Use of hormones in breeding cultivated warm-water fishes with special reference to milkfish, Chanos chanos (Forskal)
(Fisheries Research Society of the Philippines, 1978)The role of hormones in the controlled reproduction of a few test fishes is well documented. However, information on the mechanisms of endocrine regulation of ovulation in cultivated warm-water fishes is very meagre. ... -
Decapsulation of Artemia cysts: A simple technique for the improvement of the use of brine shrimp in aquaculture
(Elsevier, 1977)Although it is a common practice in different disciplines of fundamental research on the brine shrimp, and despite the very interesting applications that it offers for the use of Artemia in aquaculture, the "decapsulation" ... -
Variation in the vertebral number of the milkfish Chanos chanos, collected from various localities
(The Faculty of Fisheries, Nagasaki University, 1977)A total of 2497 milkfish fry were collected in 1976 from nine localities in six countries, viz. India, Thailand, Indonesia, Philippines, Taiwan and Tahiti. Vertebra counts ranged from 40 to 45. The general trend of ... -
Induction of maturity and spawning in Penaeus monodon Fabricius, 1798, by unilateral eyestalk ablation (Decapoda, Natantia)
(Brill Academic Publishers, 1976)Preliminary experiments carried out at the Aquaculture Department of the Southeast Asian Fisheries Development Centre in the Philippines have achieved success in the rearing of viable F1 postlarvae of Penaeus ... -
A simple method of tagging prawns
(University of the Philippines, 1976)The recognition of individual animals is crucial to many aspects of research. Prawns present unique difficulties in this respect since they molt regularly. Thus almost all tagging and marking methods developed for prawns ... -
Pond culture of sugpo, P. monodon (Fabricius)
(BFAR, 1976)A resume is presented of the practical considerations involved in establishing a sugpo pond culture operation, as a guide to fish farmers, extension workers and others interested in producing marketable sugpo in the ... -
Notes on the external sex characters of Chanos chanos (Forskal) spawners
(Fisheries Research Society of the Philippines, 1976)In the present study, no visible differences between the sexes of C. chanos with reference to external features such as colouration, shape of head, snout and operculum, presence of tubercles or nasal pores, length, size ... -
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 ... -
Survival rates of different Penaeus monodon Fabricius postlarval stages
(National Science Development Board, 1976)Four different postlarval stages (P11, P15 , P21, and P25) of P. monodon were stocked in suspension nets at the rate of 200 fry/sq m with 3 nets for each postlarval stage. Pond ... -

(Springer-Verlag, 1978)The vertical distribution of euthecosomatous pteropods in the upper 100 m of the Hilutangan Channel, Cebu, The Philippines was studied, based on 126 samples, comprising 47, 282 individuals. Thirty-min horizontal plankton ... -
Population biology of the Japanese little-neck clam, Tapes philippinarum, in Kaneohe Bay, Oahu, Hawaiian Islands
(University of Hawaii Press, 1977)The Japanese little-neck clam, Tapes philippinarum, an introduced species in Kaneohe Bay, Oahu, Hawaiian Islands, has a thriving population only in a U5-hectare mud flat after heavy fishing triggered depletion in six other ... -
The larval stages of benizuwai-gani, Chinoecetes japonicus Rathbun reared in the laboratory
(The Japanese Society of Fisheries Science, 1976)This study deals with the larval stages of C. japonicus, and with the comparison with those of Zuwaigani, C. opilio. There are 2 zoneae and 1 megalopa. The larval stages of C. japonicus are morphologically similar to those ... -
Early larval development of the seabass Lates calcarifer with emphasis on the transition of energy sources
(Japanese Society of Fisheries Science, 1986)The early growth, yolk and oil globule resorption, early morphological and behavioral de-velopment, and initial feeding of hatchery-raised Lates calcarifer were studied. Based on the developmental events and the energy the ... -
The response of Penaeus monodon juveniles to varying protein/energy ratios in test diets
(Elsevier, 1986)Two sets of factorial experiments were conducted for 8 weeks to determine the response of Penaeus monodon juveniles (average weights = 0.60 ± 0.16 g and 0.80 ± 0.05 g) to diets containing various protein/energy ratios. The ... -
Spontaneous maturation and spawning of milkfish in floating net cages
(Elsevier, 1986)Milkfish (Chanos chanos Forsskal) reared from wild-caught fry and from hatchery-bred fry matured at 3.5-5.5 years (2.3-4.9 kg). Maturation and spawning of the hatcherybred fish marks the first time the milkfish life-cycle ... -
The milkfish seed resources survey in Sri Lanka: Status, problems and recommendations

Studies on the chronic soft-shell syndrome in the tiger prawn, Penaeus monodon Fabricius, from brackishwater ponds
(Elsevier, 1986)Prawn culture is becoming more widespread in the Philippines. In recent years, prawn production in brackishwater ponds has been adversely affected by a chronic soft-shell syndrome. A field survey of prawn ponds in the ... -
