AFRICAN TIGER FISH

genus Hydrocynus

UNDER COMPLETE RE-WRITE CHECK BACK IN 2012

INTRODUCTION

I've done little to no research on this fish, since it has not been readily available. You can check out various fishing web sites under the African Tiger Fish or genus name Hydrocynus and that should give you a lot of native habitat information.

OPEFE was recently sent 5 preserved African Tiger Fish juveniles. On March 22, 2000 OPEFE secured 2 live specimens of Hydrocynus vittatus. Most of these were sent to Oregon State University where Dr. Douglas Markle will be using them for his neo-tropical division students. The fish measured about 5-6 inches each and all were positively identified by Dr. Markle's student as H. vittatus.

Hydrocynus (or fish dogs, or fish tigers) are known strict ichthyophagous for their promptness and their voracity. All the fish belonging to this kind appreciably look the same and only an attentive examination makes it possible to differentiate them. They have a torpedo form, which they use to their advantage of nourishing itself, since they continuously chase their prey. The fish are generally silver plated and brilliant. The scales are marked with a dark spot, thus forming especially visible parallel stripes above the side line. According to certain species', these lines are more or less dark. The dorsal fin is inserted into the same level as the ventral fins or a little ahead. The mouth is armed with only one series of teeth, very developed and sharp, on each jaw. The eye is almost entirely covered with a fat eyelid.
