Larval and postlarval development of the window-pane shell, Placuna placenta L. (Bivalvia: Placunidae)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)Stages of development of P. placenta from the straight-hinge veliger to the adult are described. Mature larvae metamorphose at lengths from 220-230 m. Larvae probably attach byssally to the water surface at metamorphosis ... -
Experiments on the induced spawning and larval rearing of the milkfish, Chanos chanos (Forsskal) in 1979
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)This paper summarizes the results of the experiments on the induced breeding and larval rearing of milkfish during the 1979 season. -
Preliminary trials in Artemia rearing and salt production in earthen salt ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)The authors report on the production of Artemia obtained on a 0.5 ha pilot project with combined trials in Artemia rearing with solar salt production during the dry seasons and with production of milkfish (Chanos chanos) ... -
Successful inoculation of Artemia and production of cysts in man-made salterns in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)The authors report on inoculation experiments of Artemia nauplii and young adults of the San Francisco Bay strains in earthen fish ponds. The test inoculated proved successful where water salinity ranges from 20 to 32 ... -
Preliminary study on the internal genital organ of the giant tiger prawn, Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)This report gives information on the anatomy of the internal genital organs of male and female Penaeus monodon. -
Effect of different feeding regimes on reproduction and survival of ablated Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)Results of experiments conducted on ablated Penaeus monodon, fed with 4 different feeds (pellet-pellet, mussel-mussel, mussel-pellet and squid-pellet), on survival, spawning, fecundity and hatching rate are given and discussed. -
Mass production of Penaeus monodon Fabricius juveniles in earthen nursery ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)Different culture techniques were tried for rearing larvae of Penaeus monodon , in order to obtain preliminary data on stocking density, water management, fertilization versus feeding and effect of different types of ... -
Fishwater and agar as binders in a prawn diet
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)The objectives of the study were to find out the proportion of water to fish fins, skin and bones that would give a good gel and to determine the effect of a combination of fish water and commercial crude agar on the water ... -
Selection and application of a suitable sampling method for quantitative and qualitative evaluation of lab-lab
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)Milkfish and prawn pond operation in the Philippines is often associated with lab-lab culture. Lab-lab is a biological complex of blue-green algae, diatoms, bacteria and various animals which form a mat at the bottom of ... -
Effect of feeding rate on the survival and growth of milkfish (Chanos chanos) fry in a controlled environment
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)The optimum daily feed allowance varies with species, age, size, frequency of feeding, culture procedures, quality of feed and water quality. This experiment indicated that with a diet containing 40% protein and 3,450 kcal ... -
Preserved algae as food for Penaeus monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)Uni-algal cultures of C. calcitrans, S. costatum, T. chui and Isochrysis sp. obtained from the laboratory were harvested. The harvest, preserved by either freezing or sun-drying, was fed to the larvae of P. monodon . Among ... -
The use of decapsulated brine shrimp eggs as food for shrimp larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)Decapsulated cysts of Artemia salina were experimentally fed to the larvae of Penaeus monodon, Metapenaeus ensis, M. endeavouri and Macrobrachium rosenbergii and were found to be comparable to freshly hatched brine shrimp nauplii. -
Minimum dissolved oxygen tolerance of four different sizes of milkfish
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)Four size groups of milkfish were tested, 4-18 g, 20-34 g, 35-95 g and 200-300 g. A number of fish from each group were placed separately in identical 1.2 m2 wooden tanks containing seawater filled up to 30 cm ... -
Preliminary histological study of the ovarian development of the giant tiger prawn, Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)This study was undertaken to determine structural characteristics within the gonads which might serve as an index to age and longevity and furnish information on the frequency of spawning of an individual. -
