THE ORIGINS OF FISHERIES
Undoubtedly the man who lived on the land, in remote prehistoric times, had the opportunity to earn his food by simply collecting the spontaneous products of nature, then, later, he directed his attention to other prey animals. They could therefore go unnoticed, its craving for food, aquatic organisms, both freshwater and saltwater and, in principle, of course, he turned to catch those who could do with your hands without the need for special tools. Aquatic animals that laden for the first meal of the ancient man was almost certainly the crustaceans and molluscs; later, it is assumed, the man address the capture of fish, had to devote to this business initially with the aid of bare hands or with the block in certain areas of shallow water and restricted escape routes for animals that managed to trap. Another system, used for small fish, could be that the poisoning of water blocked by dams, or even the turbidity of the same that allowed abundant catches. Then the man began to use the weapons he needed the land for the hunting of terrestrial animals, For example, the arc, stick, spear, sharp stones etc. by such means he hit the fish made him unable to escape or to defend themselves and then captured by hand. Whether you catch fish in waters specifically blocked, but to other marine species whose habitat was farther from the shore, led the man to organize in the community, can not alone achieve those activities that could, with the help of many individuals procure large quantities of food. This leads to the discovery of those tools that, as we shall see, even in rough form to allow people to capture those marine animals which otherwise, with bare hands or weapons for hunting land or other devices, could never get hold of.
Bertavelli: They are tools made of netting fixed to one of the plastic consists of rooms designed in the shape of the cone inside the other one whose operation is similar to that of the pots: the kind of opening it allows the fish to enter , allowing it to move only inward trapping. When not in fishing may be closed accordion very little space. The Bertavelli are used in all areas of the lagoon in Italy and coastal ponds in Sardinia, to catch eels, sea bass, sea bream and mullet.
a trammel net: The net to trammel net consists of three sheets of the vertical networks such as the median is thin and small-meshed and the two outer coarse and robust. The function of three canvases, which form a barrier at the bottom as the trammel net is usually stretched to the bottom, is twofold, because the small fish are caught in the middle because it fascinates, and the big hand, he ran in the above and also potendovisi fascinates because of their size, pushing the network to one of the sheets side by entering it in the big top, remaining trapped in the bag or sack which is to be leaning over the same shirt.

Libra: balance that takes different names according to region and The size, consists of a square network of large size, mounted on two curved poles that cross over and engage the four corners thereof. At the point of intersection of the poles is fixed a cable hoist a weapon, supported by a beam-mail inclinatio.
gillnets: calandole Such networks are used in a particular place and firmly hold vertically in this way because the fish is caught in its movement towards the network hits you, and then still fascinates subsequently detained.
Nasse: The pots are in the construction of rattan or other materials to form conical-cylindrical with an aperture (conical) falling in the same body and narrowing gradually. The marine organism that is flattened, or with bait inside, or because of various kinds in search of refuge (as a polyp) or a house that has entered the no longer able to exit. These tools are generally secured by suitable ballast on the seabed and are provided with the proper grippiale and float to the surface with its signal. The fisherman in this way can do his regular visits to the traps, remove the captured prey, calling various solicitations when necessary, and spin again before the trap by the buoy to carry out normal maintenance tool.
Net launch: Have tools consist of a network fabric, capturing fish moving from the surface to the bottom. Networks are rarely used by the professional point of view for their poor performance. Fishing is usually done close to canals or estuaries where the fish usually focuses on the capture. The network once thrown open, and fell at the bottom with small weights evenly distributed on the circumference. Pulling the top of the recovery network is closed and raised to form several pockets where the fish is trapped. The species caught p.azzurro, Sparidae, shrimp, sea bass and mugilidi stationed near the coast.
FISHING IN THE RIO Pramaera DURING
In the '50s fishing equipment were rare, and the fishermen had to invent them, but it is also true that once you fish more, for the simple fact that the seas, rivers and lakes were much more populous, the causes inexorable extinction of this long and has had many there who blames the normal evolution of the species, there are those who more consciously acknowledge the human selfishness of many environmental disasters that inevitably have an impact against it: in this regard about twenty 'years ago, Greenpeace (an environmentalist group "attacked" the world's best) launched the first campaign to clean the Sea North, who for decades has been subject to indiscriminate discharge of industrial waste in many flavors, as well as used as a dumping ground for all kinds of solid waste. But one could also mention the increasingly reckless Fishing made at the expense of all species great and small that are now disappearing in our waters for the sole purpose to grab everything at once without thinking of tomorrow has become increasingly uncertain, or of the many oil that cross all the seas of the world have accidentally poured on them miles and miles of oil with an inevitable memory surrounding habitat.
The most common fishing gear were "Charm " was cut branches and twigs of some trees, and were tied together by the reeds, after which they sit on the bottom of the river attached to the sides. The next day, very cautiously approached the bundle to the shore and suddenly thrown out of the river eels who sought refuge and protection among the branches are suddenly dry.
