Assessment of some agarophytes from the coastal areas of Iloilo, Philippines. II. Seasonal variations in the agar quality of Gracilaria changii, Gracilaria manilaensis and Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1996)Three species of agarophytes (Gracilaria changii, G. manilaensis and Gracilariopsis bailinae) collected along the mud flats of Iloilo were investigated to determine the monthly variation in agar yield (%), gel strength (g ... -
Assessment of some agarophytes from the coastal areas of Iloilo, Philippines. I. Seasonal variations in the biomass of Gracilaria changii, Gracilaria manilaensis and Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1996)Monthly biomass (g dwt m-2) of Gracilaria changii, G. manilaensis and Gracilariopsis bailinae collected in four different coastal areas of Iloilo, Philippines showed significant differences. Gracilaria changii ... -
Growth, survival and feed conversion of juvenile shrimp (Penaeus monodon) fed a betaine/amino acid additive
(Society of Israeli Aquaculture and Marine Biotechnology, 1996)Diets low in animal but high in plant protein were enhanced with a chemoattractant FinnStim (FS), a betaine/amino additive. These were fed to juvenile shrimp, Penaeus monodon, in three tank experiments. All diets were ... -
Use of seaweed meals from Kappaphycus alvarezii and Gracilaria heteroclada as binders in diets for juvenile shrimp Penaeus monodon
(Elsevier, 1996)Two seaweed meals were tested as binders in shrimp diets. In the first study, Kappaphycus alvarezii or Gracilaria heteroclada in dry ground form were added to an isonitrogenous diet at 3, 5, 7 or 10%. The basal diet had ... -
Seasonal availability of calanoid copepods (genus Acartia) in eastern Thailand using a light trap, as food organisms for marine fish larval rearing
(Asian Fisheries Society, 1996)Zooplankton collected by the torch lighting method were investigated in a tropical coastal seawater pond in eastern Thailand. Copepods of the genus Acartia, such as A. sinjiensis, A. erythaea and A. pacifica, were predominant ... -
Valine requirement of postlarval tiger shrimp, Penaeus monodon Fabricius
(Wiley-Blackwell, 1996)The valine requirement of juvenile tiger shrimp, Penaeus monodon Fabricius, was determined. Shrimp postlarvae, PL20, with a mean weight of 14 mg, were randomly distributed in 36 oval 40-L capacity fibreglass tanks at 10 ... -
Methionine requirement of juvenile tiger shrimp Penaeus monodon Fabricius
(Elsevier, 1996)An 8-week feeding trial was conducted to determine the dietary requirement of postlarval Penaeus monodon for the sulfur-containing amino acid methionine. Shrimp postlarvae (mean weight 21 ± 0.3 mg) were reared in 40-1 ... -
Biomass and reproductive states of Gracilaria heteroclada Zhang et Xia collected from Jaro, central Philippines
(Walter de Gruyter, 1996)Biomass production and reproductive states were investigated to determine the abundance of Gracilaria heteroclada Zhang et Xia at Jaro, central Philippines from March 1990 to February 1991. Biomass of Gracilaria heteroclada ... -
Experiments on virulence dose and portals of entry for Aeromonas hydrophila in walking catfish
(American Fisheries Society, 1996)Aeromonas hydrophila, isolated from chevron snakehead Ophicephalus (=Channa) striatus affected with epizootic ulcerative syndrome (EUS), was injected intramuscularly into healthy walking catfish Clarias batrachus at varying ... -
Virulence and production of extracellular proteins (ECP) of Aeromonas hydrophila associated with the epizootic ulcerative syndrome (EUS) of freshwater fish
(University of the Philippines in the Visayas, 1996)Sixteen isolates of Aeromonas hydrophila isolated from normal, apparently normal and epizootic-ulcerative syndrome (EUS)-affected fish were screened for virulence and production of extracellular proteins (ECP). Results ... -
Economics of cultivating Kappaphycus alvarezii using the fixed-bottom line and hanging-long line methods in Panagatan Cays, Caluya, Antique, Philippines
(Springer Verlag, 1996)A socio-economic survey was conducted among the Kappaphycus alvarezii planters of Panagatan Cay, Caluya, Antique, Philippines to determine some social information, farming practices and cost and returns of farming the ... -
Economic analysis of prawn (Penaeus monodon) culture in the Philippines, II: Grow-out operations
(Asian Fisheries Society, 1996)The dramatic fall in prawn (Penaeus monodon) prices coupled with environmental concerns has resulted in a relative stagnation of prawn grow-out operations in the Philippines. Leaders of the Philippine aquaculture sector ... -
Bioactivity of stored luteinizing hormone-releasing analogue (LHRHa) in sea bass, Lates calcarifer Bloch
(Wiley-Blackwell, 1996)The spawning induction activity of dissolved and pelleted (D-Ala6, Pro9 N ethylamide) luteinizing hormone-releasing hormone analogue (LHRHa) stored for various periods was assessed in mature female ... -
Drug assimilation in the tissue of European sea bass (Dicentrarchus labrax) fry delivered orally through bioencapsulation
(Wiley-Blackwell, 1996)Assimilation levels of the antibacterials trimethoprim (TMP) and sulfamethoxazole (SMX) in sea bass (Dicentrarchus labrax) fry tissue administered orally were investigated. A 1:5 TMP and SMX combination incorporated in an ... -
Nursery rearing of the Asian sea bass, Lates calcarifer, fry in illuminated floating net cages with different feeding regimes and stocking densities
(Cambridge University Press, 1996)Successful rearing of hatchery-reared sea bass, Lates calcarifer, fry in illuminated floating cages was demonstrated in a 42-day experiment. Three feeding regimes, i.e. natural zooplankton (NZ) + minced fish flesh (MFF), ... -
Reproductive performance of four red tilapia strains in different seed production systems
(Society of Israeli Aquaculture and Marine Biotechnology, 1996)The reproductive efficiency of one Thai red tilapia strain (NIFI) and three genetically diverse Philippine red tilapia strains (BFS, FAC, and PF) were compared. Breeders from each strain were stocked separately in land-based ... -
The effect of background color and rotifer density on rotifer intake, growth and survival of the grouper (Epinephelus suillus) larvae
(Elsevier, 1996)Rotifer intake and early growth and survival of Epinephelus suillus larvae were determined in terms of rotifer visibility against the background color of rearing tanks and density. The larvae were stocked at 30 l−1 ... -
