Biology and farming of the green mussel Mytilus smaragdinus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)Biological investigations were carried out in Sapian Bay, Capiz from November 1975 to December 1976 with samplings conducted fortnightly. Histological studies on the gonad reveal a high percentage of ripe and spent females ... -
Bacteria from seawater used in Penaeus monodon larval cultures
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)Bacteria in the seawater used in P. monodon hatchery operations were isolated on Bachmann's agar. The total plate counts in 25 isolations ranged from 1.0 - 5.0 x 102 to 5.1 -10.0 x 105 cells per ml. ... -
Reduction in Chaetoceros populations by furanace
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)One of the most promising prophylactic agents being tested to control Penaeus monodon larval diseases is furanace (6-hydroxymethyl-2 2(5-nitro-2-furyl) vinyl pyridine). To evaluate further its suitability as a chemotherapeutic ... -
Effects of furanace on Brachionus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)Tiger prawn P.monodon) larvae utilize Brachionus a rotifer, as food in the Zoea 3 and mysis stages when they change from an herbivorous to an omnivorous diet. The present work aims to show the effects of furanace on the ... -
Preliminary biological evaluation of some formulated feeds for P. monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)Rice bran is widely used by fish farmers as supplementary feed while soybean cake is used both as feed and as fertilizer in fishponds. Both fish meal and shrimp head have been found acceptable as feed ingredients. However, ... -
Preliminary chemical and physical evaluation of some formulated feeds for P. monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)The culture of Penaeus monodon has explicitly defined the need for diet formulations or supplementary feeds that would promote optimum growth and survival of the animal. A total of 28 feed combinations were developed for ... -
The effect of various protein levels on the growth and survival rates of Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)Postlarvae of tiger prawns, P. monodon , were fed with various protein levels of 0; 30; 40 and 50%, fish meal and rice bran were combined and pelletized for 16 wks. Prawns used had an average mean length of 1.2 mm and an ... -
Tolerance of Penaeus monodon larvae to cupric sulfate added in bath
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)Copper is used to deter the growth of bacterial, fungal and protozoan disease organism in fishes. Zoeae (Z1), myses (M1) and postlarvae (P1) were exposed to copper sulfate at concentrations ... -
Effect of furanace on the development of larval stages of Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)Zoea 2 (Z2), Mysis 1 (M1) and Postlarva 1 (P1) of P. monodon artificially spawned in closed-system concrete hatchery tanks were bioassayed for their tolerance to the antibiotic furanace. ... -
A suctorean parasite of Penaeus monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)A new disease caused by a suctorean has been observed in tank-spawned and reared P. monodon larvae. Identification of the etiologic agent pointed to Ephelota gemmipara R. Hertwig, a species commonly found to inhabit hydroid ... -
Identification and culture of common diatoms as possible feed for Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)Diatoms were collected from Buyuan Bay, and from the hatchery tanks at Tigbauan, to determine the commonly occurring species, the feasibility of culturing these species, and the potential of these selected species as food ... -
A simple method of tagging prawns
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)The recognition of individual animals is crucial to many aspects of research. Prawns (Penaeus monodon) present unique difficulties in this respect since they molt regularly. Thus, almost all tagging and marking methods ... -
An assessment of the coastal resources of Ibajay and Tangalan, Aklan: Implications for management
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2001)This report describes the present state of marine resources in several coastal barangays of Ibajay and Tangalan, Aklan (Philippines). Field data were obtained from rapid surveys conducted from July to September 1998. ... -

(Aquaculture Department, Southeast Asian Fisheries Development Center, 1975)The 1974 report describes the development of project sites at Tigbauan and Leganes, where new ponds and labs have been established. The facilities of these labs include covered and open ponds, wet and field labs, a food ... -
First annual report of the Aquaculture Department of the Southeast Asian Fisheries Development Center (SEAFDEC) for the fiscal year ending December 31, 1973
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1974)An illustrated account is presented, covering background (establishment of the department), plan of operation (functions; activities), project site development (Leganes Station, Tigbauan Station, construction of buildings, ... -
