The most shocking part of the scientists’ projection is that by 2050, there will be more plastic swimming in the ocean than fish.

To make fish’s swimming more realistic, we need three joints between the trunk and the caudal fin. As actuators we have chosen of common modeling servos: small, powerful enough and easily controlled by a microcontroller.
The servos are ideal because with them you can manage the movement of a small shaft connecting all segments of the fish, varying at will the position, even a few degrees.
The fish body is divided into a central part and three parts, each of which moved by a servo. The caudal fin is made with plastic recycled from supermarket goods packages. with Fish Robotic Fish Artificial Swimming Robofish Shark Tank Ornaments Plastic Fake.

The premise behind the wind-up swimming fish is the idea that motion in water can be generated by simple back and forth movement, and the principles of magnetic attraction. The basic idea is that when wound, the fish would swim for a moderate period of time, in a relatively straight path. When semi-buoyant smaller fish are placed in the water as well, a child can wind and place the large fish in the water with the goal of attempting to devour one or more of the smaller fish. As the fish could be color-coded, so could children make a contest of trying to devour specific fish before the other, or attempt to devour the opponent's fish. Unfortunately, the children would have to wind the fish up after it stops, but this is true of any wind-up toy. The production cost of this particular toy would be relatively low. This is due to the vast availability of wind-up parts that could be used in the fish and the inexpensive nature of small, low strength magnets and plastics that can be used for such a toy. As these parts are relatively inexpensive (as seen in the price of wind-up toys currently), the production cost of this particular toy would be projected as being relatively low. The durability of this toy would also be relatively high. Since the casing would be made of plastics, and would protect the more delicate inner workings of the fish, the fish would be able to sustain a moderate level of abuse before ceasing to function properly. This is also true of the play environment. Since plastic is relatively hard to damage in water, proper use of this toy would make it even more durable. This is not to say that one well placed throw into a slab of concrete would not crack the fish and cause it to sink in water, but even then, the fish would be able to swim to some extent. As such, it is projected that the durability of this toy would be rather high. Safety would largely depend on the final production size of the toy itself. Were the smaller fish to be larger than the choking hazard size, the fish themselves would be relatively safe for play with very few sharp edges, and a durable plastic coating keeping smaller choking hazards inside the fish. However, there is still a risk that children could manage to break the toy and choke on the smaller pieces, but this can also be said of most toys. As such, this toy would be projected to be very safe for children to play with. The ideal age group would be 5-8. Old enough to wind and operate the toy, but young enough to not find it completely juvenile. Disturbingly, the researchers discovered that the presence of the plastic also changed the food preferences of the exposed fish. Larval perch that had access to microplastic particles only ate plastic, while completely ignoring their natural food source of free-swimming zooplankton. The researchers say there’s probably a chemical or physical cue emitted by the plastic that triggers a feeding response in the fish.
A recent study reveals that a European perch larvae exposed to high concentrations of microplastics have experienced stunted growth. Aside from this, the plastic pollution also affected their feeding habits. They no longer feed on free swimming zooplanktons in the ocean, which have always been the species natural source of food. Fish now eats plastic, further exposing them to the damaging effects of toxic chemicals.Robo Fish come with two X2 batteries already installed as well as two extra X2 batteries to keep your fish going, even after he peters out. They also come with a plastic stand to hold your Robo Fish when he’s not swimming.
