BUSHYMOUTH CATFISH

The bushymouth catfish (Ancistrus dolichopterus) is a species of armoured catfish native to Brazil and Guyana. It is found in the middle Amazon basin and in the basins of the Rio Negro, the lower Trombetas, the Tefé, the Madeira and the Tapajós Rivers. This species grows to a length of about 12 centimetres. This species is found in the aquarium trade.

These catfish are usually a dark spotted colour, but there are albino, gold-coloured and the red rarer ones shown here. Ancistrus Super red is a variety with an orange colour, turning red. The male has appendages on the head, which give the sensation of being horns, while the females have only thin tentacles. They are rarely seen for sale, and the one photographed here was in an aquarium.

FISH LADDER

Darebin Creek fish ladder in the Darebin Parklands in Alphington. A fish ladder, also known as a fishway, fish pass, fish steps, or fish cannon, is a structure on or around artificial and natural barriers (such as dams, locks and waterfalls) to facilitate diadromous fishes' natural migration as well as movements of potamodromous species.

Most fish ladders enable fish to pass around the barriers by swimming and leaping up a series of relatively low steps (hence the term ladder) into the waters on the other side. The velocity of water falling over the steps has to be great enough to attract the fish to the ladder, but it cannot be so great that it washes fish back downstream or exhausts them to the point of inability to continue their journey upriver.

Carried out by Melbourne Water, the $350,000 project in Darebin Creek involved installing a series of carefully designed rock works placed downstream of the structure in Darebin Parklands. This ‘rock ramp fishway’ allows water to cascade through the structure forming eddies that act as a refuge for fish so they can move freely through the waterway.

The design targets fish species that migrate from saltwater to freshwater environments to complete their life cycle including Common Galaxias and Short Finned Eel. The fish ladder was constructed with imported locally sourced rock. The project was constructed on site where materials were matched to complement the natural waterway and the environment.

FISH DINNER?

These fish are part of the décor in a restaurant in Melbourne's Southbank entertainment complex. The obvious question for all passers-by is: "Are they just decorative or part of the fresh fish menu?" Not a good question to ask, especially if the fish look at the camera and smile obligingly!

POND LIFE

Today was a sunny and fine Winter's day so I went for a walk in the Parklands. There was a water quality test and pond life tally going on, so I stopped and said hello to the person in charge who explained what was being done and showed me some pond life critters.