On other occasions, during periods of drought, when circumstances permitted, he deflected the river from your bed to another secondary creating an artificial barrier on the river bed, this gave the possibility of drying fish mullet and eels in a small pool of water. This method was called " SCANSAU " .
Another fishing system was called " BARREL SULA " which included a wooden pitchfork with a central 'sula' (or needle shoemaker), and when we went to look for eels under rocks with the skewering is this tool first wedging between the two points. This tool has since been replaced by common SPEAR ", which over time has been changed with more tips. Another fishing
very old in some places is still used today is "ON Purdon : Take 2 meters of thread sewing, folds in half and shove a needle Earthworms, andthe wire when it is full unite and become a circle earthworms of the coils to form a cluster, and this tied with a thread is left in a cane support on the river bottom, the eel worms are fond of throwing on them, after which you can pull out of the water capturing also 2 or 3 eels at a time, pull out the eels with their sharp teeth, even if they try to let go would still attached to the wire. Take out of the water, about 1 meter from the shore, where a hole is dug in previously (or place an umbrella on the contrary), the drop is inside.
Another method of fishing, among other things was forbidden to take a "dead sheep " died due to some disease (and inedible) exported the entrails with a small crack on his stomach, after which it was immersed in the river bed, the Eels, who were attracted by the nearby new food entering into the slot to eat, unable to find more 'output. The day after we carefully took out the sheep inside where it was always full of eels.
Another type of fishing, was always forbidden " S'ALLUA " which was to find the roots of a particular plant, which were crushed and thrown into the water, the substance that left these roots go was a very powerful poison Mullets poisoned both the Eels, not to mention all other species in this stretch of river, and had to be careful not to avoid problems also abound for those who ate the fish. Also in the '50s, one of the most widespread fish, partly because of the inability to buy the various fishing gear was the method FORBIDDEN said "A Bombay" which was to make a bomb prepared by expert hands that was launched in the middle of the school of fish, and only takes a few seconds to seeing the body of water become completely white caused by the sudden death of all fish gathered at that point. The fisherman then had the sole task of collecting all the fish in no time prior to arrival of some authority.
Other fishing methods can be " BALANCE ", "The REZZAGLIO ( NETWORK TO LAUNCH or SPARVIERO )," Trammel nets networks "and the common BERTAVELLI .

FISHING NETWORK LAUNCH
networks to launch, cast from shore or boat, catching fish cadendogli above is trapped in them. Their use is limited to waters with
shallow, and in Rio
Pramaera
This type of network is also named "Hawk."
FISHING AND BOAT RENTALS
addition to the commercial fishing licensee Rio Pramaera offered to the many tourists passing through the possibility of doing of sightseeing along the river, which have the 'opportunity to penetrate inside, in the most hidden, thanks to the many natural canals that the dealer was able to do in recent years. A very attractive location, surrounded by vegetation with reeds in several steps ago, almost to the tunnel, making light of the sun (especially at certain times of the day) very special. And if you are lucky you can enjoy the many aquatic animals that live there while they are in their nest with their young, or see them in the water is a glimpse of mullet or eel that roam the lagoon undisturbed. Then wishing for the most passionate, as well as hire a boat to make the tour, you can do the same to a dealer to permessino groped his luck with the fishing rod and some fish eel or mullet. The
Rio Pramaera and Maree
It has always been discussed as to why and the mouth of the river Pramaera (like many rivers in the world) was to open at a certain time of day or a particular stretch of the 'loop, but very few actually have focused on the real reasons that the dealer is forced by circumstances opened her own while at sea poured the many swimmers who enraged by 'sudden change of color and clarity of the water, unload their anger and their frustration with He believed that the only responsible. Not thinking that maybe if you opened it at that 'now was not to spite the tourist (with whom he has always had a working relationship and friendship) but simply because it forced him to open the sea at that moment: namely, when the sea (attracted by the moon) retires at the center of 'Ocean (thus creating the low tide), and then the river is at a level higher than its descent to the sea will become easier as a result. A phenomenon that happens every 6 hours, regardless of the will of 'man.
But let's explain what happens:
Today we know that the moon attracts the 'water of the oceans and that the Sun exerts its influence, but being more distant from the earth has less effect of' attraction of the moon. Sometimes the two forces have a combined action, at others instead they operate in conflict, in turn, causing the high and low tide.
so tide is nothing but the 'oscillation of sea level caused by the gravitational pull of the sun and moon combined. The deformation of the periodic and regular ground water is manifested by the recurrence in 'period of 24 h 50 m (lunar day average) of two elevations (high tide or stream) and two drops (or ebb tide) sea level. The two flows and ebbs two alternate approximately every 6 hours, generating two currents of opposite direction (tidal currents).
