Effect of different stocking combinations on growth, production and survival of milkfish (Chanos chanos Forskal) and prawn (Penaeus monodon Fabricius) in polyculture in brackishwater ponds
; Primavera, Jurgenne 
(Elsevier, 1981)
(Elsevier, 1981)
Milkfish (Chanos chanos) and prawn (Penaeus monodon) were stocked in 500 m2 earthen ponds from 12 November 1978 to 15 March 1979 at the following combinations: 2000 milkfish fingerlings per ha (treatment I); 2000 milkfish ...

A comparison of two prawn (Penaeus monodon ) brood stock systems—land–based tanks and marine pens
Primavera, Jurgenne ; (World Aquaculture Society, 1981)
; (World Aquaculture Society, 1981)
The paper compares two prawn (Penaeus monodon) brood stock systems—land-based tanks and marine offshore pens. Construction costs and annual maintenance and operating costs total US\$1,430 and \$2,550 for the tank and \$1,500 ...

An assessment of algal growth in net cages in Laguna Lake
(Fisheries Research Society of the Philippines, 1981)
Quantitative determination of the algal population, in terms of cells/ml and biomass/ml, was conducted during the first month of growing P. monodon postlarvae in Laguna Lake. Algae were sampled from each side of net cages ...

Pigmentation pattern in the early developmental stages of milkfish (Chanos chanos): A key for larval identification.
(Fisheries Research Society of the Philippines, 1981)
Pigmentation patterns are presented for 5 - 20 day old milkfish (Chanos chanos) and are discussed in terms of their use in larval identification.

Feeding behavior and food preference of Penaeus monodon Fabricius with scrap Tilapia mossambica
(Fisheries Research Society of the Philippines, 1981)
The time of day during which P. monodon feeds at different depth levels in earthen ponds, and its preference for three types of tilapia feeds (dry, fresh and fermented) were determined. It was observed that P. monodon ...

Lactate dehydrogenase isozyme patterns during the development of milkfish, (Chanos chanos (Forskal))
(University of the Philippines at Los Baños, 1981)
Polyacrylamide disc gel electrophoresis was done to determine the lactate dehydrogenase (LDH) isozyme patterns for fry (5-3 mg), fingerling (6-12 g), pond-size (150-250 g) and adult (6-9 kg) milkfish. The patterns were ...

Acute toxicity of un-ionized ammonia to milkfish (Chanos chanos) fingerlings
(Fisheries Research Society of the Philippines, 1981)
The acute toxicity of un-ionized ammonia to milkfish (Chanos chanos) fingerlings was determined using a static bioassay system. The 24-, 48-, 72-, and 96-hr LC<sub>50</sub> values were calculated at 25.74 ppm NH<sub>3</sub>-N ...

Survival, growth and production of Penaeus monodon Fabricius at different stocking densities in earthen ponds with flow-through system and supplemental feeding.
(Fisheries Research Society of the Philippines, 1981)
Penaeus monodon juveniles (P<sub>53</sub>-P<sub>54</sub>, 0.45 g) were stocked in 200 m<sup>2</sup> earthen ponds with water exchange rate of 5-10% daily, and reared for 3.5 months. Stocking density levels of 2.5, 5.0, 10 ...

Identification of postlarvae of the genus Penaeus appearing in shore waters
(Carcinological Society of Japan, 1981)
Diagnostic features for the identification of postlarval Penaeus found in the shore waters of the Philippines are described and categorized based on specimens caught from the wild and those hatched and reared in the ...
