A well-fitting fish box in a lid boat is not just a storage tank, but a critical element of gear that depends on catch safety and swimming safety. Unlike buckets or simple bags, a specialty cage or caisson provides the necessary conditions to prevent premature spoilage of trophies even in hot weather. Modern models are equipped with aeration systems, reliable locks and ergonomic fasteners.
Choosing the right design directly affects the comfort of the angler and the life of the boat itself. A poor or improperly installed container can cause extraneous odors, damage the sides or even cause the center of gravity of the vessel to shift. In this article, we will discuss in detail the materials, design features and nuances of installation.
Consider both ready-made solutions from leading manufacturers and self-manufactured options that allow you to save your budget without losing functionality. fish-fish It will help you avoid common mistakes that beginners face when first equipping their boat.
Material selection criteria: plastic, metal or fabric
The first thing that fishers encounter when looking for a catch container is a variety of materials. Plastic boxes, often made from food-grade polyethylene or ABS plastic, are the most common choice: They are lightweight, corrosion-free and easy to wash, which is critical for hygiene in the confined space of the boat.
Metal cages made of stainless steel or aluminum are chosen by those who value durability above weight. However, the metal requires special care, since salt water or the aggressive environment of river bodies of water can provoke oxidation if the protective coating is damaged.
Cages made of special fishing capron or nylon provide perfect water exchange, but do not protect the catch from predators and do not retain temperature; they are only suitable for short-term storage of active fish that are planned to be released or cooked the same day.
- 🐟 Plastic. It is optimal for ice storage and long-term transportation, easy to clean.
- ⚓ Metal Maximum strength, but risk of damage to the boat and corrosion.
- 🌊 Grid. Better water circulation, but no thermal insulation and protection.
- 🛡️ Combined - plastic case with a mesh bottom for balance of properties.
⚠️ Warning: When choosing a metal cage, be sure to check the quality of the edge treatment. Any barb can pierce the side of the PVC boat when rolling, which will lead to an emergency on the water.
It is important to bear in mind that plastic It doesn't absorb odors, unlike some technical polymers. If you plan to store fish with ice, make sure the casing material withstands low temperatures and doesn't become brittle in the cold.
Design features of the cover and locking system
The lid is a key element that turns a regular container into a full-fledged fish box into a boat with a lid, and it has several functions: it prevents water from splashing out when turbulent, keeps the temperature regime inside, and blocks foreign objects or animals from accessing the catch.
Locking systems range from simple latches to complex sealed locks. For fishing in motion when the boat glides, it is critical to have reliable locks that do not open spontaneously from vibration. A rubber seal around the perimeter of the lid creates a thermos effect, allowing you to keep the cold for hours.
Some models have transparent windows or removable sections, which allow you to visually monitor the status of the catch without opening the main lid, which is especially useful if you use the cage as a live fishery, where it is important to monitor the activity of the fish.
Why is the sealed cap important not only for water?
The sealed lid prevents not only water from leaking out, but also the spread of a specific fishy odor throughout the boat, and it protects the contents from rain, which can wash away mucus from the fish or, conversely, bring dirt from the shore.
And if you look at the lid mounting loops, metal loops are more reliable than plastic ones, but they can rust. through-axis stainless steel that runs through the body and cover, ensuring a long service life of the mechanism.
Ventilation and preservation of catch: live fish or caisson
The main difference between a caisson and a fishbasket is the water exchange system, so if your goal is to keep the fish alive, there's not enough static water inside the box, you need constant circulation, so you need to oxygenate the water.
There are two basic approaches to ventilation: One is the use of flow cages, where water circulates freely through a perforation or net by moving the boat; the other is the installation of autonomous aeration systems with compressors powered by the boat's battery.
For passive storage (cooling), thermal insulation is important, and the walls of a quality box should be double, with a layer of air or polyurethane foam, which allows the minimum amount of ice to be used to keep the catch fresh throughout the day.
| Type of container | Water circulation | Temperature retention | Best application |
|---|---|---|---|
| Grid-garden | Natural (100%) | Missing. | Short-term storage of live fish |
| Plastic caisson | Missing. | High (thermo-insulation) | Transportation, storage with ice |
| Pomp-fisher | Forced. | Average | Long-term maintenance of live fish |
| A box with perforations | Natural (when moving) | Low. | Active fishing on the move |
When using autonomous aeration, it is important to correctly calculate the power of the compressor. Too strong aeration can injure fish, and too weak aeration will not ensure survival. The optimal is to create a light bubbling that evenly distributes the bubbles.
