Ipil-ipil (Leucaena leucocephala) leaves as a plant protein source in prawn diets
- SEAFDEC Aquaculture Department Quarterly Research Report, 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
Penaeus monodon juveniles were fed diets containing fish meal, shrimp head meal and ipil-ipil leaves soaked and unsoaked, local and peruvian varieties. Mean weight gain at the end of 8 wk was significantly highest among ...

Studies on the egg quality of Penaeus monodon Fabricius based on morphology and hatching rates
- SEAFDEC Aquaculture Department Quarterly Research Report, 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
Eggs of P. monodon are classified into 5 different types on the basis of morphological criteria and hatching rates: A1 eggs, which undergo normal development with 58% hatching rate; A2 eggs, which ...

Effect of substrate types on fecundity and nauplii production of ablated Penaeus monodon Fabricius
- SEAFDEC Aquaculture Department Quarterly Research Report, 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
Experiments were undertaken to assess the survival, spawning, fecundity and nauplii production of ablated P. monodon females reared in flow-through broodstock tanks with white coralline and black sand substrate for 62 days. ...

In-vitro effect of fungicides on hyphal growth and sporogenesis of Lagenidium sp. isolated from Penaeus monodon larvae and Scylla serrata eggs
- SEAFDEC Aquaculture Department Quarterly Research Report, 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
The sensitivity of Lagenidium, isolated from Penaeus monodon, Scylla serrata , to 34 antimycotics was determined. Effects on the development of vesicles, zoospores and mycelial growth were evaluated. Although mycoidal ...

Survival, growth and production of Penaeus monodon at different stocking densities in earthen ponds with flow-through system and supplementary feeding
- SEAFDEC Aquaculture Department Quarterly Research Report, 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
The survival, growth and production of Penaeus monodon in earthen ponds were observed. A significant effect of stocking density on the survival rate of prawns was observed. The final average weight obtained varied inversly ...

Polyculture of milkfish (Chanos chanos) and tiger prawn (Penaeus monodon Fab.) with and without supplemental feeding
- SEAFDEC Aquaculture Department Quarterly Research Report, 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
Twelve 1,000 m2 earthen ponds were used to compare the growth rates, survival and production of milkfish (Chanos chanos) and prawn (Penaeus monodon) in monoculture and polyculture systems in shallow brackishwater ...
Article
Feeding behavior and food preference of Penaeus monodon Fabricius with scrap tilapia
- SEAFDEC Aquaculture Department Quarterly Research Report, 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
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 ...

Evaluation of milkfish (Chanos chanos Forskal) and prawn (Penaeus monodon Fabricius) in polyculture systems
- SEAFDEC Aquaculture Department Quarterly Research Report, 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
The growth, survival and profitability of C. chanos and P. monodon grown in 5 different combinations for 100 days in 500m2 brackish water ponds were assessed. Differences in the growth and production of prawns ...

Growth and survival of Penaeus monodon Fabricius zoeae on different diatom feeds
- SEAFDEC Aquaculture Department Quarterly Research Report, 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
A study was undertaken to determine the most suitable food for Penaeus monodon zoea out of mixed diatoms, Skeletonema costatum, Chaetoceros calcitrans and C. gracilis. Results indicate that mixed diatoms and C. gracilis ...
