition of the culture of fish and other aquatic organisms never became established in Aftica as it did in the Orient. However though fish were not held in captivity, practices such as the trapping of fish behind fentes or weirs, which are widespread in many areas, and espe- cially the concentrating of fish in lagoons or floodplains in Benin by means of «acadjas» or fish-parks made of brushwood (Welcomme, 1971), are certainly steps in this direction. Given time, therefore, a fish culture tradition may have evolved independently in Africa, but events were overtaken and the process hastened by the importation of culture techniques from elsewhere. Such importations generally began with the techniques of breeding sport angling fish, parti- cularly trout and vatious bass species,also the «Sandre» (Stizostedion Iucioperca into Morocco (J. Arrignon pers. com.), for sport fishing, but even the earliest hatcheries for this purpose are less than a hundred years old. The breeding of fish for food is still more recent and correlated with the great increases in human populations, whose impact, especially the need to provide more food, only began to be felt well into the twentieth Century.

The animal remains enable the reconstruction of the food procurement strategies of the Dutch inhabitants of the fort and document the fauna at a time when the island’s original fauna had apparently already suf- fered heavily from human interference and from the negative impact of introduced species. The animal remains do not include any bones from the dodo, or other endemic birds, and neither is there evidence for the exploitation of the large, endemic terrestrial tortoises, also now extinct. Dugong, which are locally extinct nowadays, and marine turtles were also exploited as food, but the major meat providers were the introduced mammals: cattle, pigs, and especially, goat and Java deer.

    Biodiversità Mediterranea – Internazionale Scienze Agrarie, Alimentari e Forestali BIO/06 Mining extraction in the ocean depths: a baseline to understand and reduce acoustic impact on biodiversity PhD CANDIDATE PhD COORDINATOR MANUELA MAURO PROF.SSA MARIA ANTONIETTA GERMANA’ SUPERVISOR CO-SUPERVISOR PROF.SSA MIRELLA VAZZANA PROF.SSA ISABEL PÉREZ ARJONA PROF. EDUARDO JORGE BELDA PÉREZ DOTT.SALVATORE MAZZOLA CICLO XXXII 2020 2 To my mom, to her dream began reality 3 4 Abstract Throughout history, man has exploited the earth's mineral resources for its survival and for technological development without regard for their regeneration. Given the growth of the world population and given the fall in resources, man started looking for new deposits, which were found in 1960s in the ocean depths. Humankind then began to consider extracting minerals from these deposits and this gave origin to Deep Sea Mining (DSM). The consequences of mining activities in the deep sea are not entirely known and the effects can be varied: noise pollution, light pollution, chemical pollution, habitat destruction, habitat fragmentation and the loss of species which we consider the basis of many life systems. The acoustic impact of these activities could have significant consequences on marine species; nevertheless, this has been the most overlooked issue to date. The aim of this PhD project was to provide baseline knowledge of possible acoustic impacts of DSM on biodiversity before mining begins. In order to do this, the PhD project was organised into 3 different stages. First, during an indoor experiment, the biochemical responses of invertebrates Arbacia lixula and Mytilus galloprovincialis subjected to acoustic stress were analysed.

  • Dismantling Media Produced Fear Toward Predators
    Running head: PREDATOR RELATIONS IN THE MEDIA i Dismantling media produced fear toward predators Nicole Pavla Schafer University of Otago 2011 PREDATOR RELATIONS IN THE MEDIA ii Abstract Top predators like the shark were once revered as guardian deities - now they are demonized as terrorizing killers. While once respected and worshipped they are now considered to be the epitome of evil and malevolence. This transformation in our emotional response and perception is due in large part to the media. The media creates fear with their use of framing, images, and agendas that emphasize the sensational. Fear is a motivating force and a compelling emotion used by the media to increase ratings and keep the reader or viewer interested. Predators are receiving negative publicity and it is impairing conservation efforts launched on their behalf. A change in the media’s treatment of predators and a significant change in their audience’s expectations may be the only way to develop a more realistic and appropriate public attitude toward predators. This thesis will explore this predicament by creating an understanding of what fear is, how it is generated, and how the media uses it, before suggesting solutions that might decrease sensationalism and increase the factual content of media reports. The creative component of the thesis, the twenty-five minute film Tangled Waters, illustrates how the small community of Dunedin, New Zealand brought an end to a forty-year practice of shark netting. In 1967, Dunedin placed anti-shark nets off three beaches to protect beachgoers from great white sharks. Ratepayers came together and campaigned to not only save themselves $38,000 a year of council spending, but also to positively support their local marine wildlife.
