I have freelanced for several national television news outlets. While I consider them entertainment to a large degree, their standards are usually 2-3 sources and they do their journalistic best.
Local newscasts not so much. They are only a vehicle for add sales (national channels make more from carrier coverage). The local newscasts usually are about shocking viewers and have little real news. There may be exceptions but I see little journalistic integrity after 25 years in the business. They are probably trying to appeal more to local fishermen (fisher-people?) than hobbyists also.
To any of their credit, this subject is probably difficult for them too as they do not really get it or its impact.
