New Formulae for Food

Synopsis

Aquatic animals have a wide range of feeding habits and dietary requirements, all of which are sustained in the natural food web. Understanding dietary needs and habitat is important to the success of commercial fish farming. The programme examines two examples of the development of artificial diets for fish. The Sharpe brothers’ trout farm in Hertfordshire illustrates how a suitable environment is created to allow trout to thrive. The formulation of an artificial trout food is described by a representative of an animal feedstock manufacturer. The second example shows a salmon farm at Otter Ferry, Argyll, with research being conducted at the Freshwater Fisheries Laboratories at Pitlochry and Almondbank in Perthshire. John Thorpe of the Scottish Department of Agriculture and Fisheries explains how diet regulation is used to increase the salmon’s rate of growth without inducing the onset of maturation, thus improving the yield of marketable salmon.

Notes

NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
