Accumulation and excretion of metal granules in the prawn, Penaeus monodon, exposed to water-borne copper, lead, iron and calcium
(Elsevier, 1994)
Juveniles of the giant tiger prawn, Penaeus monodon, were exposed for 10 days to 1 mg/l copper, lead, iron or calcium in order to investigate the formation and accumulation of metal granules in major soft tissues as well ...
Vaccination of European sea bass fry through bioencapsulation of Artemia nauplii
(European Aquaculture Society, 1994)
European sea bass (Dicentrarchus labrax) fry vaccinated orally via bioencapsulation in Artemia nauplii or by bath method exhibited better performance than control fish in terms of growth, food conversion and resistance to ...
Ammonia excretion in Penaeus monodon postlarvae during handling and transfer
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)
The ammonia excretion rate was used as an index of the physiological state of Penaeus monodon poltlarvae (PL) by monitoring excretion rates after handling and transfer to physiologically different media. The ammonia excretion ...
Effect of delayed feeding of Artemia salina and partial replacement by Moina macrocopa on growth and survival of sea bass, Lates calcarifer (Bloch), larvae.
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)
One-day old sea bass larvae (0.93-2.03 mm total length, 0.94-1.00 mg wet body weight) were stocked at a density of 30 larvae per liter in nine 250 l capacity fiberglass tanks. Fish were reared for 26 days on three different ...

(International Society of Invertebrate Reproduction and Development, 1994)
The comparative morphology of the foregut during development from embryonic larva to adult in Cherux quadricarinatus was examined by light and scanning electron microscopy. Major ontogenetic changes occurred in the gastric ...
Thyroid hormone surges during milkfish metamorphosis
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)
Both thyroxine (T<sub>4</sub>) and triiodothyronine (T<sub>3</sub>) were detected in fertilized eggs and larvae of milkfish. The concentration of T<sub>4</sub> was lower than that of T<sub>3</sub> only in fertilized eggs ...
Agar production from Gracilariopsis heteroclada (Gracilariales, Rhodophyta) grown at different salinity levels
(Walter de Gruyter, 1994)
Gracilariopsis heteroclada grown in fiber glass tanks at four salinity levels was treated with three different concentrations of aqueous NaOH. Yield, gel strength, gelling and melting temperatures of the extracted agar ...
Aflatoxin B1 contamination of shrimp feeds and its effect on growth and hepatopancreas of pre-adult Penaeus monodon
(Society of Chemical Industry, 1994)
A survey of aflatoxin B<sub>1</sub> (AFLB<sub>1</sub>) levels in commonly used commercial shrimp finisher feeds in the Philippines showed a various range of values from not detected to 120 μg kg<sup>−1</sup> using ...
Growth and food consumption of milkfish (Chanos chanos) during dry and wet seasons
(Serials Publications, 1994)
This study was conducted to evaluate the quality of the food consumed by the fish, to estimate the food consumption of the fish in the natural environment during the wet and dry seasons, and to determine the relationship ...
