“…Clarias dayi is a very rare species being known only by a single specimen collected by Dr. Francis Day in 1877. Clarias dussumieri is listed as a threatened fish (Padmakumar et al, 2010). Clarias magur is a commercially cultivated species found all over India.…”

Mitochondrial cytochrome C Oxidase I (COI) sequence variation among the clariid fishes of India (Clarias magur, C. dussumieri and C. gariepinus) and their relationship with other representative clariids was studied in this work. Three species were sampled and together with 23 COI sequences from GenBank were used to reconstruct phylogenetic relationships in the family Clariidae. The study revealed two clades: one consisting of the African species with C. dussumieri, and the other of Asian species suggesting the prevalence of intra-continental diversification of catfishes. This study further revealed that the genus Clarias is monophyletic. For the COI gene, the interspecies genetic divergence ranged from 0.056 to 0.182. The mean genetic difference between C. dussumieri and other selected African species in this study is 12.1%. It was also observed that the morphological similarity of C. dussumieri and C. magur was not replicated in the genetic level. Clarias dussumieri was more close to African catfish C. gariepinus thus indicating the utility of COI phylogeny to identify the well-known African-Asian relationships within catfishes. The results also showed that C. magur and C. batrachus are genetically distinct from each other.

“…Hence a 1:1 ratio was strictly maintained in subsequent trials. Breeding trials were undertaken close to the onset of monsoon coinciding with first monsoonal showers-the identified spawning season in nature (Padmakumar et al 2010). In the breeding trials using ovaprim as inducing agents, even fully matured and gravid females failed to respond, although the fish exhibited vigorous sex play.…”

“…The species, once abundant in the rice polders, rivulets and temple ponds of Kerala, has now sharply declined as a result of increased use of pesticides and agrochemicals for intensive rice cultivation practices and land reclamation for construction (Padmakumar et al 2010;Shaji & Kumar 2016). Clarias dussumieri has very high consumer preference as a food fish with medicinal and nutraceutical properties due to the presence of high concentration of physiologically available iron, necessary for the synthesis of haemoglobin and essential amino acids (Padmakumar et al 2004).…”

Spawning occurred after 12-14 hr of injection and fertilized eggs hatched after 16:30hr. Larval rearing was carried out in cement cisterns and the larvae attained a mean size of 51.6±1.6mm in 60 days. Since brooders of this species have become extremely rare in nature, the present study on captive breeding by hormonal manipulation methods without sacrificing the male fishes, assumes significance for conserving this endemic species.

“…Clarias dussumieri Valenciennes, 1840, an air‐breathing catfish endemic to the Western Ghats in India, is categorized as near threatened in the Red List of the international union for conservation of nature (IUCN) (Abraham, ). The endemic catfish, C. dussumieri Valenciennes, 1840, popularly known as ‘naadan mushi’, was proposed as a candidate species aquaculture in Kerala, as it has high potential to grow to a maximum size of over 3 kg in nature (Padmakumar et al ., ). The population of C. dussumieri had been declining alarmingly over a short period, prompting a suggestion to revise the IUCN Red List status of C. dussumieri from near‐threatened to critically endangered (Aneesh et al ., ).…”

We describe a new cell line, Clarias dussumieri fin (ClDuF), from the caudal fin of C. dussumieri using the explant technique followed by cryopreservation. The cryopreserved CiDuF cells were validated for quality and other characteristics. They showed typical epithelial morphology in vitro and epithelial cells outgrew their fibroblast cells after the fifth passage. ClDuF cells had a characteristic sigmoid curve with population doubling in 24 h. Immunotyping of the ClDuF cells against cytokeratin suggested the epithelial lineage. Chromosome analysis showed normal diploid (2n = 50) numbers and the cells did not contain any contamination, including Mycoplasma and other microbes. Partial sequencing of fragments of mitochondrial 16s rRNA and COI genes of ClDuF confirmed that the cell line was initiated from C. dussumieri. Cells at the 10th and 25th passages had more than 80% and 70% viability in the culture, respectively, after 6 months of storage at LN2. These ClDuF cells were morphologically identical to the cells before freezing and the genetic resource of C. dussumieri was preserved. The species‐specific cells can serve as a valuable source for virus isolation, conservation and cloning of somatic cells.
