Measuring individual feed efficiency and its correlations with performance traits in Nile tilapia, Oreochromis niloticus
Type: Journal Article
Estimating individual feed intake of fish held in groups has long been a challenge precluding precise knowledge of the individual variation of feed efficiency (FE) in fish. In this study, counts of the number of feed pellets ...
Development of Diversity Arrays Technology markers as a tool for rapid genomic assessment in Nile tilapia, Oreochromis niloticus
Type: Journal Article
The development of genomic markers is described for Nile tilapia, Oreochromis niloticus, using the Diversity Arrays Technology (DArT) genotype-by-sequencing platform. A total of 13 215 single nucleotide polymorphism (SNP) ...
Genetic variation in wild populations and farmed stocks of Nile tilapia (Oreochromis niloticus) in Madagascar
Type: Journal Article
Four farmed stocks and four wild populations of Nile tilapia (Oreochromis niloticus), which was first introduced to Madagascar sixty years ago, were assayed for genetic variation at nine microsatellite loci to determine ...
Fish trait preferences: a review of existing knowledge and implications for breeding programmes
Type: Journal Article
Continued growth of the aquaculture sector will rely on the availability of fish with traits that respond to the needs and preferences of these users along the value chain. Such trait responsiveness requires that fish ...
A systematic quantitative literature review of aquaculture genetic resource access and benefit sharing
Type: Journal Article
The Convention on Biological Diversity provides a framework for countries to implement laws regulating the access, use and exchange of genetic resources, including how users and providers share the benefits from their use. ...
Sibship assignment to the founders of a Bangladeshi Catla catla breeding population
Type: Journal Article
In terms of quantity produced, Catla catla is the sixth most important finfish aquaculture species produced globally in 2015. It is primarily grown in South Asia, often on a small scale in polyculture with other species. ...
Breeding for robustness: Investigating the genotype-by-environment interaction and micro-environmental sensitivity of Genetically Improved Farmed Tilapia (Oreochromis niloticus)
Type: Journal Article
The objectives of this study were (i) to quantify the degree of G x E by assessing the growth performance of Genetically Improved Farmed Tilapia (GIFT) across three countries (Malaysia, India and China) and (ii) to quantify ...
Agonistic behaviour and feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
The main hypothesis of the present study was that an aggressive and dominant fish would eat more feed and would be more efficient. To test this hypothesis, estimations of the relationships between agonistic behaviour, ...
PmPPAF is a pro-phenoloxidase activating factor involved in innate immunity response of the shrimp Penaeus monodon
Type: Journal Article
One of the major steps in the innate immune response of shrimp includes the activation of serine proteinases of the pro-phenoloxidase pathway by the prophenoloxidase activation enzyme (PPAF). In this study, the cDNA encoding ...
Improving feed efficiency in fish using selective breeding: A review
Type: Journal Article
Improving feed efficiency (FE) is key to reducing production costs in aquaculture and to achieving sustainability for the aquaculture industry. Feed costs account for 30-70% of total production costs in aquaculture; much ...
