A new sparoid fish, Gymnocranius elongatus, from the southern South China Sea
(The Ichthyological Society of Japan, 1973)A new sparoid fish, Gymnocranius elongatus is reported from the southern South China Sea and the sea off the coast of the northwestern Australia.The fish described by Bleeker (1877) under the name of G. griseus is considered ... -
A rational sampling method for estimation of demersal fish abundance
(Japanese Society of Fisheries Science, 1973)Two contradictory requirements are anticipated in trawling experimentally a wide unexploited area with the purpose of estimating fish abundance. The one is to take large enough sample to analyse quantitatively in a locality, ... -
On Pristipomoides multidens and P. typus (Family Lutjanidae)
(The Ichthyological Society of Japan, 1975)Pristipomoides multidens (Day), usually considered a synonym of P. typus Bleeker, is shown to be a valid species of lutjanid fish. Existence of yellow bands on snout and cheek, transverse vermiculations on interorbital ... -
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 ... -
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 ... -
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 ... -
Larvae of decapod crustacea of the Philippines - I. The zoeal stages of a swimming crab, Charybdis cruciata (Herbst) reared in the laboratory
(The Japanese Society of Scientific Fisheries, 1976)Six zoeal stages of Charybdis cruciata (Herbst) which are reared in the laboratory, are described. The zoea has a rostral, a dorsal and a pair of laterial spines. There are a pair of lateral hooks on the 2nd and 3rd abdominal ... -
Note: larvae of decapod crustacea of the Philippines. II. Laboratory-hatched first zoea of box crab
(College of Agriculture and Central Experiment Station, University of the Philippines at Los Baños, 1976)This is the first report in the world on the characters of the first zoea of Calappa philargius under laboratory conditions. The zoea has a rostral, a dorsal and a pair of lateral spines on the carapace. The average length ... -
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 ... -
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 ... -
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 ... -
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 ... -
A preliminary report on the fauna of decapod crustacea in the mangrove and estuarine areas of Batan Bay, Panay Island, Philippines
(Los Baños, Laguna, Philippines: Philippine Council for Agricultural and Resources Research, 1977)In the Philippines, the total mangrove site for aquaculture development and others is about 576,000 hectares which constitute only 1.9 percent of the country's land resources. There are at present about 176,000 hectares ... -
The layout, construction and management of brackishwater fishponds in the Philippines
(South China Sea Fisheries Development and Coordinating Programme, 1977)With the advent of new research and studies into aquaculture practices there is a need to improve the size and shape of brackishwater ponds in the Philippines and to make their management more efficient. This article ... -
Engineering aspects and problems in the design and construction of fishpens and fish cages in Laguna Lake, Philippines
(South China Sea Fisheries Development and Coordinating Programme, 1977)The profitability of the fishpen industry in Laguna de Bay cannot be over-emphasized. However, a good engineering design must be prepared, in addition to the feasibility study in production and marketing. The destructive ... -
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 ... -
Plans and programmes of the SEAFDEC Leganes Station with emphasis on varied layouts and design of ponds
(South China Sea Fisheries Development and Coordinating Programme, 1977)As the importance of engineering to aquaculture becomes more apparent it is also realized that the physical properties of a pond have a strong influence on its productivity. This article reports the plans and programmes ... -
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" ... -
Effects of furanace on zoeae and mysis of Penaeus monodon.
(University of the Philippines at Los Baños, 1977)The toxicity of the chemotherapeutant Furanace on Z2 and M1 of the jumbo tiger prawn Penaeus monodon was assayed for a period of 24 hr. The LD50 for Z2 was 1.6 mg per liter; for ... -
Successful spawning of cultured Penaeus monodon Fabricius after eyestalk ablation
(Elsevier, 1977)Preliminary experiments resulted in successful spawning of captive stock of the prawn Penaeus monodon, or “sugpo”, to complete the life cycle and produce a viable F1 generation of larvae. Gonadal development was induced ...
