Abstract

Cranoglanidid catfish are known to be typical of some fish fauna and well known for their delicious and nutritious meat. In Vietnam, they are found in the major river systems such as the Bang Giang river system (Bằng river and KyCung river), Thai Binh river system, Lo Gam river system, Chay river, Red river, Da river, Ma River, Ca River (Song Lam). Diversity of cranoglanidid catfish remains unclear and their identification by morphology has given different views. Cranoglanidid use of morphological identification and molecular identification has recently been a new approach. Our present study using both these methods of identification is to elucidate the identity of Cranoglanidid catfish species living in Lam river system based on specimens collected in Tuong Duong, Con Cuong, Thanh Chuong and Nam Dan (Lam river system, Nghe An, Vietnam).

Keywords

Cranoglanidid catfish, identification, morphology, molecular identification.

Conclusion

Conclusion: Cranoglanidid catfish living in Lam river are Cranoglanis bouderius (Richardson, 1846) Recommendation: it is necessary to collect more Cranoglanidid catfish specimens from various geographical areas for morphological and molecular identification in order to obtain the better understanding of the diversity of the genus Cranoglanis.

Cranoglanidid catfish are known to be typical of the South China and Northern Vietnam fish fauna. They live at bottom and near bottom, preferring moderately and slowly running waters with much sandy and muddy bottom. They usually live in colonies and are found mainly in the downstream of rivers in Northern provinces. Cranoglanidid catfish are famous for their tasty and nutritious meat. Their local names are Ngạnh fish (large fish), hau fish (small fish), haumùn fish, hautrunghoa fish (Vietnamese name), Papé (Thai name). Cranoglanis catfish are categorized as VU in the IUCN Red List. In the world, the catfish Cranoglanis henrici is distributed in Thailand, Philippines, Indonesia, China (Hainan island, Guangdong, Guangxi, Yunnan) and Vietnam (Pravdin, 1963, Red Book of Vietnam). In Vietnam, Cranoglanidid catfish are found in all river systems from the North to the South of central Vietnam, but not found in the South. In the North, catfish can be found in major river systems such as
