Which of the following fish is a surface feeder?
They are a surface feeder that feeds on the water's surface. Explanation for incorrect options: Option A. Eels are creatures that live in seawater. As a result, they can only be found in shallow water in oceans. It can swim because of its ray-shaped fins. That has an elongated shape that can reach a length of 5cm.
Screw Feeders
Normally short in length, Screw Feeders are designed to regulate the volumetric rate of material flow from a hopper, bin or storage unit. The inlet is usually flooded with material ( load capacity) but by incorporating changes in the construction of the flighting (diameter, pitch, etc.) and the speed of the feeder screw, the material discharge can be …
Which of the following is called the surface feeder?
Solution. Verified by Toppr. Catla catla is the most common edible fish in India. They are called surface feeders as they consume foods from the surface of pond or water body. Rohus feed in the middle-zone of the pond, Mrigals and Common Carps are bottom feeders, and Grass Carps feed on the weeds, So, the correct answer is option A.
