Transition from endogenous to exogenous nutrition sources in larval rabbitfish Siganus guttatus
(Japanese Society of Fisheries Science, 1988)The early larval development of Siganus guttatus was studied with emphasis on the transition from endogenous to exogenous feeding. Three rearing trials were conducted as follows: 1) rearing in a 5 ton concrete tank at ... -
Aeromonas hydrophila associated with ulcerative disease epizootic in Laguna de Bay, Philippines
(Elsevier, 1987)Aeromonas hydrophila was consistently associated with necrotic ulcers and lesions in mudfish/snakehead (Ophiocephalus striatus), Thai catfish (Clarias batrachus), crucian carp (Carassius carassius) and goby (Glossogobius ... -
Morphological aspects of the development of swimming and feeding functions in the milkfish Chanos chanos
(The Ichthyological Society of Japan, 1987)Development of swimming and feeding abilities based on morphological development of larval and early juvenileChanos chanos was investigated. In larvae smaller than about 6.5 mm SL, mechanical supports of fins and branchial ... -
Effects of Chlorella-feeding on larval milkfish, Chanos chanos, as evidenced by histological monitoring
(Elsevier, 1987)Milkfish, Chanos chanos, larvae were found to suffer 100% mortality within 6 days of feeding when reared on Chlorella sp. According to the liver ultrastructure, Chlorella-fed fish underwent starvation. Likewise, no signs ... -
Nutrition-related histopathology of the intestine of milkfish Chanos chanos fry
(Inter Research, 1987)A histopathological study was conducted on the intestine of milkfish larvae Chanos chanos, subjected to different nutritional conditions. Newly caught milkfish fry, ca 20 d old, were starved for 7 d and and then fed with ... -
Influence of feeding rate and diet form on growth and survival of Nile tilapia (Oreochromis niloticus) fry
(Elsevier, 1987)Young Nile tilapia (12 mg mean body weight and 11 mm total length) were stocked at a density of 5 fish/l in twelve 50-l aquaria filled with 30 l of tap water. They were fed pellet crumbles containing 35% crude protein at ... -
Evaluation of the high rate algae pond system for softdrink waste treatment and for fish culture.
(Asean Journals Ltd., 1987)The High Rate Algae Pond System (HRAP) as secondary treatment for Cola effluents showed potential for reducing both COD load (about 88%) and high pH level (down to pH 7.0 -8.0). The effluent quality improved and can be ... -
Responses of intermolt Penaeus indicus to large fluctuations in environmental salinity
(Elsevier, 1987)The osmotic and chloride regulation by 5- to 10-g intermolt Penaeus indicus was investigated by abruptly changing medium salinity from seawater (32 ppt) to test salinities of 8, 20, 32 (control) or 40 ppt. Hemolymph samples ... -
Algal production in wastewater: Progress and problems.
(E. Schweizerbartsche Verlagsbuchhandlung, 1987)Algal production in wastewater is reviewed in two major areas: (1) production of single-cell proteins, and (2) its integration with aquaculture for the production of natural feeds. Progress achieved so far in the various ... -
Observation on the host-parasite relationship of Epipenaeon ingens Nobili (Epicaridea: Bopyridae) and Penaeus semisulcatus De Haan.
(Science and Technology Information Institute, 1987)Sample of Penaus semisulcatus or Tiger Shrimp ("hipong bulik") from Manila Bay and Tayabas bay, and from waters off Palawan, Cebu, Samar and Capiz were obtained from Navotas Fishery Port during the period from March, 1978 ... -
The effects of iron compounds on the virulence of Vibrio anguillarum in Japanese eels and ayu
(Japanese Society of Fish Pathology, 1987)When Japanese eels (Anguilla japonica) were injected intramuscularly (IM) with ferric ammonium citrate (FAC) at a sublethal dose of 10 µg/g and followed by IM-injection with various doses of Vibrio anguillarum, FAC injection ... -
Fate and location of Vibrio anguillarum in tissues of artificially infected ayu (Plecoglossus altivelis)
(Japanese Society of Fish Pathology, 1987)Ayu (Plecoglossus altivelis) were infected with Vibrio anguillarum by a water-born method. At 6, 12, 18, 36, 38-45 (moribund stage) and 48 h (dead) after infection, fish were sampled to determine the fate and location of ... -
Induced spawning of maturing milkfish (Chanos chanos Forsskal) with gonadotropin-releasing hormone (GnRH) analogues administered in various ways
(Elsevier, 1987)The response of mature female captive milkfish to mammalian and salmon gonadotropin-releasing hormone analogues (mGnRH-A and sGnRH-A) was investigated. Prior to spawning, six groups of three females received (1) 10–16 μg ... -
Maturation and spawning of Penaeus indicus using different ablation methods
(Elsevier, 1987)Wild immature Penaeus indicus females (11.5 ± 3.1 g body weight) were ablated by pinching, cautery or tying of one eyestalk, and stocked with control (unablated) females and males (9.2 ± 1.5 g) in a 12-m3 ... -
Studies on the causative organism of Oreochromis niloticus (Linnaeus) fry mortalities I. Primary isolation and pathogenicity experiments.
(Taylor & Francis, 1987)Oreochromis niloticus fry reared in 50 L aquaria at a density of 1,000 fry manifested mortalities of 15% daily. Afflicted two-week old fry exhibited darker pigmentation, emaciation lesions, and surface swimming. Parasites ... -
The effects of water hardness on the hatching and viability of silver carp (Hypophthalmichthys molitrix) eggs
(Elsevier, 1987)An investigation was conducted to establish water hardness concentration for optimum hatching of silver carp (Hypophthalmichthys molitrix) eggs. Eggs were incubated for 19 h at 26.5°C at six levels of water hardness: 100, ... -
Development of the digestive tract of milkfish, Chanos chanos (Forsskal): Histology and histochemistry
(Elsevier, 1987)The digestive tract of the newly hatched milkfish larva is a simple undifferentiated tube. Three days after hatching, differentiation of the esophagus begins with development of mucous-secreting cells. At this time, the ... -
Osmotic and chloride regulation in the hemolymph of the tiger prawn Penaeus monodon during molting in various salinities
(Springer Verlag, 1987)The effect of molting on osmotic and chloride concentrations in the blood of the prawn Penaeus monodon Fabricius (20±3 g) at various salinities was investigated. Prawns were obtained from ponds in Iloilo, Philippines, in ... -
Histopathology of the chronic soft-shell syndrome in the tiger prawn Penaeus monodon
(Inter Research, 1987)One of the disease problems that affect the production of tiger prawn Penaeus monodon Fabricius in brackish-water ponds is the chronic soft-shell syndrome, a condition in which the prawn shell is persistently soft for ... -
The economics of retarding milkfish growth for fingerling production in brackishwater ponds
(Elsevier, 1987)Two experiments were conducted to measure the economic viability of retarding milkfish growth (stunting) in brackishwater ponds. In the first experiment, 2-month-old fish were reared for 6 months in ponds with initial ...
