Pseudomystus siamensis

Heok Hee Ng, Jörg Freyhof, and J. W.Armbruster (2005) A New Species of Pseudomystus (Teleostei:Bagridae) from Central Vietnam. Copeia: December 2005, Vol. 2005, No. 4, pp.745-750.

A new species of bagrid catfish named Pseudomystus sobrinus was observed. P. sobrinusis different from P. siamensis in that it has “a slightly bulbous snout,shorter adipose-fin base and pectoral-fin spine”. (Source cited above).

Bagrid/bagridae catfish

Experiments on Pseudobagrus fulvidraco(yellowhead catfish/Korean bullhead) showed that the optimal diet for growthand effective protein utilization in fingerlings is 42% protein and 19% lipid. (Source)

Experiments on Mystus nemurus (AsianRed Tail Catfish) showed that types of lipids consumed by the fish (cod liveroil, corn oil, and crude palm oil) did not impact the growth performance of thefish. Fish that consumed lipids from refined, bleached and deodorized palmolein showed significantly higher growth rates. The article suggests that usingpalm oil in dietary formulas for M. nemurus and other catfish species may lowerthe cost of fish feeds (due to the oil’s widespread availability). (Source)

Madtoms, Noturus spp

Experiments on hatching Madtom (Noturus insignis) eggs found that theoptimal conditions were a high water temperature and agitation strong enough totumble eggs. The temperature was from 28-30 degrees C (~82-86 degrees F) andthe egg masses were kept in constant motion. These techniques for artificialegg hatching and propagation may assist in the recovery of this fish. Malemadtom fish was proven to be one of the least effective methods because of thetendency for the fish to cannibalize their eggs if the nest is disturbed at all,even if fed properly (this is especially true in captivity).
