Dive info

 

In this section Divewerkz would like to share with you information about popular dive destinations in this region, common fish species in the Asian Marine Life and some useful tips for bouancy, conserving air or equalization techniques. Below you will find an overview on how to identify fish in order to make your future dives even more rewarding.

Why ID fish?
To many divers identifying fish may be an overwhelming task. But, believe it or not, with the right approach, it’s fun and easy.

-Better dives
When you are able to recognize fishes you have a mental description of the dive. Remember those times when you get frustrated describing a fish and nobody seems to understand what you are talking about? Knowing the names of fishes helps communications with other divers and you get more out of the dive – and impress your buddy.

-Aid navigation
Certain fishes are territorial and when you recognize them they become the landmarks for your course of travel. Fishes such as clownfish and damselfishes live and often feed within a certain area.

-Safer diving
Knowing which fish is dangerous is obviously important. Scraps with fishes such as surgeonfish, stonefish or scorpionfish can leave you with serious injuries.

How to ID fish?

-Shapes
The first step to identifying fish is to put them into their family group. Classifying with shape and general features is the easiest way to identify the family they belong to.

-Size and special markings
Within the same family, some fishes look incredibly identical. If this is the case, take note of the size and confirm it with the size in Fish ID/Marine Life books. Also take note of specific features and/or markings on the fish. To do this it helps to learn the parts of the fish (see below) and jot down the markings observed on a slate.

-Depth and habitats
Fishes have distinct habitats. Some fishes favour deep waters whilst others stay within 20 metres from the surface. Some are primarily coral dwellers such as anthias, whereas fishes such as goatfish and gobies stay mainly on sandy bottoms.
