Isolation and characterization of vitellin from the ovary of Penaeus monodon
(International Society of Invertebrate Reproduction and Development, 1990)
Female-specific protein (FSP, vitellogenin) in Penaeus monodon hemolymph and its related ovarian protein (vitellin, lipovitellin) were identified and characterized using electrophoretical and immunological procedures. The ...
Tissue distribution of mercury and selenium in minnows, Phoxinus phoxinus
(Springer Verlag, 1990)
The protective effect of selenium against mercury toxicity has been extensively demonstrated in a number of studies (Burke eta]. 1977; Kasuya 1976). Since mercury uptake is not always diminished by the presence of selenium ...
Organic pollution resulting from excess feed and metabolite build-up: Effect on Penaeus monodon postlarvae
(Elsevier, 1990)
Penaeus monodon postlarvae, PL, with mean weight and mean total length of 0.57 mg and 6.5 mm respectively, were stocked in aerated aquaria at 20 litre<sup>−1</sup> of seawater. They were fed minced shrimp meat at rates of ...
Interaction between test and reference populations when tilapia strains are compared by the “internal control” technique
(Elsevier, 1990)
Several strains of Oreochromis niloticus, O. mossambicus and their hybrids occur in the Philippines, and others are likely to be introduced or developed locally in the near future. Our objective was to study biological ...
Occurrence of luminous bacterial disease of Penaeus monodon larvae in the Philippines
(Elsevier, 1990)
Larval mortalities associated with luminescence have been observed in epizootic proportions in black tiger prawn (Penaeus monodon) hatcheries in Panay Island, Philippines. Luminescent vibrios, identified as Vibrio harveyi ...
Uptake and some physiological effects of mercury on water hyacinth, Eichhornia crassipes (Mart) Solms.
(SEAMEO, 1990)
The uptake and growth effects of mercury (Hg) on Eichhornia crassipes under field conditions and with lakewater as cultural medium were investigated. Absorption of the heavy metal increase with higher levels of Hg in the ...
Cryopreservation of the euryhaline rotifer Brachionus plicatilis embryos
(Elsevier, 1990)
A method for the separation and cryopreservation of Brachionus plicatilis embryos is described. Juveniles with uniform development were collected from a cultured stock by passing them through a series of nets. Collected ...
Vertical rope cultivation of Gracilaria (Rhodophyta) using vegetative fragments
(Walter de Gruyter, 1990)
Preliminary field culture of Gracilaria using vegetative fragments inserted between braids of ropes suspended vertically inside a floating cage was undertaken to assess the daily growth rate and monthly yield as influenced ...
The macronutrient composition of natural food organisms mass cultured as larval feed for fish and prawns
(Society of Israeli Aquaculture and Marine Biotechnology, 1990)
The macronutrient composition of natural food organisms that are mass cultured as feed for the larval stages of fish and prawns in the SEAFDEC Aquaculture Department was determined by chemical analysis. The food organisms ...
Spawning response latency and egg production capacity of LHRHa-injected mature female sea bass, Lates calcarifer Bloch
(Blackwell Publishing, 1990)
Mature female sea bass (Lates calcarifer Bloch) were injected once intramuscularly with 20 μg luteinizing hormone-releasing hormone analogue (D-Ala<sup>6</sup>, Pro<sup>9</sup>-LHRH-ethylamide) per kg body weight (BW) at ...
