Genetic improvement of Israeli blue (Jordan) tilapia, Oreochromis aureus (Steindachner), through selective breeding for harvest weight
(2014)Type: Journal ArticleGenetic parameters and selection responses were obtained for harvest body weight of blue tilapia (Oreochromis aureus) from data collected over three generations in a selected population. A total of 18 194 records representing ... -
Effects of stocking density on production and economics of all-male tilapia (Oreochromis niloticus) culture in a rain fed rice-fish ecosystem
(2014)Type: Journal ArticleEffects of stocking density on the growth, production, and economics of all-male tilapia (Oreochromis niloticus) were investigated in a rain-fed rice-fish ecosystem for a period of 120 days. Fish were stocked at the rate ... -
Effects of C/N ratio and periphyton substrates on pond ecology and production performance in giant freshwater prawn Macrobrachium rosenbergii (De Man, 1879) and tilapia Oreochromis niloticus (Linnaeus, 1758) polyculture system
(2015)Type: Journal ArticleThe production performances of giant freshwater prawn Macrobrachium rosenbergii and Nile tilapia Oreochromis niloticus in C/N-controlled periphyton-based polyculture systems were evaluated in triplicate. The result of this ... -
Portable ponds for communities in need
(2015)Type: Journal ArticleTo address the extreme food insecurity of the poor households in Bangladesh, WorldFish has designed a portable small pond which can hold fish in it and at the same time, provide water for horticulture. Trials began in 2014 ... -
Are trunk lateral line anomalies and disoriented scale patterns in European seabass (Dicentrarchus labrax) influenced by genetics?
(2015)Type: Journal ArticleDifferent kinds of defects are observed on farmed fish, and while a lot of research has concentrated on skeletal abnormalities, little is known on scale anomalies. In this paper, a survey for lateral line shape anomalies ... -
Phenotypic and genetic parameters for body traits in the giant freshwater prawn (Macrobrachium rosenbergii) in India
(2017)Type: Journal ArticlePhenotypic and genetic parameters were estimated for three body traits (harvest weight, carapace length and standard length) and for adult male morphotypes of the giant freshwater prawn Macrobrachium rosenbergii in a fully ... -
Individual growth monitoring of European sea bass larvae by image analysis and microsatellite genotyping
(2014)Type: Journal ArticleThe aims of the present study were to develop non-lethal methods to identify individual fish larvae and post-larvae before tagging and accurately follow their growth characteristics. European sea bass (Dicentrarchus labrax) ... -
Response to selection for growth in an interspecific hybrid between Oreochromis mossambicus and O. niloticus in two distinct environments
(2014)Type: Journal ArticleThe development of a saline tolerant tilapia strain able to grow fast is of importance in the Philippines, where 240 000 ha of brackish water ponds are available. To this end, founder hybridization between Oreochromis ... -
Improving feed efficiency in fish using selective breeding: A review
(2017)Type: Journal ArticleImproving 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 ... -
Growth and economic analysis of freshwater prawn, Macrobrachium rosenbergii (de Man), produced with feeds substituting sunflower cake for fish meal, soya bean meal and mustard oil cake
(2017)Type: Journal ArticlePrawn farming has grown in popularity since its introduction to Bangladesh in the early 1980s and is now widely practised in coastal areas. In Bangladesh, the main fish feed ingredients for prawn farming are rice bran, ... -
Indonesian aquaculture futures: Evaluating environmental and socioeconomic potentials and limitations
(2017)Type: Journal ArticleIndonesia is the worlds second largest seafood producer, but capture fisheries landings have slowed down over the last decade. In response, the Indonesian government has also set ambitious targets for expanding the aquaculture ... -
Discovery and biological relevance of 3,4-didehydroretinol (vitamin A2) in small indigenous fish species and its potential as a dietary source for addressing vitamin A deficiency
(2017)Type: Journal ArticleDiscovered in the late 1920s, 3,4-didehydroretinol (DROL, vitamin A2) plays a significant biological role in freshwater fish. The functions of this vitamin have been investigated but to a far lesser extent than those of ... -
