연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

By attaching a radio or acoustic sound transmitters, or combinations thereof, to the float line of nets recovery of gill nets will become much easier, and timely. This could save millions of fish and other marine life, as well as the economic value of lost nets, which can cost thousands of dollars a piece.

The invention claimed is: 1. A recovery device in combination with and for locating and recovering a gill net lost at sea, comprising in combination: a gill net having a netting mesh, an upper float line, and a lower weighted lead line along upper and lower edges, respectively, of said mesh; floats attached to said upper float line, and weights attached to said lower weighted lead line whereby said gill net floats below a surface of said sea; floating buoys attached to said gill net to mark location of said gill net under said sea surface; means for tracking the location of said gill net in the event that said gill net breaks away from said buoys and floats away undetected below the surface of said sea comprising a radio transmitter within an enclosed container body attached to said upper float line; a timer within said container body to initiate radio transmission by said radio transmitter after a normal retrieval time for said gill net has elapsed indicating that said gill net is floating undetected under said sea and allowing tracking of said gill net. 2. A gill net recovery device in combination with and for locating and recovering a gill net lost at sea, comprising in combination: said gill net having a net with openings for catching fish gills therein, said net having a netting mesh, an upper float line with floats attached to the net and a lower weighted lead line with weights, with the netting mesh in between said upper float line and said lower weighted lead line, the gill net further having lines connected to one more floating buoys and lines connected to one or more display flags for floating above the upper float line, wherein the floats, the one or more floating buoys and/or one or more display flags can break away from the upper float line, lines connected to one or more floating buoys or lines connected to one or more display flags, causing said gill net to float away undetected below a surface of the sea, at least two radio signal transmitters for transmitting radio signals to a remote receiver and located inside respective buoyant container bodies; wherein said buoyant container bodies are releasably attached to said upper float line and adapted to float to the surface of the sea and allow said at least two radio signal transmitters to transmit said radio signals; wherein said buoyant container bodies comprise releasable attachment means and interval timers, said releasable attachment means comprising at least one fastener, each of said buoyant container bodies attached by said at least one fastener to said upper float line above the netting mesh of the gill net, said interval timers activate the releasable attachment means to release said buoyant container bodies and radio transmitters therein from the upper float line at an end of a fixed time period controlled by the interval timers and permitting each said radio transmitter of each said buoyant body to send out a locator signal incorporating a numerical sequence in which each said buoyant body was released freely from said gill net; and wherein each said radio transmitter automatically begins transmitting said locator signal which defines a trail over time of the lost gill net to support tracking and identifying an exact path, velocity and location of said gill net from which the floating bodies and respective radio transmitters were releasably detached. 3. The gill net recovery device in combination with and for locating and recovering a gill net lost at sea as in claim 2 wherein each said buoyant container body comprises a substantially tubular body. 4. The gill net recovery device in combination with and for locating and recovering a gill net lost at sea as in claim 2 wherein each said radio transmitter communicates with at least one satellite tracking system, at least one radio telemetry locator, at least one radio remote locator or any combination thereof. 5. The gill net recovery device in combination with and for locating and recovering a gill net lost at sea as in claim 2 wherein said gill net comprises a unique identifiable ID identifier attached to each net. 6. The gill net recovery device in combination with and for locating and recovering a gill net lost at sea as in claim 2 wherein each said radio transmitter inside each respective buoyant container body has two contacts adapted to complete an electrical circuit when contacted by sea water and trigger the respective interval timer when said gill net contacts sea water, said contacts triggering the respective interval timer starting each said radio transmitter inside each respective buoyant container body after a predetermined interval longer than the fixed time period, each said interval timer starting each said radio transmitter which sends steady or intermittent signals until a DC power source of each said radio transmitter is exhausted, said at least two radio transmitters transmitting coded signals identifying said lost moving gill net. 7. The gill net recovery device in combination with and for locating and recovering a gill net lost at sea as in claim 2 wherein said remote receiver locates each said respective radio transmitter by triangulation to locate the lost gill net. 8. The gill net recovery device in combination with and for locating and recovering a gill net lost at sea as in claim 2 wherein said at least one fastener comprising opposing clamping jaws, each said buoyant container body is attached to the float line via said opposing clamping jaws openable by an actuator after said respective interval timer times out, each said buoyant container body also connected to the float line by a respective connecting line on an internal reel attached to said buoyant container body, each said container body floatable to the sea surface while attached to said float line via said respective connecting line to the gill net. 9. The gill net recovery device in combination with and for locating and recovering a gill net lost at sea as in claim 2 further comprising a global positioning system receiver within each said buoyant container body incorporating location information into a distress signal message whereby the present location of each said radio transmitter of each said buoyant container body can be incorporated into the locator signal being emitted. 10. The gill net recovery device in combination with and for locating and recovering a gill net lost at sea as in claim 2 wherein each of said at least two radio signal transmitters is released to said sea surface at a different time, while being tethered to said moving gill net by a tether. 11. The gill net recovery device in combination with and for locating and recovering a gill net lost at sea as in claim 10 wherein said at least two radio signal transmitters are detachable from said gill net at predetermined intervals as said gill net moves within the sea water, each said radio signal transmitter floating to the sea surface and starting transmitting after said respective predetermined intervals, the transmitted radio signals leaving a perceptible trail observable by a number of cumulative signals pointing to the movement of the gill net. 12. A method for locating and recovering a gill net lost at sea, comprising the steps of: suspending a free floating gill net in a sea and below a surface of said sea, said gill net having a netting mesh, an upper float line, and a lower weighted lead line along upper and lower edges, respectively, of said mesh; attaching floats to the upper float line, and weights to said lower weighted lead line allowing said gill net to float freely beneath said surface of said sea; attaching floating buoys to said gill net to mark location of said gill net under said sea; and attaching to said gill net a radio transmitter within an enclosed container body, said container body including a timer initiating radio transmission by said radio transmitter after a normal retrieval time for said gill net has elapsed indicating that said gill net is floating undetected under said sea thereby allowing tracking of said gill net.
