Interaction of the midgut gland and the ovary in vitellogenesis and consequences for the breeding success: a comparison of unablated and ablated spawners of Penaeus monodon
(European Aquaculture Society, 1989)
The midgut glands and ovaries of unablated and ablated females of Penaeus monodon were examined before and after spawning by light and electron microscopy to elucidate the role of the midgut gland during vitellogenesis. ...
Growth and external reproductive parameters in pond-reared Penaeus monodon.
(University of the Philippines, Marine Science Institute, 1994)
Pond-reared Penaeus monodon males and females were sampled regularly over a 4 month period of length and weight measurments to the body and external reproductive organs; joining of the petasmata and the presence of sperm ...
Osmoregulation in Penaeus monodon: effects of molting and external salinity.
The effect of molting on osmotic, chloride, calcium and total protein concentrations in the hemolymph of the shrimp Penaeus monodon was investigated. Regardless of medium salinity, tissue water as well as osmotic and ...
Review of SEAFDEC/AQD fish nutrition and feed development research.
Research on fish nutrition and feed development at SEAFDEC Aquaculture Department has focused on three major areas: nutrient requirements and their interrelationships, digestive enzymes and digestibility, and practical ...
Shrimp diseases in the Philippines: a historical perspective of research, training and development.
(Department of Marine Biology, Ocean University of Qingdao, 1998)
Pioneering research on shrimp diseases in the Philippines was spearheaded at the Aquaculture Department of the Southeast Asian Fisheries Development Center at Tigbauan, Iloilo in 1975. Investigations initially covered ...
Shrimp aquaculture: the Philippine experience
(Australian Centre for International Agricultural Research, 1999)
An overview is presented of the shrimp farming industry in the Philippines, noting that it was established as brackish-water aquaculture as early as 1521, although it took until the 1970s to take off, blooming during the ...
Studies on the sources of luminescent Vibrio harveyi in Penaeus monodon hatcheries
(Asian Fisheries Society, Fish Health Section, 1992)
One of the major problems in the otherwise highly successful Penaeus monodon hatchery industry in the Philippines is the occurrence of luminescent bacterial disease due to Vibrio harveyi. The possible sources of the bacteria ...
The effect of different feed combinations using chicken egg yolk in Penaeus monodon larval rearing
(Brigham Young University Hawaii Campus, 1983)
Qualitative and quantitative comparison of bacterial flora associated with hatchery-reared and wild-caught shrimp postlarvae
Because of high mortality recorded in pond-reared shrimps due to luminescent vibriosis infection, a study was conducted to determine if postlarvae (PLs) could be major sources of luminescent bacteria (LB). Batches of ...
Will microbial manipulation sustain the ecological balance in shrimp (Penaeus monodon) hatcheries?
(National Center for Genetic Engineering and Biotechnology, 1998)
A shift in preferred methods employed to contain bacterial diseases in the hatchery phase of shrimp culture has resulted largely from the unsuccessful control by and deleterious effects of chemotherapy. Manipulation of ...
