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 ...
The effect of stunting on growth, survival, and net production of milkfish (Chanos chanos Forsskal)
(Elsevier, 1988)
The seasonal abundance of milkfish fry in the Philippines has led to the practice of buying a sufficient supply during the peak season to compensate for the shortage during slack periods. Fry that are not immediately grown ...
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 ...
Comparison of the silo and broadcast methods of applying organic fertilizer in milkfish, Chanos chanos (Forsskal), ponds
(Elsevier, 1988)
The efficacy of the silo and broadcast methods of applying organic fertilizers in ponds for the production of pond-floor, microbenthic biological complex, a natural food source known as lablab, was tested in 1-ha ponds, ...
Transition from endogenous to exogenous nutrition sources in larval rabbitfish Siganus guttatus
(Japanese Society of Fisheries Science, 1988)
The early larval development of Siganus guttatus was studied with emphasis on the transition from endogenous to exogenous feeding. Three rearing trials were conducted as follows: 1) rearing in a 5 ton concrete tank at ...
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 ...
The effect of dietary protein-energy levels on growth and metabolism of milkfish (Chanos chanos Forsskal)
(Elsevier, 1988)
<ol><li>Groups of milkfish juveniles (mean weight, 2.8 g) were fed diets containing white fishmeal and gelatin with varying protein-energy to total metabolizable energy (PE:TME) ratios.</li><li>Amino acids were incorporated ...
Critical factors influencing survival and hatching of milkfish (Chanos chanos Forsskal) eggs during simulated transport
(Elsevier, 1988)
The effects of loading density, length of transit time, temperature and salinity on milkfish (Chanos chanos Forsskal) eggs during simulated transport were examined. Rocking motion approximating conditions of transport of ...
Cage culture of Oreochromis aureus and Oreochromis niloticus hybrids in Laguna Lake, Philippines
(Taylor & Francis, 1988)
A reciprocal cross of male Oreochromis aureus and female Oreochromis niloticus were made to produce the hybrids stocked in cages in Laguna Lake, Philippines with and without feeding. The growth rates of the hybrids from ...
Problems of diseases in prawn projects.
(1988)
A major factor that influeces the success of production in the prawn industry is the occurrence of disease. Early stage of prawn in hatchery-nursery systems are subject to attacks of viruses, bacteria, fungi and protozoan ...
