The effects of artificial diets on fry production and growth of Oreochromis niloticus breeders
(Elsevier, 1985)Tilapia breeders were fed with pelleted supplemental diets containing 20 or 40% crude protein at a daily feeding rate of 1% of fish biomass for 24 weeks in cages and tanks. Breeders were weighed and fry were collected at ... -
Weaning of hatchery-bred milkfish larvae from live food to artificial diets
(Elsevier, 1984)Two-week old milkfish (Chanos chanos ) larvae (7.5 mm standard length, 2.3 mg wet body weight) previously fed only rotifers were weaned abruptly to six artificial diets (commercial feed TP, artificial plankton AS and BP, ... -
Small scale tilapia cage technology adopted in fishing villages in Laguna Lake, Philippines
(Elsevier, 1984)A small-scale tilapia cage project was tested in two fishing villages in the Philippines. The results showed that household incomes of participating families increased from P6183 to P41 768 per year, and household savings ... -
Effect of varying dietary crude protein levels on spawning frequency and growth of Sarotherodon niloticus breeders
(Fisheries Research Society of the Philippines, 1983)Four-month-old S. niloticus breeders were fed with dry pellets containing 20 to 50% crude protein in two separate experiments. Their frequency of spawning and their growth in length and weight were determined over a 16-week ... -
Some histological observations on the opaque eyes of milkfish Chanos chanos Forskal
(Fisheries Research Society of the Philippines, 1983)In a study on energy-protein requirements of milkfish fingerlings using semi-purified diets, several gross observations were made on individual milk-fish such as fin and tail rot, yellowish coloration of the abdomen, opacity ... -
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 ... -
