Project number: 1993-225
Project Status:
Completed
Budget expenditure: $13,750.00
Principal Investigator: Martin Line

Objectives

1. To determine the optimal composting conditions for the starfish waste
2. To determine the effect of composting on the saponin toxin present in the starfish
3. To determine levels of faecal coliforms and heavy metals folowing composting
4. To assess the nutrient value and electrical conductivity (salinity) of the resultant compost
5. To demonstrate the effect of the resultant composts on the growth of two plants (lettuces anf radishes) in a glasshouse trials

Value adding to fish processing waste through aquafeed development

Project number: 1999-424
Project Status:
Completed
Budget expenditure: $40,000.00
Principal Investigator: Geoff Gooley
Organisation: Agriculture Victoria
Project start/end date: 24 Jan 2000 - 30 Jun 2001
Contact:
FRDC

Objectives

1. To undertake an audit of seafood, fisheries and other aquatic "waste" biomass within relevant Victorian industry to characterise the availability and condition of such resources with potential for utilisation within relatively low-cost, semi-refined compound aquafeed development.
2. To undertake an analysis of nutritional, toxicant and pathogenic condition of selected waste resources with potential for utilisation in such aquafeeds.
3. To describe the physical, mechanical and production process requirements of such waste resources and identify associated economic parameters relevant to the development of viable "waste" aquafeed production capability within Australia.

Summary

The management and disposal of solid wastes from seafood processing, food manufacturing and allied industries is a major economic and environmental issue for Australian industry.   Large quantities of wet waste of this nature are routinely disposed of to landfill at considerable cost to industry.  Some companies have developed markets or alternative uses for their wastes (such as petfood, bait, pig food or fertilisers) to avoid or offset the costs of disposal, but generally the wastes are supplied free of charge to secondary users and there is limited opportunity for downstream value-adding.

The utilisation of seafood, aquatic and other food processing wastes as a replacement for imported fishmeal in aquafeed production is the main focus of this project.   The availability of locally-produced formulated feeds using these otherwise wasted resources would provide a firm base to underpin current and future aquaculture production in Victoria and indeed Australia.

The study emphasised the need for a multi-pronged approach to determine the suitability of ingredients for incorporation into fish diets.  In all cases, the findings have to be confirmed through growth trials, prior to possible commercialisation.
