searched with a hand net, or, in deeper water, by 

 fishing close to them with fine tackle. 



Rocky ground, ground too rough for trawling, and 

 ground encumbered with wreckage, when below tide- 

 marks, can only really be fished by hook and line. 

 Native fishermen have usually learnt by long experi- 

 ence the best localities for line-fishing, and, in the 

 absence of such guidance as they can afford, experi- 

 ment alone can discover it. In the absence of local 

 guidance as to baits, almost any large marine worm, 

 mussels, or similar soft-fleshed shellfish, the tails of 

 hermit crabs, cuttle-fish cut into strips, or pieces of 

 almost any fish preferably such as contain a quantity 

 of fat or oil may be tried as baits. 



Trammels and gill nets (see pp. 335, 337) are most 

 efficiently used when set from the end of a reef of rocks 

 where there is a rapid drop into deeper water. 



The surface waters of the sea, whether in-shore or in 

 mid-ocean, should be fished by tow nets of compara- 

 tively large mesh at various depths (see p. 188), or by 

 a " young fish net " (see p. 341), and to such localities 

 the general remarks under the head of " Tow Netting " 

 are applicable. We know of no net really well adapted 

 for taking the larger fishes of the surface waters or 

 middle depths of the ocean. 



At the actual surface a line with a spinning or 

 trolling bait can, of course, be used, and fishes are 

 often found accompanying floating weed, wreckage, 

 or large pelagic jelly-fishes. 



Sometimes in calm weather a powerful light displayed 

 over the ship's side attracts surface fishes, or, at least, 

 makes them visible, and renders their capture with a 

 dip or hand net possible. 



In very deep water, down to about 3,cco falhcir.s 

 fishing may be conducted on the bottom either by
