Maturation and induced spawning of the mangrove red snapper (Lutjanus argentimaculatus) reared in a floating net cage in the Philippines
(International Center for Living Aquatic Resources Management (ICLARM), 1996)Wild-caught mangrove red snapper (Lutjanus argentimaculatus) were reared in a floating net cage at SEAFDEC/AQD's Igang Marine Substation at Guimaras Island, Central Philippines. In 1993, monthly samplings and induced ... -
Use of metaldehyde as molluscicide in milkfish ponds
(British Crop Protection Council, 1996)METAR metaldehyde formulations were tested under laboratory and faild conditions againts brackishwater pond snails (certhium so.). Under laboratory conditions the LC50 and LC99 3 days after ... -

Bacterial diseases of penaeid shrimps: An Asian view
(Fish Health Section, Asian Fisheries Society, 1995)In the past 5 Yr, bacterial diseases have become limiting factors in penaeid culture systems, their effects becoming directly proportional to the growth of the industry in terms of severity and imoact. Although eight ... -
Siderophore detection among bacteria associated with the epizootic ulcerative syndrome (EUS)
(Fish Health Section, Asian Fisheries Society, 1995)Sixteen isolates of Aeromonas hydrophila andone isolate each of Aeromonas sp. n., Aquaspirillum sp., Pseudomonas sp., and Streptococcus sp., isolated from normal, apparently normal and epizootic ulcerative syndrome ... -
Recent technical developments in aquaculture and training needs
(Asian Productivity Organization, 1995)This paper attempts to present recent developments and techniques in breeding, seed production, genetics, feed development, and fish health management. Most of the innovative findings come from work done on well-studied ... -
Improved hatchery rearing techniques for the Asian catfish, Clarias macrocephalus (Gunther)
(European Aquaculture Society, 1995)The Asian catfish, Clarias macrocephalus, is a popular freshwater foodfish in the Philippines. However, grow-out farming of this species is hampered by the lack of juveniles for stocking. A series of experiments on zooplankton ... -
Experimental transmission of epizootic ulcerative syndrome (EUS) in snakehead, Ophicephalus striatus
(Fish Health Section, Asian Fisheries Society, 1995)Two separate experiments on transmission of epizootic ulcerative syndrome (EUS) to naive snakehead (Ophicephalus striatus) by cohabitation with EUS-positive snakehead in EUS-enzootic environment and exposure to EUS-enzootic ... -
Reproductive performance of wild-caught mangrove red snapper, Lutjanus argentimaculatus
(European Aquaculture Society, 1995)Interest in the culture of snappers, belonging to the family Lutjanidae, is increasing in Southeast Asia due to their relatively high market price. However, the fry needed for culture still comes exclusively from the wild. ... -
Supplementation of grouper (Epinephelus coioides) weaning diet with different sources of phospholipids
(European Aquaculture Society, 2001)In a rapidly growing fish, phospholipid requirements are high due to rapid membrane development. At an early stage, larvae cannot synthesize large amounts of phospholipids for membrane development, which should therefore ... -
LHRHa and pimozide-induced breeding in the catfish, Clarias macrocephalus (Gunther).
(1994)Clarias macrocephalus is endemaic yet dwinding freshwater foodfish in the Philippines. Induced breeding protocol was developed after a series of studies which determined the appropriate egg size, proper time of stripping ... -
The ecological impact of tilapia cage culture in Sampaloc Lake, Philippines
(Asian Fisheries Society, 1994)Sampaloc lake showed imminent biological death as a consequence of intensive tilapia farming in floating net cages. The progressive disappearance of dissolved oxygen in the entire water column may be an irreversible trend ... -
Evaluation of free essential amino acid in muscle of Nile tilapia (Oreochromis niloticus), as a basis of amino acid requirement for growth.
(Asian Fisheries Society, 1994)The free essential amino acid levels in muscle of young Nile tilapia (Oreochromis niloticus) after feeding graded amounts of a corresponding test amino acid were measured in 9 separate experiments to determine if free amino ... -
Conflict in small-scale fisheries: a case study of Malalison Island, Philippines
(Asian Fisheries Society, 1994)This paper provides a framework of conflict in small-scale fisheries and presents a case study of an island community in central Philippines. The following sources of conflict were identified: destruction of fishing gears, ... -
Growth and external reproductive parameters in pond-reared Penaeus monodon
(Marine Science Institute, University of the Philippines, 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 ... -
Occurrence of aberrant spermatids in the freshwater sculpin, Cottus nozawae Snyder
(Asian Fisheries Society, 1994)Light and electron microscopic investigation were conducted on the spermatogenic cell in the testis of the freshwater sculpin, Cottus nozawae. Light microscopic examination showed that two types of spermatids, normal and ... -

Evaluation of fish protein concentrate and lactic yeast as protein sources for shrimp feeds
(Asian Fisheries Society, 1994)Protein sources, hydrolyzed fish protein concentrate and plasmolyzed lactic yeast, were used to partially replace fish meal and soybean meal, respectively, in a basal diet (diet 1) at these levels; 5% fish protein concentrate ... -
Larval intervals of the sea bass, Lates calcarifer, based on the development of swimming and feeding functions.
(Asian Fisheries Society, 1994)Developmental sequences of characters concerned in swimming and feeding function were examined on laboratory-reared seabass larvae. Based on a scheme of development events constructed in this study, the early life hisory ...
