A comparative study of various extenders for milkfish, Chanos chanos (Forsskal), sperm preservation
(Elsevier, 1982)Various extenders, containing potassium chloride, sodium chloride, glucose, sodium citrate, Ringer's solution, cow serum and milkfish serum were used to preserve milkfish (Chanos chanos) sperm at near-zero temperatures ... -
Effects of food ration on growth, condition factor, food conversion efficiency, and net yield of estuary grouper, Epinephelus salmoides Maxwell, cultured in floating net-cages
(Elsevier, 1982)The effects of food ration on the growth and yield of the estuary grouper raised in floating net-cages were investigated. The optimum ration given on alternate days was 5% body weight (wet) which gave the best mean fish ... -
Studies on the carbohydrates in the digestive tract of the milkfish Chanos chanos
(Springer Verlag, 1981)Crude extracts from various regions of the digestive tract of pond grown milkfish were tested forttheir ability to catalyze the hydrolysis of various carbohydrates. The most active carbohydrases were those involved in the ... -
Acclimation of Penaeus monodon postlarvae to fresh water
(Fisheries Research Society of the Philippines, 1980)Gradual acclimation of Penaeus monodon Fabricius to fresh water was conducted in glass aquaria and marine plywood tanks over a one-day, two-day, and three-day acclimation periods. Different stages of postlarvae were ... -
Changes in the length and weight of milkfish, Chanos chanos, larvae preserved in formalin
(Fisheries Research Society of the Philippines, 1980)Shore-caught milkfish fry (late postlarvae) and artificially-bred, laboratory-reared larvae (0-to 20-day old) were preserved in 5% and 10% freshwater-and/or seawater-formalin solutions after measuring their initial weights ... -
Ipil-ipil leaf meal as supplemental feed for T. nilotica in cages
(Fisheries Research Society of the Philippines, 1980)Tilapia nolotica fingerlings were grown to marketable size in cages in Laguna Lake at a stocking density of 150/m super(2). Those given supplemental feed of ipil-ipil leaf meal at varying levels showed faster growth compared ... -
Development of the external genitalia of the giant prawn, Penaeus monodon
(The Japanese Society of Scientific Fisheries, 1980)The present paper deals with the morphological development of the external genitalia of Penaeus monodon which will serve as a basis for future researches on the reproductive biology of this species. The petasma length is ... -
The food and feeding habit of Penaeus monodon Fabricius collected from Makato River, Aklan, Philippines (Decapoda: Natantia)
(E.J. Brill, 1980)The food of Penaeus monodon Fabricius collected from Makato River, Aklan, consisted mainly of Crustacea (small crabs and shrimps) and molluscs, making up 85% of ingested food. The remaining 15% consisted of fish, polychaetes, ... -
The optomotor reaction of milkfish larvae and juveniles
(Japanese Society of Fisheries Science, 1980)The development of the optomotor reaction (OMR) in milkfish (Chanos chanos), from the larval, through the metamorphic, to the juvenile stage was observed. The period from the appearance of the pelvic fins until the complete ... -
Larval and postlarval development of the window pane shell, Placuna placenta Linnaeus, (Bivalvia: Placunidae) with a discussion on its natural settlement.
(California Malacozoological Society, Inc., 1980)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 ... -
On the visual feeding of milkfish larvae and juveniles in captivity
(The Japanese Society of Scientific Fisheries, 1980)Feeding of milkfish (Chanos chanos) larvae and juveniles on Artemia nauplii in captivity was observed. The retinae of the larvae were observed histologically. Milkfish larvae could not take food in the dark. The juveniles ... -
A comparison of macronutrient levels in green mussel (Perna viridis) and brown mussel (Modiolus metcalfei Hanley)
(The Science Society of Thailand, 1980)Two species of mussel from Panay Island, Philippines, have been analyzed for moisture, crude protein, crude fat, ash, carbohydrated, crude fibre and minerals (calcium and phosphrus). Results showed that the brown mussel ... -
Effects of exogenous hormone injections on milt consistency in newly caught, wild milkfish
(University of the Philippines at Los Baños, 1980)The study was conducted to study the effects of single injections of Human Chorionic Gonadotropin (HCG) (Ayerst Laboratories, Inc) and Durandron Forte 250, a long-acting androgen preparation (N.V. Organon Oss, Holland), ... -
Studies on the egg quality of Penaeus monodon Fabricius, based on morphology and hatching rates
(Elsevier, 1981)Eggs of Penaeus monodon are classified into five different types on the basis of morphological criteria and hatching rates — A1 eggs undergo normal development with 58% hatching rate; A2 eggs show delayed and/or abnormal ... -
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 ... -
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 ... -
