Polyculture of tropical bivalve mulluscs with tilapia: a potentially profitable solution to predator control and fouling problems
Type: Journal Article
This article gives an account of the beneficial effect of rearing sea water acclimated tilapia with oyster culture.
Observations on gillnet catches of Kariba tilapia, Oreochromis mortimeri from Bumi Basin of Lake Kariba, Zimbabwe
Type: Journal Article
Gillnet catches of Oreochromis mortimeri (Trewavas) were studied in the Bumi Basin of Lake Kariba in 1988 and 1989. Total length (TL) was positively correlated with standard length (SL). The linear relationship between TL ...
Photographic image analysis for morphometric studies of tilapia
Type: Journal Article
Biologists have long employed morphometry as a tool in identification, grouping of populations and stock identification of fish. For tilapias, studies have been made on the variability of morphomeric characters in Egyptian ...
Breeding and propagation of tilapia (Oreochromis niloticus) in a floating hatchery, Gabon
Type: Journal Article
Based on the encouraging results obtained by earlier workers, the concept for a floating hatchery was developed for producing tilapia for both farming and enhanced fisheries in the freshwater lakes and coastal lagoons of ...
Seinability of four strains of Nile tilapia, Oreochromis niloticus, in Chinese ponds
Type: Journal Article
The objective of the current experiment was to examine seinability of four strains of Nile tilapia, O. niloticus, GIFT and Egypt 92, Egypt 88 and Sudan 78. The latter two are normally utilized in China.
On improving the resolution of the recruitment patterns of fishes
Type: Journal Article
It is proposed that the "recruitment pattern" routine of the ELEFAN II program can be modified to allow, in addition to length-frequency data, the use of "restructured" data files. An example, based on Oreochromis niloticus ...
The introduction of exotic fish in Sri Lanka with special reference to tilapia
Type: Journal Article
Introductions of exotic finfish between 1948 and 1953 are reported in this paper, with a brief reference to earlier and later introductions. Exotic fish were introduced principally to develop the potential for aquaculture ...
Investigations on the use of on-farm resources as pond inputs to culture Tilapia rendalli and Oreochromis shiranus on smallholder farms in rural Malawi
Type: Journal Article
Resources available on the majority of smallholder fish farms in the Zomba District of Malawi were tested toincrease smallholder aquaculture production currently limited by a lack of inputs.
Genetic improvement of farmed tilapias: growth performance in a complete diallel cross experiment with eight strains of Oreochromis niloticus
Type: Journal Article
A complete diallel cross experiment was carried out with eight strains of Nile tilapia (Oreochromis niloticus). The strains represented four wild populations collected from various locations in Africa and four populations ...
Fry production of Shire River tilapia Oreochromis shiranus at two broodstock sex ratios
Type: Journal Article
Optimal sex ratio in tilapia breeding ponds depends upon stocking density. However, under certain circumstances, altering the male: female sex ratio from a more or less natural 1:1 to 1:2 or even higher has been shown to ...
