Results for “bycatch”

This species, which may also be referred to by the alternative vernacular names 'spiny catfish', 'painted talking catfish' or 'chocolate raphael', isn't particularly common in the trade and most often exported only as bycatch among shipments of Platydoras armatulus. It appears very similar to the congener A. spinosissimus with the most useful external distinguishing character being the presence of pale blotches on the dorsal surface, between the dorsal and caud...

This species, which may also be referred to by the alternative vernacular names 'spiny catfish', 'painted talking catfish' or 'chocolate raphael', isn't particularly common in the trade and most often exported only as bycatch among shipments of Platydoras armatulus. It appears very similar to A. cataphractus with the most useful external distinguishing character being the presence of pale blotches on the dorsal surface, between the dorsal and caudal fins, in....

The German term 'breitbinden' translates literally as "broad-banded" and refers to the uniformly broad suborbital stripe seen in males of this 'species' which remains undescribed despite being known in the aquarium hobby for several decades. It's often imported as bycatch among shipments of wild-collected A. iniridae. Some of the populations have also been assigned th...

This species is not often seen in the aquarium hobby but occasionally exported as bycatch among shipments of other fishes. It was described as a subspecies of the closely-related 'P.' binotatus but is currently considered distinct on a tentative basis as per Ng and Tan (1999) who stated it is 'likely' that the two represent extreme colour forms of a single, variably-patterned species.

This species is very rare in the trade and is normally imported only as bycatch among shipments of other fishes. It can be told apart from its well-known congener B. dorsiocellata by a combination of characters as follows: lateral line complete (25-30 pored scales vs. 4-9); more scales in the lateral row (29-32 vs. 25-27); larger adult siz...

This species is not traded for aquaria but is occasionally exported as bycatch among shipments of other species. It differs from congeners in that the outermost row of teeth are not enlarged plus the interorbital space and cheek below eye are not scaled. Butis spp. are largely nocturnal ambush predators with cryptic...

In the aquarium trade this species may also be seen on sale as 'skinhead barb'. As with others in the genus little has been written regarding its captive care but it makes a peaceful and unusual addition to larger aquaria. The best way of obtaining it may be to keep an eye on shipments of wild fishes from Indochina and the Greater Sunda Islands as it's rarely imported in large numbers and most often arrives as bycatch.

This species is occasionally available in the aquarium trade, although usually as bycatch among shipments of other fishes. It is sometimes traded as H. sp. 'Araguaia red', H. sp. 'Araguaia' or 'Schultz's tetra'.

This species is not traded often but may occasionally be exported as bycatch among shipments of other species. It can be distinguished from congeners by the following combination of characters: presence of large, exposed scales on top of head; dorsal-fin origin posterior to pelvic-fin origin; moderate to small size (to 29 mm SL); caudal-fin emarginate and with dark reticulations; caudal-fin lobes with dark, elongated spots along upper and lower edges.

This species is not traded often but is occasionally available as bycatch among shipments of other species. It can be told apart from congeners most easily by the prominent, dorsally-orientated, roughly semi-circular lamina circularis in males, a feature unique within the genus. Other distinguishing characters include a combination of: forked caudal-fin; relatively small adult size; dark <-shaped mark at the base of the caudal-fin; a black spot at the base of branched caudal-fin rays 3-5.

This species is almost unheard of in the hobby with the specimen pictured above the only one we're aware of. It was imported into the United Kingdom in late 2011 as bycatch among a shipment of mastacembelid eels from northern India, and the identification was subsequently confirmed by Justin Havird, senior author of the most recent revision of the genus.

This species is not traded often but may be available occasionally bycatch among shipments of other species. It can be told apart from congeners most easily by the following combination of characters: truncate caudal-fin; scaleless patch on top of head; caudal-fin with reticulated patterning, sometimes appearing as a series of thin vertical bars; body reddish brown with darker markings; 3-7 predorsal and 3-6 postdorsal thin, transverse dark bars running across the dorsal surface; relatively deep...

The genus Leptodoras currently contains 10 species, none of which are particularly well known in the hobby. There is little published information regarding the genus, and its members are seldom exported for the aquatic trade. L. linnelli is no exception, usually only turning up as bycatch among shipments of other species such as Opsodoras leporhinus or Hassar orestis. According to Fishbase, it can be distinguished from all other members of the genus except L. acipenserinus by the presence of...

L. disparis is sometimes available as bycatch among shipments of other species such as Rhinogobius duospilus but also appears on trade lists under the fictitious scientific name 'Homaloptera hoffmani'. It can be told apart from similar-looking members of the genus Formosania by its noticeably shorter barbels and from Vanmanenia spp. by the fact that the rostral fold is not lobed and the mouth is relatively small (25% head width. In addition the lower lip in Liniparhomaloptera is not divided and has a flat, papillated edge.

This species is occasionally marketed as 'Burmese Rainbow Barb' in the ornamental trade. others may have been exported in small numbers or as bycatch among shipments of other species. It was referred to as Mystacoleucus marginatus for decades, but that name is a simultaneous subjective synonym of M. obtusirostris following Kottelat (2013).

This species is poorly-known in the aquarium hobby but is sometimes exported as bycatch among shipments of other species, especially Nannostomus beckfordi to which it appears quite similar. The easiest way to tell the two apart is that N. grandis lacks pale white or bluish tips to the ventral fins. It can be further distinguished from all congeners by the following combination of characters: body size up to 46.2 mm, the largest in the genus; bo...

This species is quite rare in the aquarium hobby and is not often available in numbers, more often being exported as bycatch among shipments of the congener N. eques. Following Weitzman and Cobb (1975) it can be diagnosed by the following combin...

This species is also known as 'Marilyn's pencilfish'. It's rarely traded in numbers and more often seen as bycatch among shipments of other species, particularly Paracheirodon axelrodi. It can be identified by the following combination of characters: three dark lateral stripes (sometimes referred to as primary, secondary, and tertiary); nocturnal oblique bars relatively narrow, with the anterior bar reaching, but not extending past, the anterior base of the dorsal-fi...

Ther are currently five described species of Nemadoras (N. elongatus, N. hemipeltis, N. humeralis, N. leporhinus and N. trimaculatus). All are rare in the hobby, although this species is the one most commonly seen. As well as the occasional import, it sometimes shows up as bycatch among batches of similar-looking Hassar or Hemidoras species. Of these, it is most often confused with Hemidoras stenopeltis. These two can be easily told apart as N. leporhinus has a clearwith a dark patch at the base...

Infrequently encountered in the aquarium trade, most often as bycatch among shipments of similar-looking congeners. It's included in the P. kuhlii group of closely-related species within the genus, and can be distinguished from other members by...