Installation and fastening of the box in the boat
Safety is the number one priority when placing any cargo in a boat. A fish box in a lid boat, especially full of water and catch, can weigh tens of kilograms. Shifting such cargo at high speed or in a sharp maneuver can lead to a boat tipping over.
The fastening should be rigid and reliable. For PVC inflatable boats, fastex sling systems or special platforms glued to cylinders are ideal. For metal boats (Kandak, Crimea), bolt joints can be used, but with mandatory sealing of holes.
☑️ Checklist of safe installation
Place the container closer to the diametric axis (DP) and as low as possible, so as not to raise the center of gravity. The best place is between the seats (banks) or in the bow, if there is a platform.
⚠️ Warning: Never leave the box unattached, even if you just switched sides. A wave or gust of wind can move a heavy capacity, damaging gear or causing injury.
Use it. rattle-string Or carabiners that can be easily unbuttoned with one hand in an emergency but hold the load securely when shaking, and check the mounting points regularly, as ultraviolet light and water destroy synthetic materials over time.
Making a box for fish yourself
Making a homemade product is a great way to get exactly what you need and save money, and the most affordable option is to use food plastic canisters or 20-40 litre barrels, which already have the necessary tightness and chemical inertia.
The fabrication will require a drill with a crown to create ventilation holes (if you need a duct), a hacksaw to cut the hatch and a loop for the cover. As a seal, you can use a car camera or a special rubber tape.
If you make a netting cage, you'd better weld it out of rebars or use plastic pipes, tighten the net so it doesn't hit the side of the boat, and you need to treat all the metal elements with corrosion-resistant paint.
Use old plastic canisters made from edible oil or juice, which are ideal for the case, they are durable, lightweight and do not require additional processing before use.
When designing a drawing, be sure to lay a safety margin. The water is heavy: 1 liter weighs 1 kg. A 30 liter box with water and fish will pull 35-40 kg. The design must withstand this weight plus dynamic loads when hitting a wave.
Care, cleaning and storage of equipment
Fish odor and mucus are the main enemies of any equipment. After each fishing, the box must be thoroughly washed with fresh water, even if you have been swimming in the sea, salt residue accelerates corrosive parts, and organic residues become a source of bacteria.
For disinfection, you can use a weak solution of vinegar or special sprays to remove the smell. It is not recommended to use aggressive chemicals (chlorine), as its vapors are harmful to breathing in a confined space, and the residue can poison the next catch.
Store containers should be disassembled or with the lid open, in a dry and ventilated place. Plastic in the sun can "swim" or lose color, and the rubber of seals - dry. Metal cages are better lubricated with silicone grease before wintering.
How to quickly remove the strong smell of fish from plastic?
Put some dry mustard or soda inside a drawer, pour some warm water and leave it for a few hours, then rinse thoroughly. Freezing is also good, because if you leave the drawer in the cold for a day, the smell will almost disappear.
Regular examination of the condition sealer If the rubber becomes hard or cracked, it needs to be replaced or the tightness will be broken.
Frequently Asked Questions (FAQ)
Can I use a regular freezer as a fish box?
You can only use a household freezer on a boat with a powerful inverter and generator, which is rarely justified. A conventional stall is not sealed to water outside and is not designed for constant tilting. It is better to buy a specialized thermal container.
What is the best size for a single boat?
For a single boat, the optimal volume is 20-30 liters. A larger volume will create problems with the positioning and stability of the vessel, and a smaller one will require too frequent unloading of the catch.
How to prevent freezing of water in the cage in winter?
It is difficult to completely prevent freezing in the hole, it is recommended to use crates with a lid and insulation, as well as periodically break the ice. For live fish, it is better to use heated containers in winter or keep them warm, lowering them into the water only while fishing.
Is new plastic harmful to fish?
Technical plastic can release toxins that kill fish, use only containers labeled "Food plastic" or glass and fork icons, and if the box has a strong chemical smell, soak it in the sun and rinse it several times before first use.
Proper care of the cage increases its life by 2-3 times and ensures that your catch will always be fresh and of high quality.
