How To Identify Quality Fingerlings

A fingerling is a small fish that has grown to the size of a finger. They are popularly sold across fish rearing farmers because they are best used for the commercial production of fish. That is why, when buying a fingerling from a nursery, it is essential to look out for the best as this could affect your turnover.

It is very important for a fish farmer to carefully select the fingerlings that are to be brought into his farm. Quality fingerlings are as important to the fish farmer as quality seedlings are to the crop farmer. That’s because both have a direct bearing on the final harvest. Not having quality fingerlings could turn out to be a waste of the resources used in its purchase because they might eventually die off in the end, or not produce fish big enough to be sold at a good price.

So, are you a fish farmer working towards a bountiful fish output? Check the quality of your fingerlings with these:


To know if the fry to be purchased is of a good quality, check if they are of the same size. Fingerlings also known as fry should be carefully observed to ensure that they are of the same size. Fingerlings of the same size often tend to grow appropriately, yielding good profit. Also, it enables the farmer to properly plan towards harvest as he/she can forecast the growth of the fingerling.


There is a size appropriate to the age of a fingerling. Those that look too small or too big for their age might not be a good quality fry and should be avoided, as they might not be good for fish production. The inappropriateness of their size should tell that there is an underlying problem with them. Always carefully check that their sizes are appropriate for their age.

Fish type

Are they of the same fish type? You might be purchasing poor quality fingerlings if they are of different fish types. Avoid selecting fingerlings that are of different types. Choose the appropriate specie for the set you want to buy so that it would be easier for you to group them in the farm and attend to them according to their types.


The fingerlings should be of the same age. Purchasing fingerlings of different ages as a set would lead to an uneven growth of the fingerling, with some overshadowing the growth of the other in the fight for survival. It is not good practice to groom fish of different ages in the same nursery. Care should be given according to their ages.


If it seems like the fingerling is diseased or has any form of injury or deformity, you might want to leave it for more healthy ones. A diseased fingerling could pose a health risk to other fishes in the farm. Good quality fingerlings will have a form that is free of diseases, injury or any form of deformity that could lead to a loss.

Whether you get good or poor quality fingerlings, proper feeding and hygiene practices are essential to having a good harvest. Use only products that provide the best nutrition for your fish. With Vital feed, the right nutrition for your farm is absolutely guaranteed.
