Juvenile African catfish were fed diets contaminated with aflatoxin B1 and fumonisin B1, with or without lanthanum chloride at 200 or 400 mg/kg, for 56 days. Fish given lanthanum chloride grew better and had better blood and serum enzyme profiles than fish fed the contaminated diet alone. Lanthanum residues in fish tissue were not measured.
Key numbers
- Lanthanum chloride inclusion: 200 mg/kg (diet C) and 400 mg/kg (diet D) of feed, with 19.7 µg/kg aflatoxin B1 and 28.5 mg/kg fumonisin B1 (Table 1, abstract).
- Feeding period 56 days; sampling on days 7, 28 and 56 (abstract).
Methods (brief)
Fish were assigned to control, mycotoxin-contaminated, and two lanthanum-chloride-amended contaminated diets; growth, hematology and serum biochemistry were compared by analysis of variance.
Evidence fitness
Supports the statement that lanthanum chloride is studied as a feed additive in fish farming. It does not provide lanthanum levels in fish flesh or any human exposure estimate.
Limitations
No tissue lanthanum analysis; single species and short trial; the abstract mentions five groups while four diets are described.
