I could go on bru ,
it really gets to me , but there is a slight flip side ~ Pelagics are targeted (jacks & tuna with multiple boats & ring nets ) but the continental shelf is quite close in at Senagal ~ 2 ~ 3 km in places and they cannot get at the sailys , beaks etc ~ some good pulls there . Also , any heavy reef area is more difficult to get at with nets ~ hence the garrick etc . ~ You also get big threadfin and cobb in these locations . ~ A case of picking your venue carefully , and hitting it at dawn or dusk before the netters get going .
Jigging is probably out the question unless you off shore and hit the tuna , jacks etc that way ~ much easier to cast metals to bird marked shoals .
Just a thought ~ Guinea Bissau Bijagos ~ outer islands only , there is a French crew running jigging/popper trips ( also a brit guy ) and it is truely aweome fishing ~ if you want the details ~ www.worldsportfishing.com ~ the guy is Richard Sheard ~ good guy ~ but take your own gear ~ the tackle pack offer isn't up to it .
Can put you in touch with guys that have done it ~ all rave & rave about it .
