Changes in the steroid hormone and vitellogenin levels during the gametogenic cycle of the giant tiger shrimp, Penaeus monodon
(Elsevier, 1994)
The levels of estradiol-17β, and progesterone in the hemolymph, ovaries and hepatopancreas, in relation to the vitellogenin levels of captive female Penaeus monodon, were determined during the gametogenic cycle. Estradiol ...
Effect of pH and ammonia on survival and growth of the early larval stages of Penaeus monodon Fabricius
(Elsevier, 1994)
Lethal toxicity tests of ammonia at different pH levels (7, 7.5, 8, and 8.5) and its effect on survival and growth of the early larval stages of Penaeus monodon were determined. An increase in ammonia toxicity when the ...
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 ...
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 ...
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 ...
L-ascorbyl-2-phosphate Mg as source of vitamin C for juvenile Penaeus monodon
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)
Phosphated ascorbic acid (MAP), a stable vitamin C derivative, was used in practical diets for Penaeus monodon (wet weight, 126-254 mg) as a source of vitamin C. In Experiment I, the levels were from 0 to 1,500 ppm MAP. ...
