Ovarian rematuration of ablated sugpo prawn Penaeus monodon Fabricius
- Annales de biologie animale, biochimie, biophysique, 1978 - Institut National de la Recherche Agronomique
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
- AMBIO: A Journal of the Human Environment, 1991 - Springer Verlag
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 ...
Artificial substratum consisting of poly-β-hydroxybutyrate-based biodegradable plastic improved the survival and overall performance of postlarval tiger shrimp Penaeus monodon
- Aquaculture Research, 2019 - Wiley
The use of artificial substratum consisting of poly‐β‐hydroxybutyrate (PHB)‐based biodegradable plastic for penaeid shrimp culture was investigated in the present study. The survival of postlarval tiger shrimp Penaeus ...
Studies on the egg quality of Penaeus monodon Fabricius, based on morphology and hatching rates
- Aquaculture, 1981 - Elsevier
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 ...
Contribution of natural food and supplemental feed to the gut content of Penaeus monodon Fabricius in a semi-intensive pond system in the Philippines
- Aquaculture, 1998 - Elsevier
Juvenile Penaeus monodon were stocked in grow-out ponds and fed a compound diet at high rates for 19 weeks under semi-intensive conditions. At three stages of the rearing period (weeks 6, 11 and 16), the gut content of the ...
Economic assessment of commercial hatchery production of milkfish (Chanos chanos Forsskal) fry
- Journal of Applied Ichthyology, 1999 - John Wiley and Sons
The economic viabilities of two types of commercial hatchery milkfish (Chanos chanos) fry operations were assessed and compared. Based on the actual cost of input, the physical facilities, and the potential production ...
Feeding regimes in relation to reproduction and survival of ablated Penaeus monodon
- Kalikasan, The Philippine Journal of Biology, 1979 - University of the Philippines at Los Baños
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 ...
Effect of light quality and eyestalk ablation on ovarian maturation in Penaeus monodon
- Kalikasan, The Philippine Journal of Biology, 1981 - University of the Philippines Los Baños
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 ...
Effect of fatty acid composition of broodstock diet on tissue fatty acid patterns and egg fertilization and hatching in pond-reared Penaeus monodon
- Asian Fisheries Science, 1989 - Asian Fisheries Society
The effect of dietary fatty acid composition on tissue fatty acid patterns and Penaeus monodon was evaluated with the use of 3 practical diets. Diets were formulated to contain the same basal components but with various ...
Mangroves as nurseries: Shrimp populations in mangrove and non-mangrove habitats
- Estuarine, Coastal and Shelf Science, 1998 - Elsevier
A total of 4845 penaeids belonging to nine species—Metapenaeus anchistus, M. ensis, M. moyebi, M. philippinensis, Penaeus merguiensis, P. monodon, P. semisulcatus, P. latisulcatus and Metapenaeopsis palmensis—were collected ...
