Feeding And Managing Sheep In Dry Times, Ian Mcfarland, Mandy Curnow, Mike Hyder, Brian Ashton, Danny Roberts

Bulletins 4000 -

Feeding sheep is a significant cost to any sheep or mixed farm enterprise in southern Australia. The cost is usually managed by annually sourcing feed on-farm. However, this feed source can become scarce when we experience unusual dry spells within seasons (termed a 'dry season', such as a dry winter or spring), a late break to the season, a drought year, or even worse, successive drought years.

Climate change research suggests that southern Australia will experience higher annual temperatures and a decline in mean growing season rainfall (particularly winter and spring) over the coming decades. This will affect the productivity …

Tb194: Hemisgrapsus Sanguineus (Asian Shore Crab) As Predator Of Juvenile Homarus Americanus (American Lobster), Anna Demeo, John G. Riley

Technical Bulletins

Hemigrapsus sanguineus, commonly known as the Asian shore crab, was first discovered on the east coast of the United States in New Jersey in 1988. The spread of this invasive crab has been rapid, and it is now abundant along a large portion of the mid-Atlantic and southern New England coast. Further, an invasion of H. sanguineus into New Hampshire and southern Maine is in its preliminary stages. The introduction of this crab to North America could potentially affect a variety of native species. Numerous studies have examined the predation of H. sanguineus on blue mussels, snails, and other bivalves. …

Tb193: The Cost Of Producing Milk In Maine: Results From The 2005 Dairy Cost Of Production Survey, Lisa A. Bragg, Timothy J. Dalton

Technical Bulletins

This report summarizes the results of the 2005 Dairy Cost of Production survey implemented by The University of Maine and the Maine Milk Commission. This study summarizes data collected over the 2004 production year. Funding for this report was provided by the Maine Milk Commission. Analysis and discussion of the data in this report centers on an industry-wide group and three smaller sets called clusters. Cluster analysis attempts to identify groups of farms from within the sample of survey respondents that have relatively homogenous characteristics.

Wild Dog Management: Best Practice Manual, Peter Thomson, Ken Rose, State Wild Dog Management Advisory Committee

Bulletins 4000 -

Wild dogs (all wild-living dogs including pure-bred dingoes, hybrids, and domestic dogs running wild) are one of the major pest species impacting on grazing industries across mainland Australia. In this Manual, the text refers to dingoes where the information is derived from studies of essentially pure dingoes. Elsewhere the text usually refers to the more generic term, wild dogs. The information in this Manual is based on scientific studies, including detailed evaluations of techniques and strategies, as well as considerable practical experience from doggers, Department of Agriculture and Food staff and land managers. Much of this Manual focuses on sheep …

Mycobacterial Infections In Striped Bass (Morone Saxatilis) From Delaware Bay, Christopher A. Ottinger, J. Jed Brown, Et Al, Martha Rhodes, Howard Kator, David T. Gauthier, Wolfgang K. Vogelbein

VIMS Books and Book Chapters

Much of what is known of mycobacteriosis in wild striped bass from the mid-Atlantic region of the United States is based on our observations from Chesapeake Bay and its tributaries, where high infection prevalence and lesioned fish are frequently observed. Comparatively, the occurrence and severity of mycobacteriosis in striped bass from watersheds adjacent to Chesapeake Bay are relatively unknown. This study represents the first report on mycobacterial infection in striped bass harvested from two sites in Delaware Bay.

Epizootic Mycobacteriosis In Chesapeake Bay Striped Bass: What Is The Fate Of Infected Fish?, Wolfgang K. Vogelbein, John M. Hoenig, David T. Gauthier

VIMS Books and Book Chapters

Striped bass (Morone saxatilis) in Chesapeake Bay, USA, are currently experiencing an epizootic of mycobacteriosis. Visceral disease prevalence in resident fish exceeds 50% and prevalence of skin ulcers can exceed 30% in some areas. Two primary hypotheses regarding emergence of this chronic bacterial disease propose that anthropogenic stressors constitute important underlying modulating factors

Farming For The Future Self-Assessment Tool (Sat), Department Of Agriculture And Food, Western Australia, Danielle England, Rebecca Ashley Jones, John Noonan, Jon Warren

Bulletins 4000 -

Western Australian produce is some of the cleanest, safest and most reliable in the world. It is also being produced in an increasingly sustainable manner as our primary producers adopt documented and industry agreed, current recommended practices. International markets and local consumers want to be confident that their goods have been produced in a sustainable manner.

Farming for the Future now gives Western Australian producers a process to demonstrate this. Farming for the Future is working with industry to identify relevant, scientifically valid and measurable sustainable practices. These on-farm practices are being aligned with business, community and government plans for …

The Ecology Of Mycobacteria Infecting Striped Bass (Morone Saxatilis) In Chesapeake Bay: A Research Plan, Howard Kator, Martha Rhodes, David Gauthier

VIMS Books and Book Chapters

The ecology of mycobacteria in estuarine and marine waters remains poorly understood. The current epizootic in Chesapeake Bay striped bass and newly described pathogens Mycobacterium shottsii and M. pseudoshottsii raise ecological questions that if answered can improve our understanding of the pathogenesis of mycobacteriosis in this fish species.

Epizootiology Of Mycobacteriosis In Chesapeake Bay Striped Bass (Morone Saxatilis): Large-Scale Field Survey, David T. Gauthier, Robert Latour, Wolfgang K. Vogelbein

VIMS Books and Book Chapters

Striped bass in Virginia and Maryland waters of Chesapeake Bay are experiencing an ongoing epizootic of mycobacteriosis. Visceral disease prevalence exceeding 50% has been reported in several locations by various authors, and skin lesion prevalence exceeding 30% has been observed. The high prevalence of skin lesions observed in Chesapeake Bay striped bass is unusual and has not, to our knowledge, been reported previously in wild fishes.

Nematodes In Western Australian Vineyards, Vivien Vanstone, Neil Lantzke

Bulletins 4000 -

Nematodes are worm-like microscopic animals that live in the soil. There are numerous soil-inhabiting nematode species, but not all are harmful to plants. Some nematodes are plant-parasitic, feeding on and damaging roots, including those of grapevine. Feeding activities of these nematodes reduce the vine’s ability to take up water and nutrients from the soil, leading to lack of vigour, symptoms of nutrient deficiency, wilting, lower yield, vine decline and, in severe cases, vine death. Nematode feeding sites can also lead to entry of other disease-causing organisms (e.g. fungi or bacteria), resulting in rapid vine decline.

Nematodes can survive in the …
