I would think in your area of the world, it is especially hard to convince people that hunting is conservation. You're surrounded by Hindus, and your nation is a high-population muslim country. By those circumstances, policy has been to touch nothing, harvest nothing, out of necessity. Each of us needs to meet our neighbors at their level of understanding and build trust while we expand minds.
It's a little bit more complex than that. You see... bird hunting and (to a lesser extent) deer hunting, rabbit hunting & boar hunting are pretty common pastimes in the rural parts of our country. Venison and wild game meat is considered a delicacy at the family meal tables of most rural Bengalis. Being a country of 700 rivers, waterfowl hunting is an almost universally popular hobby in rural areas. As a matter of fact, from October to April... you'll be hard-pressed to find a rural home where pin tails or whistling teals or bar headed geese or greylag geese AREN'T eaten.
Nine out of ten Bengalis view hunting (and fishing) to be a positive thing.
BUT
This only extends to game animals which are typically seen as conventional tablefare (upland birds, waterfowl, deer, rabbits, buffalo, nilgai, boars & the like).
The problem begins when you try to convince them that "Trophy Hunting" is actually a good thing. For instance, when I was Chief Conservator Of Forests of Bangladesh (and later a Member of Parliament for two consecutive terms)... I brought up the proposal that we should re-legalize the hunting of Royal Bengal tigers in order to reduce human-wildlife conflict in the rural areas outlying the Sundarbans mangrove forests (where an average of 52 human beings are killed by Royal Bengal tigers per year)... my colleagues at the Ministry of Forests (even my staunchest supporters) flatly told me that I would be committing career suicide by even bringing this proposal up. It didn't matter that the population of Royal Bengal tigers inhabiting the Sundarbans is currently at an all-time high (far exceeding the terrain's L.C.C or Land Carrying Capacity). I was simply told that legalizing Royal Bengal tiger hunting was a complete no-go. From a hunter/conservationist's perspective, this is very tragic. But from a politician's perspective... I can totally understand why my colleagues stopped me. They arguably saved my career and allowed me to retire peacefully.
In other words, let me put it simply for you: Nine out of ten Bengalis would view hunting a Cape buffalo in Africa as a good thing (because it's a game animal typically associated with tablefare). Two out of those ten would view hunting a lion in Africa as a good thing (regardless of how much lion hunting can have an overall positive effect for wildlife conservation). I was however, recently able to get a very talented group of young university students (while conducting a lecture on sustainable wildlife management at Rangpur University) to view the trophy hunting of African lions in a much more positive light... after I showed them slides of the meat harvested from a hunted African lion being distributed amongst local rural African communities. I explained that in Africa... absolutely nothing goes to waste. Perhaps, we would have better success in inciting relatability amongst the common Bengali masses if we changed name "Trophy Hunting" to "Management Hunting" (or something along those lines).
In regards to being surrounded by Hindus, this is also not as clear cut an issue as people think. The Hindus living in Bangladesh for generations are more or less okay with hunting (quite a few even hunt regularly themselves). Most of them will eat meat (except for beef). The problem is the Hindus living in India (which surrounds Bangladesh on three sides). They view Bangladesh as a neocolonialistic possession of theirs and have been frequently trying to get all forms of hunting (as well as firearms ownership) banned in Bangladesh.
Our previous government (who was overthrown on 5th August of this year) were bootlickers to the Indians because the Indian government basically installed them here so that they can run Bangladesh like an Indian colony. Our previous government were thus quite restrictive regarding hunting & firearms (although they couldn't afford to outright ban hunting & firearms ownership because it would incite a very vocal discontent amongst rural Bengalis). After our new government (who basically hate the current Indian BJP government for ruining our country in the last 16 years) came to power, they relaxed hunting & firearms ownership laws to more reasonable degrees. Because it's an army backed government. And in Bangladesh, nine out of ten army officers view hunting & firearms ownership as a good thing.
We are still a long way from making the common Bengali unde that hunting ten Royal Bengal tigers a year (in order to save a thousand) is a good thing. But never say never.
I covered many of these points in Chapter VIII & Chapter X of my autobiography. Not trying to sell books or do product promotion, but it would help you understand this topic in a little more fleshed out manner.
