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. -
Experiments on the induced breeding of milkfish, Chanos chanos (Forsskal) in 1978
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)Results indicated that a female having eggs with an average diameter of < 0.7 mm did not respond well to the hormone injections. -
A preliminary study on the growth and survival of stunted and non-stunted milkfish fingerlings
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)A study was conducted comparing the growth of stunted and non-stunted milkfish. -

(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)A brief account is given of experiments undertaken rearing Penaeus monodon larvae fed on diatom (Chaetoceros calcitran) and fermented vegetable trash, which included fruits and their peels, vegetables and rice. The possible ... -
Notes on the pigmentation pattern in the larval developmental stages of laboratory-reared milkfish
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)Milkfish fry were artificially bred and reared in the laboratory and the pigmentation pattern of the different developmental stages of the larvae are described in detail, with illustrations. -
Ferrocement buoys for mussel culture
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)A method is described for culturing mussels (Mytilus smaragdinus) using ferro-cement buoys, which may be used in the construction of a raft house or a flotation system for nets and cages. -
Preliminary report on the first production of the crab stages of alimasag, Portunus pelagicus (Linnaeus)
