The economics of the milkfish fry and fingerling industry of the Philippines
(International Center for Living Aquatic Resources Management; Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)The fry and fingerling industry of the milkfish (Chanos chanos Forskal) in the Philippines is alleged to suffer from certain imperfections. Primary among these are an annual shortage of catch necessary to meet the stocking ... -
Edible crustaceans in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978-12)Cursory information on the biology and economic value of sugpo (Penaeus monodon ) relevant to aquaculturists is presented. -
Effect of a diet lacking in vitamin and mineral supplements on the growth and survival of Penaeus monodon juveniles in a modified extensive culture system
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)Penaeus monodon juveniles (mean weight, 0.006 g) were reared in 330 m earthen ponds for 120 days at a stocking density of 7.5/m2 under conditions of the modified extensive system of culturing shrimps. The shrimps were fed ... -
Effect of carrageenan micro-binded diet on the larval stages of Penaeus indicus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)At present, most hatcheries depend on live food like diatoms, Chlorella, rotifer and brine shrimp to rear the larval stages of various penaeid species. Mass production of live feed requires much space (tanks) and labor, ... -
Effect of cholesterol in artificial diets for Mediterranean prawns
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Mediterranean prawn (Penaeus kerathurus Forsskal) postlarvae (2 months old) were fed ad libitum with previously tested artificial diet (41% D.W., mainly of vegetal origin) supplemented with different percentages of cholesterol ... -
Effect of dietary astaxanthin and vitamin A on the reproductive performance of Penaeus monodon broodstock
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)Reproductive performance of pond-reared tiger shrimp given astaxanthin (100 mg/kg diet) and Vitamin A (20,000 IU) for 61 days was assessed in a 2x2 factorial experiment in a completely randomized design. Mean gonad index ... -
Effect of dietary fatty acids on the fatty acid composition of Penaeus monodon juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Six purified diets containing either pollack liver oil or a combination of dietary fatty acids (18:1ω9, 18:3ω3, 20:5ω3) at 5% level and a control (no lipid) were assessed for their influence on the fatty acid composition ... -
The effect of different binders on the water stability of feeds for prawn
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)Corn starch, gelatin, sago palm starch, agar, and bread flour were tested for their binding capacity in pelleted diets for Penaeus monodon . Agar was found to be good binder, but it costs too much, while bread flour was ... -
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. -
The effect of different levels of vitamins premix in the diet of African catfish (Clarias gariepinus) fingerlings
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)The present study was conducted to determine the growth and survival of African catfish (Clarias gariepinus) fingerlings fed diets with various levels of vitamin premix. The fingerlings (mean weight, 1.55 to 2.12 g) were ... -
Effect of different light intensities on the growth of the diatom Chaetoceros calcitrans
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)Batch cultures of C. calcitrans were maintained indoors at a temperature range of 21 to 25 C and continuously illuminated by 40-watt daylight fluorescent lights. Cultures were exposed to 5 different intensities from 200 ... -
Effect of different sex ratios of ablated wild-stock Penaeus monodon Fabricius on maturation, fecundity and hatching rates
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979) -
Effect of feed binder on water stability and digestibility of formulated feed for the mud crab Scylla serrata
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)The binding capacity of six natural and eight synthetic feed binders were tested in a basal diet formulated for the mud crab. Incorporation levels of natural binders ranged from 1 to 25% while those of synthetic binders ... -
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 ... -
Effect of furanace on the development of larval stages of Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)Zoea 2 (Z2), Mysis 1 (M1) and Postlarva 1 (P1) of P. monodon artificially spawned in closed-system concrete hatchery tanks were bioassayed for their tolerance to the antibiotic furanace. ... -
Effect of nitrite, ammonia, and temperature on P. monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)P. monodon larvae were studied for the effects of temperature, ammonia, and nitrite on survival. Toxicity levels of nitrite were found to vary with larval stage. Larvae could tolerate ammonia up to about 10 ppm, with the ... -
Effect of some physico-chemical factors on the survival and growth of Penaeus monodon postlarvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)Growth and survival rates of P. monodon postlarvae were examined at different temperatures, salinities, and nitrite and ammonia concentrations, using one feed level. Condition of postlarvae greatly affected the experimental ... -
