Limited entry and effort rationalization |
![](bt.gif) |
Gear, area and temporal restrictions, closed seasons |
![](bt.gif) |
Mesh size regulation to avoid netting juveniles |
![](bt.gif) |
Expansion of fishing to further deeper areas |
![](bt.gif) |
Installation of FADs for augmenting yields |
![](bt.gif) |
Reduction of coastal environmental damage
|

Enhancement of awareness among stake holders |
Awareness programme on the exploitation of juveniles of pelagic fin fishes |
(Dangers of exploitation of juveniles was highlighted in this
programme) |
![](btr.gif) |
The exploitation of juveniles, sub-adults and adults of oil sardine were to the tune 19.6% (57,036 t), 38.6% (112,326 t) and 41.8% (121,636 t) respectively by all gears during 1999-2000.
|
![](btr.gif) |
Out of this the ringseine gear alone accounted for 53,614 t of juveniles and 50,250 t of sub-adults of oil sardine. |

Economic loss works out to crores of rupees. |
![](btr.gif) |
Recommended increase in mesh size and avoiding fishing juvenile. |
![](btr.gif) |
A handout (vernacular) on dangers of large scale destruction of juveniles was distributed among the various stakeholders. |
Migratory species - An analysis |
![](btr.gif) |
Proposed a Production function model based on the catch-effort data of the Skipjack tuna in Lakshadweep |
![](btr.gif) |
Tuna landings in relation to the meteorological factors in the insular ecosystem showed evidence that wind speed and surface circulation limit the spatial distribution of tunas
|
![](btr.gif) |
Success of pole and line depends on expertise of fishermen, availability of livebaits, biting behaviour |
![](btr.gif) |
Validation of Potential Fishing Zones (PFZ) using remote sensing data attempted for tuna fishery of the islands. |
![](btr.gif) |
A funded project to augment tuna production by establishment of FAD’s and study the feeding and schooling behaviour of tuna schools in its vicinity is being implemented |
