Fishing Technology

• Traditional Beach Seines in India:
• Rampani Net: A famous, massive traditional beach seine operated along the southwest coast of India (specifically Goa, Karnataka, and the Konkan coast of Maharashtra) to capture coastal schooling pelagics (Indian oil sardines and Indian mackerels).
• It consists of hundreds of netting sections laced together, measuring up to $1-2\text{ km}$ in length, operated by 60–80 fishermen and large non-mechanized Rampani rowboats.
• Stake nets and Dol nets are fixed tidal bag nets; Trammel nets are bottom-set three-walled entangling nets.
• Correct Option: Option 3 (Rampani).

Matching the items of List I with List II for Different types of craft and gear, their operation and their maintenance:

The correct combination is Option 4: (A)- (IID, (B) - (IV), (C) - (), (B) -.

Correct option: (4) (A)- (IID, (B) - (IV), (C) - (), (B) -

• FAO ISSCFG Gear Classification System:
• The International Standard Statistical Classification of Fishing Gear (ISSCFG) was adopted by the FAO/CWP to standardize global fisheries statistics.
• It classifies fishing gears into categories based primarily on the principle of capture (e.g., surrounding nets, trawl nets, gillnets, traps, hooks and lines, falling gears).
• Correct Option: Option 2 (Principle of capture).

• Suberkrub Otter Boards:
• Designed by German engineer Karl-Heinz Süberkrüb, Süberkrüb otter boards are high-aspect-ratio, vertically cambered hydrofoil doors.
• Because of their high lift-to-drag ratio ($C_L / C_D$) and stable midwater shearing properties, they are standardly used in semi-pelagic and pelagic (midwater) trawling.
• Correct Option: Option 3 (Semi-pelagic trawling).
