N°1 | Brown Trout
The Brown Trout belongs to the Salmonidae family. According to the location, the adult size varies from 25 cm to 80 cm for 300 to 800 g. It lives for 3 to 6 years. The spawning period starts in October and end in January. The female can lay up to 4000 eggs. The fishing period is open from the second Saturday of March until the third Sunday of September.

Depending on its environment, the brown trout have a very variable color, but the brown trout, as its name shows, is rather brown with scattered black and red spots, depending on the spawners. It has a certain mimicry according to the bottom of its living spaces since the dominant brown will become a green dress if it lives close to the banks where yellow and even sometimes silvery white will mix. It has a "useless" adipose fin between the dorsal fin and the caudal fin. The head is tapered, strong and has a powerful jaw. Its back is a pretty black or night blue.

Castlebar - Fishing techniques Top fishing techniques
Top fishing techniques
N°1 | Fishing with bombette
Bombette fishing is a technique invented by Italian fishermen to fish for trout in lakes. Although this method of fishing is still relatively unknown to some people, it is becoming more and more common nowadays. It is even used for fishing carnivores (perch, pike, pike-perch, pike-perch...) Easy to implement and requiring little preparation time, this fishing technique is perfectly suited both to beginners wishing to learn trout fishing in water bodies, and to experienced fishermen wishing to take advantage of its many possibilities. But what does this technique really consist of? What equipment is suitable for this type of fishing? Here are some useful information that will help you start fishing with a bombette in good conditions.
N°2 | Tips on material to catch bass on plug from the shore
For each category of equipment, the items (four per category) will be classified from the cheapest to the most expensive. What we propose here is only a suggestion, you are free to use the material you want. Some parts of the equipment (weights, hooks, etc...) will not be mentioned in this article.
N°3 | Float fishing (plug)
Fishing can be a fun, sporting and beneficial activity. A thrill across the line, a beautiful specimen to go up, it's every fisherman's dream. Float fishing, or also plug fishing, is a fishing technique that can hit the mark if you know it well and master it.
N°4 | Tips on material for mullet fly fishing
Here are some articles that can help you choose the right equipment for fly fishing for mullet
N°5 | Lure fishing for Bass
When you do not know where to find bass, it’s better to fish from the surface and go deeper and deeper.
N°6 | Fishing squid with jig on board
The jig is a lure with a crown of hooks. Ideal for squid fishing, it can sometimes imitate the shape of fish, sometimes that of shrimp, be phosphorescent or bright, brightly colored or not. It requires little equipment and brings a lot of satisfaction thanks to the generally abundant catches, provided that you do not neglect any parameter in the choice of your posts and animations.
