Code Of Practice For The Use Of Agricultural And Veterinary Chemicals In Western Australia, Peter Rutherford

Bulletins 4000 -

Agricultural and veterinary chemicals are a critically important input to modern farming systems. There is, however an increasing responsibility on the spray operator and his supervisor to use them with utmost safety. An effective way of providing the “rules” of safe chemical use is through a Code of Practice, the concept of which arose because of the increase in new and emerging agricultural industries and their impact on traditional uses of agricultural chemicals.

Introduction: Management Of Sharks And Their Relatives (Elasmobranchii), John A. Musick

VIMS Books and Book Chapters

This publication describes the scientific principles and techniques used for resource management of elasrnobranch fisheries with emphasis on the particular context of elasmobranchs. The management characteristics of these fishes are described - their common bycatch character and their biological constraints on productivity (low growth rate, late maturity and Tow fecundity). Stock assessment of elasrnobranchs is described in the context of rnanagement objectives in a wide management context. Special attention is given to accurate species identification given the prevalent aggregating of landings data across species, genera and often families in this group. Techniques and experiences for tagging elasmobranchs for population estimation …

Shark Utilization, John A. Musick

VIMS Books and Book Chapters

Sharks and their relatives provide a multitude of usable products including: meat, fins, liver, skin, cartilage and jaws and teeth. Unfortunately, tens of millions of sharks taken in fisheries each year have their fins removed and their carcasses discarded overboard (Fowler and Musick, 2002). This practice, called finning, represents a considerable waste as the fins on average make up only about 5 % of the total weight of a shark (Vannuccini, 1999). Such waste is contrary to the United Nations Food and Agricultural Organization (FAO) Code of Conduct for Responsible Fisheries (Article 7.2.2 (g)) which stresses the importance of avoiding …

The State Of The Animals Iii: 2005, Deborah J. Salem, Andrew N. Rowan

In this third, all new, volume in the State of the Animals series, scholars and experts in animal protection examine the challenges facing companion animals, marine mammals, and nonhuman primates and review legal protection for animals here and abroad.

Mortality Estimation, Colin A. Simpfendorfer, Ramon Bonfil, Robert J. Latour

VIMS Books and Book Chapters

Mortality is an essential parameter in understanding the dynamics of any population and sharks are no exception. Without knowledge of how fast individuals are removed from a population it is impossible to model the population dynamics or estimate sustainable rates of exploitation or other useful management parameters.

Reproductive Biology, Christina L. Conrath

VIMS Books and Book Chapters

Several reproductive specializations are found within the elasmobranchs. All elasmobranchs fertilize internally and produce a relatively small number of large eggs. Elasmobranch fecundity generally ranges from one to two offspring produced a year up to a maximum of 300 in the whale shark (Compagno, 1990; Joung et al., 1996). Elasmobranch reproductive strategies include oviparity, aplacental viviparity and placental viviparity (Wourms, 1977). Oviparous species enclose eggs in an egg case and deposit them into the environment, where embryos develop external to the body of the mother . .Embryos remain in the egg case to develop for a period ranging from less …

Tagging Methods And Associated Data Analysis, Robert J. Latour

VIMS Books and Book Chapters

Tagging methods have a long history of use as tools to study animal populations. Although the first attempts to mark an animal occurred sometime between 218 and 201 B.C. (a Roman officer tied a note describing plans for military action to the leg of a swallow and when the bird was released it returned to its nest, which was in close proxiD?ity to the military outpost in need of the information), it is uncertain when fish :"ere first marked (McFarlane, Wydoski and Prince, 1990). An early report published 1? The_ Comp/eat Angler in 1653 by Isaak Walton described how private …

You Can Help Keep Western Australia Free Of Pest Animals, Marion Massam

Bulletins 4000 -

Quite apart from their economic and environmental impacts, the sheer nuisance value that certain pest animals can create for people - even in the shelter of our own backyards - is reason enough to want to keep them out of Western Australia.

Currently our State is free from numerous pest animals that, interstate or overseas, damage crops, spread exotic diseases, endanger the survival of native animals and disturb habitats.

You can help in maintaining this freedom, by being on the lookout for the animals featured on the following pages. As yet, they are either absent from Western Australia or confined …
