Effect of different stocking densities on survival and growth of sugpo (Penaeus monodon Fabricius) in a milkfish-rearing pond
(STII-DOST, 1976)
Employing a direct stocking monoculture method, postlarval P. monodon were stocked in 8 compartments of a shallow milkfish rearing pond at densities of 1, 2, 3 and 4/sq m with replicates. Feeding was exclusively natural ...
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
(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
(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 ...
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 ...
Distribution pattern of shrimps and fish among Avicennia and Rhizophora microhabitats in the Pagbilao mangroves, Philippines
(Elsevier, 1999)
For sustainable management of mangrove ecosystems, there is a pressing need to increase our knowledge of fish and invertebrates associated with this system. This study sampled microhabitats (89–258 m<sup>2</sup>) ...
Survival rates of different Penaeus monodon Fabricius postlarval stages
(National Science Development Board, 1976)
Four different postlarval stages (P<sub>11</sub>, P<sub>15</sub> , P<sub>21</sub>, and P<sub>25</sub>) of P. monodon were stocked in suspension nets at the rate of 200 fry/sq m with 3 nets for each postlarval stage. Pond ...
Effect of tagging on maturation and survival of ablated Penaeus monodon in painted and unpainted tanks
(San Carlos Publications, University of San Carlos, 1989)
A study was conducted to determine the effects of tags and tank color on reproductive performance and survival of pond-reared Penaeus monodon after eyestalk ablation. In 1986, the best over-all reproductive performance was ...
Nature's subsidies to shrimp and salmon farming
(American Association for the Advancement of Science, 1998)
Although many fisheries stocks have declined precipitously throughout the world, fish farming--and especially shrimp and salmon farming--has boomed. The increasingly large scale of these enterprises is now having unforeseen ...
Gill structure, anatomy and habitat of Anodontia edentula: Evidence of endosymbiosis
(National Shellfisheries Association, 2001)
Surveys and interviews were conducted to determine sources and habitat of Anodontia edentula. Results showed that they inhabit muddy substrate of mangrove areas or the adjacent mudflats, burying at 20-60 cm deep in the ...
Illuminating the need for ecological knowledge in economic valuation of mangroves under different management regimes - a critique
(Elsevier, 2000)
This is a commentary on a paper by Gilbert and Janssen (Gilbert, A.J., Janssen, R., 1998. Ecol. Econ. 25, 323–346) that deals with valuation of management alternatives for the Pagbilao mangroves, Philippines. Our main ...
