"I personally believe there is a level of exploitation going on here, with churches selling things like anointing water and car stickers," said Apostle Samuel Yaw Antwi, General Secretary of the Ghana Charismatic and Pentecostal Council.
All parameters point to an organism which is vulnerable to low levels of exploitation, as has been demonstrated through changes in catch per unit effort in Philippines Nautilus fishery studies [3].
"An attack of this type involves many different phases of reconnaissance and multiple levels of exploitation".
There is one industry in which harm-reduction strategies based on decriminalisation have proven disappointing where the adoption of public-health-based approaches involving legalisation, regulation, inspection, inclusion in the tax base and so forth has arguably led to higher levels of exploitation and the empowerment of abusive, violent international criminal networks.
But to succeed, such strategies are likely to require more than just attempts by management to control annual levels of exploitation.
All three thresher shark species were assessed as Vulnerable by the IUCN in 2007, as their low fecundity cannot sustain high levels of exploitation.
Its low reproductive rate may render it susceptible to overfishing, and given existing levels of exploitation, the International Union for Conservation of Nature (IUCN) has assessed it as Near Threatened.
Despite this, the International Union for Conservation of Nature has assessed this species as being of Least Concern, because its wide distribution and relatively high productivity seemingly allow present levels of exploitation to be sustained.
In other instances, police have exhibited shameless levels of exploitation: In one reported example, a police officer in Cape Town demanded a sex worker give him money in lieu of arrest; when the sex worker told him she possessed only a meager100 South African rand, or the equivalent of $1.25, the police officer even pocketed that pittance.
The assessment concluded that "an overall population size reduction of at least 30% may occur within the next 10 years or three generations due to actual or potential levels of exploitation and the effects of introduced taxa, pollutants, competitors or parasites".
They cite that "the species is believed to have undergone a decline of 80% over a period of 27 years, due primarily to a decline in area and quality of habitat within the known range of the species and due to levels of exploitation".
