Larval and early juvenile fishes associated with milkfish fry at Malandog, Hamtik, Antique
(Fisheries Research Society of the Philippines, 1983)From 5 May 1981 to 7 November 1981 a total of 122,841 specimens of milkfish fry and early juvenile fishes was collected with the use of a milkfish fry sweeper. Of these, 66,361 or 54.02% consisted of early juvenile stages ... -
Dietary crude protein requirement of Tilapia nilotica fry
(University of the Philippines at Los Baños, 1982)Tilapia fry were stocked at three per liter in wooden tank compartments or glass aquaria filled with 50 or 35 l of fresh water in three separate feeding trials. The fry were fed isocaloric practical diets containing 20, ... -
Fry-to-fingerling production of Tilapia nilotica in aquaria using phytoplankton as natural feed
(University of the Philippines at Los Baños, 1982)Two experiments were conducted to demonstrate the efficiency of phytoplankton as natural feed in fry-to-fingerling production of Tilapia nilotica . In the first experiment, growth and survival rates of fry given a sustained ... -
Management of brackishwater pond for milkfish fingerling production in Sri Lanka
(Ministry of Fisheries and Aquatic Resources, 1982)The author reviews the present methods of milkfish (Chanos chanos) fry collection and presents his observations and recommendations of improvement. -
Milkfish fry and fingerling resources of Sri Lanka
(Ministry of Fisheries and Aquatic Resources, 1982)Sri Lanka has the milkfish (Chanos chanos) seed and water resources for the development of milkfish aquaculture as a new industry. Milkfish fry and fingerlings are present in all surveyed coastal wet lands, but are abundant ... -
Gum arabic, carrageenan of various types and sago palm starch as binders in prawn diets
(Fisheries Research Society of the Philippines, 1982)Sago palm starch, gum arabic and three types of carrageenan (EPT-2, St-0008-29 & St-008-30A) were tried as binders in a practical diet. EPT-2 carrageenan gave consistently better water stability than the other binders in ... -
Evaluation of milkfish (Chanos chanos Forskal) and prawn (Penaeus monodon Fabricus) in polyculture system
(Fisheries Research Society of the Philippines, 1982)The growth, survival and profitability of milkfish (C. chanos ) and prawn (Penaeus monodon ) (averaging 3.1 g and 0.3 g, respectively) grown in five different combinations for 100 days in 500-m super(2) brackishwater ponds ... -
Effects of increased stocking density and supplemental feeding on the production of milkfish fingerlings
(Fisheries Research Society of the Philippines, 1982)Experiments were conducted in twelve 144 sq. m. brackishwater ponds at Leganes Research Station, SEAFDEC, to determine the effect of increased stocking density and supplemental feeding on milkfish fingerling production. ... -
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 ... -
