Early larval development of the seabass Lates calcarifer with emphasis on the transition of energy sources
(Japanese Society of Fisheries Science, 1986)The early growth, yolk and oil globule resorption, early morphological and behavioral de-velopment, and initial feeding of hatchery-raised Lates calcarifer were studied. Based on the developmental events and the energy the ... -
The response of Penaeus monodon juveniles to varying protein/energy ratios in test diets
(Elsevier, 1986)Two sets of factorial experiments were conducted for 8 weeks to determine the response of Penaeus monodon juveniles (average weights = 0.60 ± 0.16 g and 0.80 ± 0.05 g) to diets containing various protein/energy ratios. The ... -
Spontaneous maturation and spawning of milkfish in floating net cages
(Elsevier, 1986)Milkfish (Chanos chanos Forsskal) reared from wild-caught fry and from hatchery-bred fry matured at 3.5-5.5 years (2.3-4.9 kg). Maturation and spawning of the hatcherybred fish marks the first time the milkfish life-cycle ... -
The milkfish seed resources survey in Sri Lanka: Status, problems and recommendations
(Ministry of Fisheries and Aquatic Resources, Sri Lanka, 1986)A summary is provided of information concerning the milkfish (Chanos chanos) seed resources of Sri Lanka, highlighting problems related to seed collection. Various recommendations are made to overcome these problems and ... -
Studies on the chronic soft-shell syndrome in the tiger prawn, Penaeus monodon Fabricius, from brackishwater ponds
(Elsevier, 1986)Prawn culture is becoming more widespread in the Philippines. In recent years, prawn production in brackishwater ponds has been adversely affected by a chronic soft-shell syndrome. A field survey of prawn ponds in the ... -
The length-weight relationship, food habits and condition factor of wild juvenile milkfish in Sri Lanka
(Elsevier, 1986)Wild juvenile milkfish (Chanos chanos) were obtained from Negombo lagoon in September 1984. Thirty-one specimens (92–186 mm FL) had a fork length-body weight relationship of log W = −5.6083 + 3.2598 log L. These fish were ... -
Growth, survival and macronutrient composition of Penaeus monodon Fabricius larvae fed with Chaetoceros calcitrans and Tetraselmis chuii
(Elsevier, 1982)Penaeus monodon larvae were reared from zoea1 (Z1) to mysis3 (M3) using two different algal feeds, Chaetocero calcitrans and Tetraselmis chuii. Artemia nauplii were added to both ... -
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 ... -
