Timing of Supplemental Feeding for Tilapia Production
(Blackwell Publishing Ltd, 1996-12)
The staged addition of feed to fertilized fish ponds was evaluated by adding fertilizers to 15 ponds stocked with Nile tilapia Oreochromis niloticus , then adding feed at half ad libitum rates once fish in the ponds reached ...
Multiple Basins Of Attraction In A Tropical Forest: Evidence For Nonequilibrium Community Structure
(Ecological Society of AmericaWiley Periodicals, Inc., 2004-02)
The effects of water exchange rate and density on yield of the walking catfish, Clarias fuscus
(Elsevier, 1989-06)
High stocking densities (600 fish/m3) of walking catfish resulted in slightly higher mortality rate, no difference in growth rate, and a much higher yield than low density stocking (300 fish/m3). Water flow rate (10, 5, ...

The partial molar volume, thermal expansivity, and compressibility of H 2 O in NaAlSi 3 O 8 liquid: new measurements and an internally consistent model
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-10)
The molar volumes of 19 hydrous albitic liquids (1.9 to 6.1 wt% H 2 O total ) were determined at one bar and 505–765 K. These volume data were derived from density measurements on hydrous glasses at 298 K, followed by ...
The Effects of Fertilization and Water Management on Growth and Production of Nile Tilapia in Deep Ponds During the Dry Season
(Blackwell Publishing Ltd, 1998-12)
Fertilization guidelines developed for shallow ponds (1 m) with controlled depths were tested in deeper (2.5 m) ponds to determine effectiveness of these guidelines for culture of Nile tilapia Oreochromis niloticus . Twelve ...
Models of coupled population oscillators using 1-D maps
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-08)
Coupled population oscillators are investigated with the use of coupled logistic maps. Two forms of coupling are employed, reproductive and density. Three biologically distinct situations are investigated: populations ...
