Exploring the trophic structure in organically fertilized and feed-driven tilapia culture environments using multivariate analyses
Type: Journal Article
Reports of similar yields in manure and feed-driven tilapia culture environments raise questions on food utilization in these environments. The possibility that similar production rates are because of utilization of different ...
The potential for crop rotation in controlling diseases in shrimp culture
Type: Journal Article
The use of antibiotics and other chemicals in controlling shrimp pathogens become ineffective as the strains grow more resistant to these chemicals. Moreover, the bacterial pathogen (Vibrio harveyi) produced biofilm coating ...
Aquaculture in action: reducing the need for feed
Type: News Item/Press Item
A novel aquaculture feeding concept is exploiting the pond ecosystem to encourage farmed fish and shrimp to ingest naturally occurring food alongside feed – a system that has the potential to reduce both production costs ...
Feeding both pond and fish: A pathway to ecological intensification of aquaculture systems
Type: Other
The nutritious pond concept is a novel approach that enables the pond itself to contribute significantly to the diet of the farmed fish/shrimp. Our research shows that feeding the pond by balancing the carbon-to-nitrogen ...
Dietary non-starch polysaccharides influenced natural food web and fish production in semi-intensive pond culture of Nile tilapia
Type: Journal Article
Dietary non-starch polysaccharides (NSP) changes the nutrient digestibility and faecal characteristics in fish. This study assessed the effect of the type of dietary NSPs on fish production and the contribution of natural ...
In situ fatty acid production supports shrimp yields in diets lacking fish oil and fishmeal
Type: Journal Article
Using capture fishery‐derived fish oil and fishmeal in aquafeeds is unsustainable. This study mimicked semi‐intensive shrimp ponds, including primary producers, in mesocosm tanks. Fatty acid mass balances were computed to ...
CGIAR Research Program on Fish Agri-Food Systems: A synthesis
Type: Brief
The fish agri-food system connects supplies of fish and other aquatic foods through multiple pathways and scales to diverse consumers across the planet and is a key component of the global agri-food systems. Fish and other ...
Livelihood Impacts of ponds in Asia - opportunities and constraints
Type: Book Chapter
Ponds are traditional multipurpose resources accessed by households and communities, and are increasingly beingprioritised for aquaculture. High consumption of aquatic animals and declines in natural stocks has stimulated ...
Effects of carbohydrate sources on a biofloc nursery system for whiteleg shrimp (Litopenaeus vannamei)
Type: Journal Article
In biofloc technology carbohydrate is added to stimulate the biofloc growth, the latter helps to improve water quality, reduce the need for water exchange and may serve as natural shrimp feed. The large diversity among ...
Effect of dietary carbohydrate to lipid ratio on performance of Nile tilapia and enhancement of natural food in pond aquaculture
Type: Journal Article
This study tested the effect of two diets differing in carbohydrate to lipid (CHO:LIP) ratio (4.7 vs. 19.5 g/g) on the contribution of natural food and the total fish production in tilapia ponds. Eight ponds, each divided ...
