“…Management units justify management of population within species separately due to genetic differentiation ( Robalo et al, 2021 ). Morphological variation between populations together with molecular data ( Camelier et al, 2018 ; Ukenye, Taiwo & Anyanwu, 2019 ) can play an important role in understanding variation. Phenotyping research on fish species to define intra-specific diversity is still at infancy and has not been widely applied for most of the aquaculture and harvested species.…”

Chitala chitala (Hamilton, 1822) is an economically important food fish species occurring throughout Indian rivers, which also has ornamental value. This study focuses on morphological variations in C. chitala from seven river basins across India namely; Son, Tons, Ken, Brahmaputra, Ganga, Gomti and Gandak. A truss network was constructed by interconnecting nine landmarks to generate 36 morphometric variables extracted from digital images of specimens sampled from the study locations. Transformed truss measurements were subjected to principal component analysis (PCA), canonical discriminant function analysis (CDFA) and discriminant analyses of principal components (DAPC). DAPC function coefficients performed much better in capturing the variation pattern and discrimination between the rivers which was not achieved using CDFA. Eight truss variables were identified with significant and highest loading for truss variables on principal components and coefficients on discriminant function from DAPC contributing to maximum variation between the rivers. Performance graph and functional distribution of identified truss variables clearly indicated distinction between the rivers. Thin plate spline analysis and procrustes shape analysis further showed the variation in morphology between specimens across the rivers. The significant parameters differentiating specimens from different rivers were linked to dorsal fin origin, the base of the pectoral fin and the perpendicular point on the anal fin from the dorsal fin origin. Variation in the hydrodynamics of the rivers studied might be possibly affecting the fin kinematics and consequently leading to adaption seen as phenotypic variation in C. chitala. The results showcased in the present study shall help in better understanding of intra-specific diversity which is significant for management and conservation of a species.

“…Nowadays, still it is frequently used for the evaluation of genetic diversity, identification and classification of aquatic animals, and population differentiation. Worldwide, it is in practice for segregating fish species (Guan et al, 2017; Ukenye et al, 2019). Morphological methods are generally based on body shape, number, size, colour, and pattern of scales, fins number and position; fin rays number and form, as well as measurements of several body parts (Teletchea, 2009).…”

Current study identified the rohu–catla intergeneric hybrids produced from reciprocal crosses at fingerling stage and attempted to find relationship with parent species, Catla (Labeo catla) and rohu (Labeo rohita) through traditional morphological and meristic approaches and a genetic marker, cytochrome C Oxidase I (CO1). Phenotypically, both hybrids (RC, L. rohita♀, and CR, L. catla♀) were intermediate in most of the traits, while some traits resemble their mother species. For accurate identification and phylogenetic relationship of all cross‐types (RR, CC, CR and RC), DNA barcoding by mitochondria COX 1 was also conducted. The constructed Neighbour‐Joining (NJ) tree (K2P) based on COI gene sequence analysis categorized all four crosses into two genetically distant groups. Each hybrid showed an identical phylogenetic relationship with the mother species, that is CR hybrids showed the minimum distance with L. catla, and RC hybrid showed the minimum distance with L. rohita. Moreover, the genetic distance between L. catla and RC hybrid was higher than between L. rohita and RC hybrid.

“…Tilapia guineensis, a typical estuarine cichlid species on Africa's West Coast, is an important fish species due to its enormous contribution to many African countries' nutritional, growth, and development needs. It possesses good aquaculture, economic, and dietary qualities, especially in terms of the protein nutrition of West Africans [9].…”

Aims: This work evaluates the nutritional quality of Clarias gariepinus and Tilapia guineensis fishes from River Doma in Nasarawa State, Nigeria. Study Design: African catfish (Clarias gariepinus) and tilapia (Tilapia guineensis) contribute enormously to the developing nation's nutritional, growth, and development needs, especially in terms of high protein retention in the human body. Methodology: Oven-dried Clarias gariepinus and Tilapia guineensis were analyzed using standard analytical techniques for proximate, mineral and amino acids compositions. Results: The respective proximate values (g/100 g sample dry weight) of Clarias gariepinus and Tilapia guineensis were high in crude protein (48.33 and 67.82) and crude fat (26.11 and 14.83) but low in crude fibre (3.22 and 3.91) and moisture (0.23 and 0.33). The calculated fatty acids and metabolizable energy for the two fish samples were (20.89 and 11.86 %) and (2004.98 and 1799.48 KJ/100 g), respectively. The most abundant minerals in the samples were potassium (321.72 and 364.23 mg/100 g) and phosphorus (210.54 and 213.74 mg/100 g), whereas manganese, iron, and copper were of low concentration (< 0.5 mg/100 g). Leucine, phenylalanine, and lysine were the most abundant essential amino acids in both samples. At the same time, glutamic and aspartic acids together with arginine account for more than 35 % of total amino acids in each of the investigated samples. Total essential amino acids (TEAA) with histidine and total sulphur amino acids (TSAA) were (33.10 and 2.54 g/100 g cp) for Clarias gariepinus and (36.18 and 2.92 g/100 g cp) for Tilapia quineensis, respectively. Meanwhile, valine and lysine were the first and second limiting amino acids in this study's samples, respectively. Conclusion: The fish samples were found to be good sources of quality proteins and both have the functional and essential amino acids.
