Grouper Fishing and Techniques

Grouper fish
Groupers ranging in length from 60 cm to 120 cm are found weighing 30-50 kg. In the Caribbean, on the South Atlantic coast, there are very large breeds weighing between 120-300kg. It is an extremely strong fish, which is one of the biggest prey of underwater sports.

Grouper fish live in stony and cavernous places. Groupers approaching the shore in summer retreat to their cliffs and cavities in 300-400 meters of water in winter. Their skin is thick and hard. Its body is dark gray or brown with yellowish spots on it. The belly is lighter brown. Its teeth resemble a brush, the inside of its mouth is orange.

 

Grouper fishing, while the boat is anchored, is done by pulling on the back with a thick lug gear or with a double-eye sounder, when the boat is in motion, with a bottom drag team, with an artificial fish, or with an artificial petticoat. It can also be fished by drop or net.

The main baits used in the zip and double-eye sounder sets are large shrimp, whole cuttlefish, octopus piece,  and larch cut into half-eyes. As in every hunt, the freshness of the bait provides more positive results.

The grouper has a very strong jaw. When he jumps on the fishing line, he wants to grab the bait and run quickly towards his stone. If he throws the leash and resists a little and can be pulled into the boat for 5-8 fathoms without giving any opportunity to this movement, he will be helpless because he has moved away from his surroundings. Otherwise, if there is a gap when he grabs the bait, he quickly enters the cavity between the rocks and inflates the head part, and resists not coming out. Under these conditions, it is not possible to remove the fish from the stone. It is said that in the face of such a situation in grouper fishing, fishermen put bluestone and sounder in a small cloth bag and lower it into the cavity where the grouper enters, and with the help of melted bluestone, the fish let itself out of the stone. When approaching the boat using fish, it is taken to the boat with a very large gaff or by inserting the fingers into the eye sockets and holding it from there. 

The point that the amateur fisherman should pay attention to is that he does not put his hand inside the fish’s gill. Since the grouper’s giggles and opercula edge are razor-sharp, the hand is suddenly cut off and drenched in blood.

 

 

Hunting: Two types of gear is used in fishing while the boat is on the anchor:

1. Fishing Tackle The fishing line, 100 fathoms long, 1.00mm or 1.20mm, is wrapped around a butterfly (cork), and its free end is tied to a very strong 4cm swivel. It may give better results if the line is light green or yellow in color and hard. After the free end of the fishing line is attached to the swivel, 1-fathom length 1.00mm or 0.80mm body is attached to the empty ring. The other end of the body is connected to a swivel of the swivel clamp with a weight of 80-90gr on both sides. A 1.5 fathom long 0.80mm or 0.70mm thick fishing line is attached to the empty eye of the other swivel as a shackle. A lug with a weight of 40-50gr and a 9/0 needle are attached to the tip of the shackle. This lure is the same one used in toric hunting.

When the bearing is taken and the hunting area is reached, the iron is thrown further than the hunting area. The purpose of this is that when the fishing line is put into the water, the lure, which is dragged by the water, reaches exactly above the hunting area. After the bottom is found, it is checked once again whether the hunting ground is stony or not when the pinch hits the bottom. If the bottom is rocky, the fishing line is taken 3 fathoms up. In this case, the bait will float 1.5 fathoms above the bottom. Without losing this distance, the fish is expected by pulling the fishing line from time to time and leaving it a little bit.

 

2. Double-Eye Sounder Set, 100 fathoms long, 1.00mm or 0.90mm thick fishing line, which constitutes the fishing line of the set, is wrapped around the cork, and its free end is tied to a 4cm swivel. A fishing line with a length of 1 fathom and 0.80 mm is attached to the empty ring of the swivel. After the free end of the body is attached to another 4cm swivel, an additional size 1.5 fathoms long and 0.80mm is connected to the empty ring of the swivel. The other end of the additional body is attached to the empty eye of a double-eyed sounder weighing 90gr, and a 0.70mm thick and 1.5 fathom-long fishing line is attached to the other eye of the sounder. A 9/0 steel needle is attached to the head end of the shackle and the set is completed.

After arriving at the hunting area and anchoring, the fishing rod is put into the water and the sounder is expected to find the bottom. After finding the bottom of the sounder, the fishing line is taken up 2,5 fathoms and the fish is expected.

Two types of teams are used in the grouper month when the boat is in motion:

Grouper Hunting with Bottom Friction:
This team is almost the same as the team used in the fishing of fish such as dengue and leer. Therefore, it is possible to catch this type of fish while using it for grouper. While navigating with the motor against the waters with a very heavy road, the sounder of the team should be used as much as possible, keeping it at the apical, not hitting the stony bottom, and not getting stuck in the relations.

The hunting ground is rocky, stony, and cavernous creeks that deepen suddenly. The user of the engine sometimes helps his friend using the fishing rod by giving way to the engine at idle and sometimes at the engine. Hunting at dawn and sunset is more productive. If desired, the end of the set can be attached to the number 4 French spoon, which carries two bare needles or triple needles.

