Integrated multi-trophic aquaculture systems: a solution for sustainability

Marine aquaculture of high value species such as fish is generally reliant on external food supplies and has a negative impact on water quality, generating high organic and nutrient loadings. Integrated multi-trophic aquaculture offers a solution to reduce environmental impact of farming systems, culturing complimentary species that can recycle nutrients and reduce nutrient pollution while generating additional products for sale. This article looks at species selection and integration of trophic levels in system design.

Production of tubifex - a new dimension of aquaculture in feeding juvenile fish

The use of sludge or ‘tubifex’ worm, Tubifex tubifex, as a live food for juvenile fish has been long practiced in farmers’ fields and it is an important fish food for spawn rearing. The cost of tubifex worm becomes prohibitive in the dry season, when supplies are limited. We conducted trials to test the feasibility of culturing tubifex using a selection of agro-industrial wastes. Net biomass production was highest using rice mill sludge as a food source, over a culture period of 20 days.

World Brackishwater Aquaculture Conference, 23-25 January 2019, Chennai, India

BRAQCON 2019 wil cover latest research and development in the broader themes of the conference in the form of special sessions, contributed papers, expert group discussions and brainstorming on issues facing aquaculturists and ecosystem managers in India and around the world. The conference themes include: Brackishwater ecosystems, estuarine biodiversity and conservation; aquaculture production systems; larviculture; fish and shellfish nutrition; environment and climate change; aquatic animal health; socio-economic and livelihood issues; and aquaculture genetics and biotechnology.

Pre-pupae (larvae) of black soldier fly - a potential alternative protein source for aquaculture feeds

Insects form a natural food source for many aquatic animals. This and the presence of chitinase makes insect meals a logical alternative to fish meal in the formulation of aquaculture diets. Insect meals have also been shown to allow for enriching through dietary intake. Of particular interest has been the use of black soldier fly larvae. This article reviews the life history and potential of black soldier fly larval meal to replace fishmeal used in fish diets.
