Video on Climate Risk Reduction in Aquaculture
(2020)Type: VideoJust like feed, lime, fertilizer, and so on, weather is an input for aquaculture. We grow fish better in good weather. Unfavorable weather events hamper the growth of fish. This is a risk for all farmers, but our farmers ... -
On-farm epidemiological surveillance of genetically improved farmed tilapia (GIFT) cultured at floating net cages in Pahang, Malaysia
(2020)Type: Journal ArticleIncidence of streptococcosis, parasitic infestation and Tilapia Lake Virus (TiLV) outbreaks in tilapia aquaculture were reported worldwide, affecting the production and poses a significant threat to sustainable aquaculture. ... -
Practical training manual: Tilapia breeding and all-male fry production
(2020)Type: ManualThis is an updated second version of an English language training manual which details how to breed tilapia in synchronous batches and to produce all-male tilapia seed. -
Better management practices for monosex tilapia seed production: An illustrated guide
(2020)Type: BookThe booklet explains the better management practices (BMP) for producing high-quality genetically improved farmed tilapia (GIFT) monosex seed. These simple and low-cost methods have been tested and proven over five years ... -
Distinguishing between Nile tilapia strains using a low-density single-nucleotide polymorphism panel
(2020)Type: Journal ArticleNile tilapia (Oreochromis niloticus) is among the most important finfish in aquaculture, particularly in Asia. Numerous genetically improved strains of Nile tilapia have been developed and disseminated through formal and ... -
Climate smart culture of genetically improved tilapia

Sex determination in the GIFT strain of tilapia is controlled by a locus in linkage group 23
(2020)Type: Journal ArticleTilapias (Family Cichlidae) are the second most important group of aquaculture species in the world. They have been the subject of much research on sex determination due to problems caused by early maturation in culture ... -
Practical training manual: Tilapia breeding and all-male fry production (Burmese Version)
(2020)Type: ManualThis is an updated second version of an Myanmar language training manual which details how to breed tilapia in synchronous batches and to produce all-male tilapia seed. -
Can individual feed conversion ratio at commercial size be predicted from juvenile performance in individually reared Nile tilapia Oreochromis niloticus?
(2020)Type: Journal ArticleFeed conversion ratio (FCR), the ratio between feed intake and body weight gain, is of major interest for improving aquaculture sustainability through reduced feed costs and environmental impacts. Demonstrating whether FCR ... -
Genotype by environment interaction between aerated and non-aerated ponds and the impact of aeration on genetic parameters in Nile tilapia (Oreochromis niloticus)
(2020)Type: Journal ArticleA major problem in smallholder Nile tilapia (Oreochromis niloticus) farms is that the achieved production is much lower than under optimal management. One of the main environmental factors contributing to lower production ... -
A systematic literature review of the major factors causing yield gap by affecting growth, feed conversion ratio and survival in Nile tilapia (Oreochromis niloticus)
(2020)Type: Journal ArticleProductivity among small‐ and medium‐scale tilapia farms varies considerably. The difference between the best performers and lower ones (yield gap), is affected by differences in growth rate and feed conversion ratio (FCR). ... -
Effect of dietary protein level on fish growth, economic and ecological performance of three types of feed for Nile tilapia (Oreochromis Niloticus)
(2020)Type: Internal ReportWith a growing world population, food production needs to increase as well. Part of the human diet is fish, and with world fisheries declining, the aquaculture industry is increasing. Nile tilapia is a major aquaculture ... -

(2020)Type: ManualThis manual provides a comprehensive step-by-step guide to running a tilapia hatchery operation. It includes advice on site selection, site preparation, hatchery design and construction, farming practices (broodstock ... -
Genetic parameters for resistance to Tilapia Lake Virus (TiLV) in Nile tilapia (Oreochromis niloticus)
(2020)Type: Journal ArticleTilapia Lake Virus (TiLV) is one of the primary disease concerns for tilapia farming, with mass mortality events and biosecurity restrictions threating aquaculture in several continents. Selective breeding for improved ... -
Dietary non-starch polysaccharides influenced natural food web and fish production in semi-intensive pond culture of Nile tilapia
(2020)Type: Journal ArticleDietary 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 ... -
