Molluscicidal activity of tobacco dust against brackishwater pond snails (Cerithidea cingulata Gmelin)
(Elsevier, 1998)
Toxicity tests on the effect of tobacco dust against brackishwater pond snails (Cerithidea cingulata Gmelin) of various stages or size ranges were conducted under controlled laboratory conditions. The 72-h LC<sub>50</sub> ...
Sulfide as an environmental factor and toxicant: Tolerance and adaptations in aquatic organisms
(Elsevier, 1992)
This review brings together a large number of independent and seemingly unrelated studies in various disciplines under four major topics: (1) sulfide as an environmental factor in aquatic habitats; (2) sulfide as a toxicant; ...
Acute nitrite toxicity and methemoglobinemia in juvenile milkfish (Chanos chanos Forsskal)
(Elsevier, 1987)
Nitrite was about 55 times more toxic to milkfish juveniles in fresh water than in 16% brackish water: the 48-h median lethal concentrations were 12 mg NO<sub>2-</sub>N/l (95% confidence limit=7.4–19.6) and 675 mg ...
Gill lesions associated with acute exposure to ammonia.
(University of the Philippines, 1982)
The histopathological effects of the 96 hr LC<sub>50</sub> at 20.65 ppm NH<sub>3</sub>-N on the gills of milkfish fingerlings were examined qualitatively. Lesions observed were hypertrophy, hyperplasia, fusion of the ...
Toxicity of malachite green to the larvae of Penaeus monodon
(University of the Philippines at Los Baños, 1978)
The toxicity of malachite green to the larvae of the jumbo tiger prawn Penaeus monodon was determined in a static bioassay. Daily larval death was directly proportional to the chemical concentration of and exposure time ...
Uptake and depuration of mercury in the green mussel, Perna viridis Linnaeus (Bivalvia: Mytilidae)
(Science and Technology Information Institute, 1985)
P. viridis were exposed to 3.6 ppb, and 100 ppb mercury. The mussels were also fed with algae that had been precontaminated with mercuric acetate to give a final mercury concentration of 10 ppb. Mercury bioaccumulation ...
Acute toxicity of nitrite to mud crab Scylla serrata (Forsskål) larvae
(Blackwell Publishing, 2007)
Early larval stages of mud crab Scylla serrata were exposed to different concentrations of nitrite (40, 80 and 160 mg L<sup>−1</sup> and a control, without added nitrite) and three salinity levels (25, 30 and 35 g ...
Histopathological response of milkfish Chanos chanos Forsskal fingerlings to potassium permanganate
(Japanese Society of Fish Pathology, 1986)
Static 96 h bioassays were conducted on milkfish fingerlings at concentrations ranging from 1.00 to 1.80 mg/l KMnO<sub>4</sub>. Histopathological analyses of gills, liver, and kidney tissues revealed significant changes ...
Use of metaldehyde as a molluscicide in semi-commercial and commercial milkfish ponds
(Elsevier, 1998)
The effect of metaldehyde on brackish water pond snails, Cerithidea cingulata, was tested in 250 m2 ponds, and in semi-commercial and commercial milkfish ponds. The field trials were conducted at three locations, namely ...
Acute toxicity of potassium permanganate to milkfish fingerlings, Chanos chanos
(Springer Verlag, 1989)
Potassium permanganate (KMnO<sub>4</sub>) is a strong oxidizing agent and is commonly used in aquatic systems to improve available oxygen, treat infectious diseases and parasites, detoxify fish poisons, and control algae. ...
