Evaluation of organic and inorganic fertilizers in brackishwater milkfish ponds
The study was conducted in twelve 144-m<sup>2</sup> ponds to evaluate the effect of different organic and inorganic fertilizers on the growth, survival, gross production, and profitability of marketable milkfish. The ...
Changes in shrimp feed quality and effects on growth and survival of Penaeus monodon juveniles
(Elsevier, 1997)
Five practical shrimp diets were formulated to contain 1, 10, 20, 50, and 100 g tetraethoxypropane (TEP) kg<sup>−1</sup> diet. A diet with no added TEP served as the control. Diets were fed to Penaeus monodon (average ...
Analysis of nitrite in aqueous solutions containing concentrated matrix ions using an octadecyl-poly(vinyl alcohol) gel microbore column and an electrochemical detector
(Dr. Alfred Huethig Publishers, 1991)
The importance of the analysis of low level nitrite concentrations in aqueous samples is increasing in various fields such as environmental, food, and aquaculture chemistry. Recent progress in ion chromatography paved the ...
Effects of antioxidants on feed quality and growth of Penaeus monodon juveniles
(Wiley-Blackwell, 1992)
Four practical diets were formulated to contain 0.05%, of the following antioxidants: butylated hydroxytoluene (BHT), butylated hydroxy anisole (BHA), propyl gallate (PG) or ethoxyquin (ETHQ). A fifth diet, with no added ...
Chicken manure, rice hulls, and sugar-mill wastes as potential organic fertilizers in shrimp (Penaeus monodon Fabricius) ponds
(Elsevier, 1992)
Shrimp (Penaeus monodon Fabricius) were cultured (3000 juveniles/ha) in 50-m<sup>2</sup> earthen ponds fertilized with composted agricultural and industrial wastes at a basal application rate of 2 ton/ha. The following ...
The macronutrient composition of natural food organisms mass cultured as larval feed for fish and prawns
(Society of Israeli Aquaculture and Marine Biotechnology, 1990)
The macronutrient composition of natural food organisms that are mass cultured as feed for the larval stages of fish and prawns in the SEAFDEC Aquaculture Department was determined by chemical analysis. The food organisms ...
Ion chromatography of inorganic anions in brine samples
(Oxford University Press, 1989)
An ion chromatographic method for separating and detecting anions in brine samples is described. Nitrite, bromide, nitrate, and sulfate ions in brine samples are well separated when chloride ion concentration in the sample ...
Influence of stocking density and fertilization regime on growth, survival and gross production of Penaeus monodon Fabricius in brackishwater ponds
(Society of Israeli Aquaculture and Marine Biotechnology, 1991)
Twelve 0.1 ha earthen ponds were stocked at 3,500 or 7,000/ha with 1-month old nursery reared Penaeus monodon Fabricius (1.73 g). Fertilizer treatments were 125 kg chicken manure plus 4.1 kg diammonium phosphate (18-46-0) ...
Ion chromatography of nitrite, bromide and nitrate ions in brine samples using a chloride-form anion-exchange resin column
(Elsevier, 1990)
In aquaculture research, maintenance of water culture quality is of great importance. Recent improvement in fishpond management and fish culture systems, such as intensive feeding and fertilization, have created complex ...
Performance of recirculating systems for prawn hatchery and broodstock maturation tanks
(Elsevier, 1991)
The potential use of recirculating systems with facilities for waste removal for prawn (Penaeus monodon) hatchery and broodstock maturation tanks was investigated. Recirculating systems evaluated for larval culture tanks ...
