I would encourage you to guide him to seek a MS, which would open his options beyond working as an entry-level technician position for most State or Federal agencies that are hiring.
I graduated with a BS in Fisheries and Wildlife Biology with a wildlife and wetlands ecology emphasis, I was hired by Michigan State University as a research tech. as a diver, changing film packs and batteries in an array of stationary current meters around a coal fired generating facility located near Lake Michigan at a drowned river mouth site. After that, I ended-up taking more fisheries courses and applying to graduate school in fisheries science and limnology with an emphasis on the Great Lakes. I did my masters research as part of an EIS (Following NEPA passage, Universities got involved in the environmental consulting business in a big way.) on a pumped storage hydroelectric plant. The fish mortality estimates we (MSU) formulated via modeling techniques eventually lead to a "sweetheart" settlement between the utilities owners and the State/MDNR, largely because of the State's employee retirement fund's heavy investment in their(utility companies) preferred stock. Several folks worked hard behind the scenes for years to overturn this agreement, eventually resulting in the Michigan United Conservation Club's parent organization (National Wildlife Federation) stepping-in and filing suit against the utilities (Consumers Power and Detroit Edison) and the MDNR for pollution of the Great Lakes via the massive fish kills caused by annual plant operation.
The eventual outcome was a "change of sides by the State" as well as an eventual settlement reached that involved placement of a barrier net around the plant, as well as retro-active punitive damage payments, and annual payments into what eventually became the Great Lakes Fishery Research Trust. This whole process moved at a near-glacial pace. I eventually ended-up running a field research lab. for MSU, running another EIS on the St.Mary's River, assessing the potential environmental impacts of winter shipping on the connecting waters of the St. Lawrence Seaway and the Great Lakes. Over those years I had a broad variety of opportunities to get hands-on experience in modeling, study design and field sampling implementation for a variety of sampling gear from various gillnets, otter trawl, frame trawl, trapnets, larval fish pumps, larval fish sampling tow nets and sleds, invertebrate sampling gear, as well as emergent and submergent macrophyte mapping and biomass estimation techniques and zooplankton sampling and ID work;far more and to a greater in-depth degree than what I would have been exposed to or involved-in had I gone to work for a State or Federal fish and wildlife agency. I even taught the Ichthyology labs. for three years, even though I had a research assistantship. I even learned how to weld, make a gillnet and trapnet from scratch, repair an outboard, and troubleshoot complex electronics, etc.
The downside is that I eventually ended-up filing conflict of interest charges against my supervisor and former major professor. Coincidentally, two of his graduate students filed charges of theft of intellectual property(quite common among university profs. in this era). He and one of two other profs. were eventually found guilty. I found out that, as an off-campus Associate Professional I was not represented by the MSU Employee Union. I was informed by my department chairman that my position was "soft money grant funded" and I was going to be let go. He did write me a letter of recommenation... I ended-up working for the USFWS Sea Lamprey Research Laboratory, working on proof of concept efforts for mass release of spawning phase male sea lamprey(sterilized via interperitoneal injection of a germ cell specific mutagen) into the St. Mary's River as a means of population regulation and control. After running a laboratory, writing quarterly reports, constructing and managing a budget, etc., working as a glorified pair of hands was not very challenging. Plus, over my time at Hammond Bay, I determined that lake trout restoration efforts in the lower Great Lakes were quite ill-conceived...a key USFWS initiative in this geography,so I left, taking a job with a pharmaceutical company.
Had I not had four semesters of statistics and a pair of population dynamics and modelling courses via my graduate education, I would not have been hired.