Single or double bare-needle archipelago baits should be fitted to cover the needles well. Whole cuttlebone, large pieces of octopus, and half-eye-cut fish are used in this set.

When it comes to the hunting area, the baited shackle is released into the sea, and when it comes to the part where the triple swivel and sounder are located, this part is thrown forward slightly to prevent the shackle from wrapping around the triple swivel. The fishing line is slowly lowered to the bottom and the sounder is expected to touch the bottom, and the sounder is left in the apical and rubbed to the bottom, and the hunting area is traveled very heavily.
At least 10-15 fathoms of fishing line is milked from the fishing line to the boat as it may want away as soon as the fish is caught.

It is necessary not to wind the fishing line during the hunt. In the prepared set, there is a 3 cm swivel on the sounder. This allows the line connected to the sounder to take its gamut, and it allows it to come out easily if the sounder is caught between the stones. As soon as the fish jumps into the bait and grabs it, it vents the sounder. First, a gap in the fishing line and then a hard hit is felt.

Grouper is a fish that grabs its bait and escapes to its stone in terms of character. Without causing this movement, it is necessary to immediately throw a very strong leash and quickly pull the fishing line 5-6 fathoms towards the boat. In the meantime, the person using the engine turns towards the fish, idling the engine and allows his friend to pull the fish more comfortably into the boat. If necessary, it can start the engine and go on top of it. When the fish has approached the boat, it is taken in with a very large gaff or by inserting the thumb and forefinger into its eyes and pressing it.

Making of the Team: After 100 fathoms of 0.80mm thick fishing line is wrapped around the butterfly, a 3cm swivel is tied to its free end. A 0.70mm body with a length of 2 fathoms is attached to the other eye of the swivel. The other end of the body is connected to the first eye of the 4 cm triple swivel. After being attached to the opposite eye of the triple swivel on a 0.80mm, 1.5-fathom long line, a 3cm swivel is attached to the free end of the line, a short fishing line is tied to the other end of this swivel and the end is secured. A sounder weighing 160-200gr is attached to this case. After connecting a 0.60mm line with a length of 2 fathoms to the third eye of the swivel, the free end of the line is attached to a 3cm swivel and a 0.60mm shackle with a length of 4 fathoms is attached to the empty ring of this swivel. 

A 9/0 bare needle is attached to the tip of the mole.

The back can be prepared with different weights, different live and artificial feeds. The important thing is that the depth of the waters with a stony bottom, the cruising speed of the motor and the path it follows, and the amateur fisherman’s knowledge of the beaches and the area where the stonefish he will hunt are nesting. If traveling from many shores, the nip is reduced, if navigating in deeper waters, the gear is weighted by adding nip, and the artificial bait is allowed to travel deeper.

From the first swivel, 30 fathoms of fishing line are released into the water from the fishing line and if there is a snag on the bottom, the fishing line is taken in for 5 fathoms and the motor is given some speed. Taking into account that very large fish can jump, the fishing line part of the team is thickened as 1.00mm, the additional sizes as 0.80mm, and the shackle section as 0.70mm.

In this type of team, the fishing lines and swivels must be very strong, the knots must be firmly seated and fixed on the fishing line by inserting a matchstick into the holes of the clamps and breaking it from the bottom.

Rapala brand artificial fish comes first among the artificial baits used on the back. These are made of balsa wood as a single, double, or three-piece, and they carry two or three triple needles at the bottom and bottom of the diving spoon or swimming spoon.

Its colors are yellow-red, green-silver, blue-silver (it has stripes resembling a sledgehammer), silver color. In addition to these single, double or three-piece artificial fish, the back is also used in artificial baits made of plastic, with various colors, double or single needles, in the form of inserts. Making the Kit: After 120 fathoms of 0.80mm fishing line are wrapped around a butterfly (cork), the tip is tied to a 3cm swivel. After connecting a 0.60mm fishing line with a length of 1 fathom to the empty eye of the swivel, the empty end is clamped with a weight of 70gr. The pinching is fixed by inserting a matchstick through its two holes in the middle of the 1-fat line, and this process is performed six more times with one fathoming line and pinching in the middle. 

The aim is to add seven nip bodies of 490gr at equal intervals to the fishing line. After attaching 2 fathoms of 0.60mm fishing line to the empty eye of the swivel of the last additional size, the end of this line is tied to a 3cm swivel. A shackle with a length of 0.60 and 5.5 fathoms is attached to the empty eye of the swivel and knotted directly to the spoon part extending from the mouth of the artificial fish, without a swivel. If the bait is artificial ink and there is a swivel at the end of the eye part, it is tied to it.
Jigging
You can also catch grouper fish by the jigging method. The area you are in must be rocky. Due to the largemouth of the grouper, jigs between 15-30 cm will give the best results.
