Effect of light quality and eyestalk ablation on ovarian maturation in Penaeus monodon
Prawns were subjected to the following treatments: blue light, red light, natural light, and natural light plus unilateral eyestalk ablation. Unablated prawns under blue and natural light developed stage III ovaries; under ...
Mass production in concrete tanks of sugpo Penaeus monodon Fabricius spawners by eyestalk ablation
(Fisheries Research Society of the Philippines, 1978)
Two batches of 196 and 181 P. monodon females were ablated on one eyestalk in March and July 1977, respectively, and a control batch of 180 unablated females was stocked in July 1977. The females were stocked with males ...
Studies on the egg quality of Penaeus monodon Fabricius, based on morphology and hatching rates
(Elsevier, 1981)
Eggs of Penaeus monodon are classified into five different types on the basis of morphological criteria and hatching rates — A1 eggs undergo normal development with 58% hatching rate; A2 eggs show delayed and/or abnormal ...
Ovarian rematuration of ablated sugpo prawn Penaeus monodon Fabricius
(Institut National de la Recherche Agronomique, 1978)
Spent Penaeus monodon females were tagged around one eyestalk with numbered brass tags, stocked in a concrete tank with males, and periodically examined for ovarian rematuration over a six-month period (February to August, ...
Intensive prawn farming in the Philippines: ecological, social, and economic implications
(Springer Verlag, 1991)
The benefits of intensive farming of the giant tiger prawn Penaeus monodon in the Philippines are discussed in relation to the environmental costs. Ecological effects include mangrove conversion into ponds; use of antibiotics ...
Pond culture of sugpo, P. monodon (Fabricius)
(BFAR, 1976)
A resume is presented of the practical considerations involved in establishing a sugpo pond culture operation, as a guide to fish farmers, extension workers and others interested in producing marketable sugpo in the ...
Feeding regimes in relation to reproduction and survival of ablated Penaeus monodon
(University of the Philippines at Los Baños, 1979)
Pond-reared P. monodon were stocked in four 12-cu m flowthrough maturation tanks at 25 males and 50 females per tank; females were unilaterally ablated. The combinations of feeds for the morning and afternoon rations were ...
Runt-deformity syndrome in cultured giant tiger prawn Penaeus monodon
(Crustacean Society, 2000)
A total of 24 morphological abnormalities associated with the Runt-Deformity Syndrome (RDS) is reported for the first time in 17- to 18-mo old F<sub>3</sub> generation <i>Penaeus monodon</i> (>40 mm CL) belonging to ...
Notes on the courtship and mating behavior in Penaeus monodon Fabricius (Decapoda, Natantia)
(Brill Academic Publishers, 1979)
Courtship and mating behavior in the sugpo or giant tiger prawn, Penaeus monodon Fabricius, are described. These are divided into three phases: parallel swimming of male and female; male turns ventral side up to female; ...
Light color and ovarian maturation in unablated and ablated giant tiger prawn Penaeus monodon (Fabricius)
(Elsevier, 1992)
The effect of light color (green, blue and white fluorescent lights, with natural light as a control) on maturation in intact and eyestalk-ablated Penaeus monodon was tested in 12-m<sup>3</sup> broodstock tanks. Size and ...
