Step 1: Understanding the Concept:
Trawl net design and terminology: the central forward horizontal section of the headrope or footrope between the two side wings is designated as the bosom.
Step 2: Detailed Explanation:
In fishing gear design and trawl net anatomy:
- A bottom or pelagic trawl net consists of several structural components:
1. The Bosom (B): The central, middle horizontal portion of the trawl net mouth situated directly between the two forward wings (forming the center of the headrope [upper bosom] and footrope [lower bosom/belly bosom]).
2. The Wings: The forward lateral extensions on either side of the net that guide fish toward the mouth.
3. The Overhang (Square): The section of upper netting extending forward over the lower bosom to prevent upward fish escape.
4. Cod-end: The tapered trailing bag where catch concentrates.
Step 3: Final Answer:
Therefore, the portion of the net mouth between the two wings is The bosom, corresponding to option (B).
