Owing to the spectacular colouration, fish species of the genus Rasboroides have a substantial economic value in the aquarium trade of the world. All the species of Rasboroides categorized as threatened fishes. The studies revealed that some species of the genus Rasboroides are having a stable population in the Southwestern wet zone of Sri Lanka. Osteology of these important species was studied and the findings further support the recently described or re-described species within the genus. One of the important characters of the genus is danionin notch which was only observed in R. pallidus. This character is always observed in related Cyprinid genera Devario. The presence of danionin notch in R. pallidus is mystifying since it is independently found in two different tribes of subfamily Danioninae. Further studies ought to reveal the status of this character within the Danioninae.

A TAXONOMIC STUDY ON THE SOUTH ASIAN CYPRINID GENERA HORADANDIA AND RASBOROIDES (OSTARIOPHYSI: CYPRINIDAE: DANIONINAE) AND EVALUATION OF THE PRESENT DISTRIBUTION PATTERN OF RASBOROIDES VATERIFLORIS PALLIDUS IN GIN RIVER2016 •
A taxonomic study was conducted to evaluate the systematic status of two cyprinid genera, Horadandia and Rasboroides. Comparison of all congeners of Horadandia and Rasboroides confirmed as two distinct genera in the tribe Rasborini by means of morphology (external morphology and osteology) and morphometry. Horadandia (i.e.brittani+atukorali) differs from Rasboroides (vaterifloris+nigromarginatus+pallidus+a new species) by a consistent set of autoapomorphies: (a) absence/ presence of bifurcation at posterior end of kinethmoid; (b) anterior boarder of cleithrum in ventral view either concave/ convex; (c) absence/ presence of sensory canals in infraorbital bones; (d) absence/ presence of a concavity before the coronoid process of dentary; (e) pharyngeal teeth surface ornamentation, either with grooves/ cusps; (f) absence/ presence of 6th hypural. In addition to those, following characters, which have been used to diagnose these two genera were repeated and confirmed in the present study: (a) absence/presence of a bowl-shaped depression on the supraethmoid; (b) attachment of Baudelot’s ligament on the dorsal part of the cleithrum, to distal end or not at the distal end; (c) number of rows of pharyngeal teeth either two/ three; and (d) lateral line absent or present (when present, incomplete). Comparisons of putative topotypes of Rasboroides vaterifloris with materials collected from several locations including the locations of Deraniyagala’s subspecies of Rasboroides in the southwestern wet zone quarter of Sri Lanka (including Rakwana hills) revealed that R. vaterifloris actually represents four different species. Present study uncovered, two subspecies of Rasboroides identified as distinct species and described a new species of Rasboroides as well. Horadandia atukorali brittani is resurrected as a distinct species. Thus, Horadandia atukorali, Rasboroides nigromarginatus and R. pallidus are three new additions to the endemic freshwater fish list of Sri Lanka. Rasboroides vaterifloris appears to be a relatively uncommon fish in Gilimale forest. Rasboroides nigromarginatus is restricted to the Atweltota (near Matugama), whereas R. pallidus has a stable population in the Bentara, Gin, Polatumodera and Nilwala rivers. The new species found from Walawe River is the first record of the genus from Walawe river. Horadandia atukorali is a widespread species in the low land (North-western, Western and Southern Provinces) areas of Sri Lanka, whereas Horadandia brittani is endemic to South India (Kottayam and Pondicherry areas). To investigate the physico-chemical parameters suitable for distribution of Rasboroides pallidus, five sites were selected in the Gin River, of which R. pallidus was recorded only from two sites (i.e., Kottawa and Kanneliya). Physico-chemical parameters of both Kottawa and Kanneliya were showed more or less similar values. Except Kosmulla (in the Sinharaja forest), the other locations in which R. pallidus was not observed were within secondary forests and/ or polluted. Kosmulla site was a torrent, but similar to the type locality of R. vaterifloris. Physico-chemical parameters of Kosmulla might not be favourable for Rasboroides. Results on the velocity (flow rate), substrate and depth were in accordance with the previous study of R. vaterifloris conducted at Ginigathhena (a locality in the Mahaweli River). Present study concludes that Rasboroides pallidus is a habitat specialist, confined to Kanneliya and Kottawa in the Gin River. With the onset of monsoon, breeding of Rasboroides pallidus was observed.

Osteological development of the vertebral column, paired, dorsal and anal fins in Rutilus caspicus, Pravdin (1927) (Teleostei: Cyprinidae)2015 •
Study of the osteological development in fishes is important from fisheries, biology and aquaculture points of views. It can be used as an early bio-indicator of non-optimal rearing conditions. The Caspian roach, Rutilus caspicus is a native cyprinid fish of the Caspian Sea that its artificial propagation has fulfilled in hatcheries to recruit its natural stocks. Hence, this study was conducted to provide early development of its vertebral column, paired and median fins from hatching up to 90-dph as basic biological information. For osteological examinations, the specimens were cleared and stained and a detailed description of the ontogeny of the post-cranial skeleton provided. The results showed that no osteological structure present at hatching. The first observed skeletal structure was the vertebral column followed by the pectoral fins, caudal fins and almost simultaneously dorsal, anal and pelvic fins

Comparative osteology of lotaks, Cyprinion kais and C. macrostomum (Cypriniformes, Cyprinidae), from Godarkhosh River, western Iran2013 •
The quantitative osteological study has been conducted on a Hillstream bottom feeder fish Crossocheilus latius latius. C. latius latius is a common hillstream fish of Snowfed Rivers of Alaknanda. The bones have been taken from different sized fishes ranged from 13 to 27 Cm in length and 39 to 132 gm in weight. The correlation is applied between Body Weight and the Weight of different disarticulated bones of C. latius latius. The correlation (r) is highly significant among the different parameter of body in relation to osteology which ranged from r = 0.952; P< 0.1 to r = 0.999; P< 0.1. Keywords: Articulated and disarticulated bones, Correlation coefficient, Crossocheilus latius latius, Quantitative osteological study

Osteocranium of Tor tambroides (Cypriniformes: Cyprinidae) from Tangse River, Aceh, Indonesia2020 •
Akmal Y, Zulfahmi I, Dhamayanti Y, Paujiah E. 2020. Osteocranium of Tor tambroides (Cypriniformes: Cyprinidae) from Tangse River, Aceh, Indonesia. Biodiversitas 21: 442-450. We report the first detailed descriptive osteocranium of keureling, Tor tambroides (Cypriniformes: Cyprinidae) collected from Tangse River, Indonesia. This study aimed to describe the cranium morphology of keureling (Tor tambroides). Keureling fish used in this study were obtained from the catch of fishers in the Tangse River, District of Pidie, Aceh Province, Indonesia. Stages of research include sample preparation, bone preparations, and identification of cranium nomenclature. For osteological examination, the cranium of the keureling prepared physically and chemically. Based on the results, the cranium of the keureling is divided into two major parts, namely the neurocranium and the facial bone,s including the branchial apparatus. The neurocranium is divided into (anterior to posterior) olfactory (ethmoid), orbital, otic, and occipital regions while the rest divided into oromandibular, opercular series, branchial arch, mandibular arch, and hyoid arch (suspensorium) regions. The neurocranium includes bones in the dermal series of the skull and endochondral bones protecting the brain. At the same time, branchiocranium are those located in the oromandibular part, opercular series, and branchial arch.
