Response of Nile tilapia (Oreochromis niloticus) fry to diets containing Azolla meal
(Department of Fisheries, Bangkok, Thailand; International Center for Living Aquatic Resources Management, 1988)
Sun-dried Azolla pinnata was ground and incorporated into experimental diets at various levels (8.50, 17.00, 25.46, 34.00 and 42.45% of the diets) to replace fish meal in a control diet isonitrogenously. All feeds contained ...
Trace analysis of nitrite ion in seawater using ion chromatography
(Kyoto University, 1988)
An ion chromatographic method of separating and detecting nitrite in sea water is described. The system includes precolumn, new hydrophilic separation column, suppressor and two-valve system. Nitrite was diverted, trapped ...
Polyculture of the tiger shrimp (Penaeus monodon) with Nile tilapia (Oreochromis niloticus) in brackishwater fishponds
(1988)
A study was conducted in fifteen 500-m<sup>2</sup> ponds to determine the growth, survival and production of Penaeus monodon (Fabricius) in polyculture with Oreochromis niloticus (Linnaeus) and the extent of competition ...
Hematological and histopathological changes in Oreochromis mossambicus after exposure to the molluscicides Aquatic and Brestan
(Department of Fisheries; International Center for Living Aquatic Resources Management, 1988)
Duplicate static 96-hour bioassays were conducted to determine the median lethal concentration for Oreochromis mossambicus (LC<sub>50</sub>) of two organostannous molluscicides, commonly used in fishponds: Aquatin and ...
Problems of diseases in prawn projects.
(1988)

Cannibalism among different sizes of tilapia (Oreochromis niloticus) fry/fingerlings and the effect of natural food
(Department of Fisheries, Bangkok, Thailand; International Center for Living Aquatic Resources Management, Manila, Philippines, 1988)
Experiments were conducted in jars, tanks and aquaria to determine the occurrence of cannibalism among 7 different size groups of Nile tilapia (Oreochromis niloticus ) fry and fingerlings. Cannibalism became more intense ...
Electrophoretic studies on induced gynogenetic diploids and triploids in tilapia (Oreochromis niloticus and O. aureus)
(Department of Fisheries; International Center for Living Aquatic Resources Management. ICLARM Conference Proceedings 15, 1988)
Preliminary electrophoretic screening of laboratory maintained tilapia stocks revealed enzyme polymorphism at 3 co-dominantly inherited loci--adenosine deaminase (Ada), aminopeptidase (Ap) and malic enzyme (Me-2). Oreochromis ...
