i think the pet fish hobby is a lot less exploitative than other “pet” niches. it still happens, of course, but it’s transitional. since breeding is a core element to the hobby as fish don’t live too long and spending a lot of money on a fish that won’t breed and die within a few years is not a good incentive (koi is an exception here, they live for 200+ years if well taken care of, and part of the price is how old the koi is (the older the more expensive) and how beautiful the colors it has, it is also a factor to be an authentic japanese bred specimen). for other, less complicated species, mills do exist, and sell bulk to the pet stores, and since they’re from mills, they’re genetically hampered, which makes the fish “low quality” as in, die much faster and is too sensitive to parameters - so they’re usually not interesting to hobbyists and collectors. this is not saying stores aren’t important, it’s the gateway for the hobby to gain more enthusiasts, and as people get involved in the hobby through exposure from a store, they soon go into the hobby trade of good and healthy specimen. which neatly splits the “fish mill” category of unethical people who need something that is easy and fast to breed to make cash, vs the hobbyists who needs something that is sturdy, genetically variable, and more healthy; focused on species that are not too difficult to breed to sustain a population at home, and maintain genetic variance by collecting new specimens from hobbyists to add to their genetic pool, which further protects wild populations. wild caught fish is usually riddled with parasites as well, which is another risk a lot of hobbyists prefer to avoid. there is just very little incentive to work with wild caught fish unless it’s a newly discovered species, in which case the goal is usually to quickly establish an aquarium strain to avoid all the complications and dangers of a wild caught species (and for mills, to figure out how to quickly mass produce them in their vats to make quick money on the ‘newness’ of the species on the market). it should also be pointed out that saltwater is far less popular because of the inherent difficulties of breeding and maintaining a saltwater tank; even if saltwater fish is usually stunningly beautiful in their wild form.
i think, for any fish hobbyists, there are generally parameters that are important.
how does the fish look? body shape, colors, fins. it is very rare for a wild population to be as colorful as aquarium strains, have perfectly formed body shapes, and fins, and thus fortunately people don’t want wild specimen (not to mention the risk of parasites).
how healthy is the fish? health is important, people don’t want the fish to be riddled with genetic diseases. this makes mills undesired for hobbyists.
how easy is the fish to breed? if the fish can’t be bred, there is nothing for the hobbyist to do. no traits to refine. no finnage to elongate. no complicated and fascinating breeding process to establish new populations. fish who fits in aquariums normally do not live for more than 1-5 years, and then all that money invested into acquisition and maintenance was ‘wasted’.
how easy is the fish to keep/maintain? some species require a lot of specialized parameters, which may make it difficult to impossible to keep in your collection. if keeping the fish requires too much work, only hardcore specialists will focus on keeping and breeding them (i.e. Discus); and they usually don’t have time, resources, or space, to keep anything else, making them specialized on that particular species. this also means that species like Discus is rarely sold in pet stores unless the pet store has ‘personal interest’ in the species. since they’re hard to sell due to the difficulty level, and they are usually riddled with diseases and infections and need a lot of care and medication and costs of maintenance. so without access to hobbyist communities, you’ll have difficulty finding them to buy. i don’t know of any Discus mills either due to the difficulty level of breeding and cost of keeping them. this is a prime example where facebook banning groups is directly threatening the Discus continued existence of aquarium strains. to add, color and health is not always the most important factor, i.e. saltwater is notoriously difficult to maintain, and most hobbyists just don’t bother with it, unless deeply specialized, despite saltwater fish being the most colorful, even for wild caught specimen.
how easy is the fish to collect? fish that is difficult to collect (no other hobbyists have them) usually also means difficult to find different genetic pools of. if you can’t introduce new specimens of the same strain, then your population will slowly deteriorate and eventually be riddled with genetic diseases. space helps here, many people will cross breed with multiple generations of their own population to try and spread out the genes, but even so, there is still risks of their gene pool getting bad. wild specimens are undesired because their genes usually dominate your carefully bred traits, and your strain is lost. plus, parasites.
how much do i trust the source? every time you get new fish, there is risk of introducing infections and diseases. not just genetic diseases. i.e. when you want to add new genetic materia to your guppy population, if you source it from an unknown farm/mill or unknown seller. you are taking a huge risk of losing your entire population by introducing a disease the new fish may be resistant to. it’s a pretty common problem for pet stores to have their guppy/platy/swordtail populations get decimated with each new shipment.
was it bred ethically? this is a bit of a repeat, with greater understanding of the needs of your favorite fish species, seeing the small spaces they’re housed in the pet store, the poor quality food they’re fed, and knowing how they’ve been bred by a mill, hobbyists don’t want to deal with the abuse. it impacts the fish health and stress, and the fish will usually only live a short life.
was it wild caught? wild caught means parasites and potential infections and diseases. not to mention usually don’t have the colors/fins of aquarium bred fish. this is a notorious issue. experienced hobbyists are well aware of the problem, and rarely have a reason to collect wild caught specimen. especially if it won’t breed in an aquarium environment. fish don’t live long enough to invest money, time and effort into a species that won’t breed.
TLDR; the hobby do have a lot of problems. but ethical/sustainable source is not one of them since serious hobbyists avoid pet stores and mills. facebook banning aquarium fish groups is damaging to the continued existence of species within the hobby and having the opposite effect by increasing the sourcing of specimen to pet stores, and thus, the profit to mills and wild caught specimen.
thanks for the detailed reply
