Improvement And Evaluation Of Greenlip Abalone Hatchery And Nursery Production. Final Frdc Report - Project 2003/203, Sabine Daume

Fisheries research contract reports

A range of experiments aimed at optimizing broodstock performance and nursery culture of greenlip abalone (Haliotis laevigata) were undertaken in Western Australia. Factors investigated that can potentially influence broodstock performance were natal source (wild-caught or farm-grown) and broodstock diets (red algal diet or formulated diet varying in levels of an important fatty acid). Wild-caught broodstock, feeding mainly on a red seaweed diet, produced eggs with higher concentrations of an important fatty acid, arachidonic acid, whereas farm-grown broodstock, feeding on a commercial formulated diet, altered the concentration of fatty acids of the eggs. Feeding farm-grown broodstock natural diets like …

Identification And Control Of Pest Slugs And Snails For Broadacre Crops In Western Australia, Svetlana Micic, Ken Henry, Paul Horne

Bulletins 4000 -

The numbers of slugs and snails have increased in broadacre cropping in Western Australia with the use of minimum tillage and stubble-retention practices. The organic content of paddocks increases under such systems, providing an increased food source especially to young slugs and snails. Soil moisture content is greater over summer leading to higher survival levels of slugs and snails.

Slug and snail pests in Australia have come from other countries, mainly the Mediterranean region. They damage plant seeds (mainly legumes), recently germinated seeds, seedlings and leaves and can be a contaminant of grain at harvest.

Improved Performance Of Marron Using Genetic And Pond On Using Genetic And Pond Management Strategies, Craig Lawrence Dr

Fisheries research contract reports

Marron (Cherax tenuimanus) are the highest valued freshwater crayfish farmed in Australia. This project addressed the need to increase the profitability of commercial marron farms by improving growth rates and pond management strategies.

Fisheries Occasional Publication 40: A Summary Of Data Collected By The Angler’S Daily Log Book And Fishing Tournament Monitoring Programs In 2004-2006, Kimberley A. Smith, M Hammond, Joshua Brown

Fisheries occasional publications

Catch information and biological samples collected by recreational anglers in daily log books can provide valuable information about local fish stocks. The numbers and lengths of important recreational target species can be used to monitor their abundance and population structure, which can form the basis of fishery stock assessments. In addition, the total composition of the catch and observations about fish health provide measures of local biodiversity and ecosystem health. The Department of Fisheries (DoF) Recreational Angler’s Daily Log Book Program was launched in March 2004 as part of the DoF Research Angler Program (RAP). The current log book format …

Returns To Research And Development Investment Of The Department Of Agriculture And Food Western Australia : Benefit Cost Analysis, 2006-2007, Peter Coyle, Editor, Roslyn Blanchard, Francis Bright, Paul Mattingley, Manju Radhakrishnan

Bulletins 4000 -

Strategic decision making is enhanced by the consideration of benefit cost analyses of many projects. Each year a selection of projects is evaluated to assist in the determination of the most appropriate allocation of funds. This is only one of the methods that are employed by the Department’s Executive to increase market competitiveness and profitability in agriculture and the pastoral industries. This report includes both ex post and ex ante analyses, as they are complementary processes.

Root Lesion And Burrowing Nematodes In Western Australian Cropping Systems, Vivien Vanstone

Bulletins 4000 -

Nematodes are common soil pests that feed on the roots of a wide range of crop plants in all agricultural areas of Western Australia, irrespective of soil type and rainfall. Nematodes multiply on susceptible hosts. Consequently, as nematode populations increase, crop production is limited. Cereal yield losses due to nematodes in Western Australia are in the order of 5 to 15 per cent per annum, but individual losses as high as 40 per cent have been recorded.

Feed On Offer Photo Gallery : For Annual Pastures During The Green Period, Mandy (Catherine Amanda) Curnow, Lifetimewool (Australia)

Books & book chapters

Food on Offer, or FOO, is the amount of pasture available for sheep to eat. It is measured as dry matter per hectare, and then used to budget feed available and stocking rates for a given period.

FOO includes all green material above the ground and it is reported in kilograms of dry matter per hectare (kg DM/ha).
