Hey all, this week is going to be the start of a long awaited project for me. For context, I have a backyard pond that's about 5000 gallons in Southern California. This is going to be pretty ambitious as the title of the thread suggests, but I think I have a very real shot at doing this considering my climate and setup. This week, I am getting my fingerling Florida bass that are the best of the best in terms of genetic potential to grow giant. They are some special fish that's for sure. These fish will start at 1-3".

Currently the pond houses a forest of anacharis, water lilies, driftwood, boulders, rock, gravel, pickerel bog plants, a wetland filtration system, a large mechanical/biological filter, UV clarifier, waterfalls and a huge aerator. The pond maintains temperature through the winter above 50 degrees, and ranges between 75-84 degrees in the summer, consistently around 78-80. I have an extended growing season for my fish because of these mild temps, often with warm autumn and winter temps extending the growing season past 9 months annually.

The pond has plenty of aquatic insects that lay eggs and other invertebrates. I have stocked it with scuds as well and will be putting more in this week as a cleanup crew and live forage for young fish. To start my bass off, they will have several thousand fathead minnows and golden shiners as their starter forage. These baitfish I am gutloading daily with omega one freshwater flakes to ideally ensure they are stronger against parasites and disease, while also balancing their profile out to combat thiaminase. These baitfish are unable to be quarantined due to the "buy in bulk" nature, but I am hoping that good feeding and colder water temps currently with high oxygen will help combat any diseases they may have. Haven't seen ich and they all appear to be relatively healthy and are readily feeding. They are not bought from the lfs, but hatcheries, so I am hoping they are better taken care of, seemingly they are so far. These baitfish will likely be the main diet for these juvenile bass until they are wiped out in a couple months. Once the bass hit 4-5" I will be introducing a large amount of juvenile bluegill to become the backbone of the live food for these bass. The hope is for the bluegill and other species to reproduce and create a natural system of forage and predators supplemented by pellet feeding and foods like tilapia fillets, shrimp, maybe market purchased items like squid, and freshly caught striped bass from the lake cut into cut bait. I also will add crawfish to the pond once the bass get large enough to regularly consume them (12").

I will have 5 bass that I start with which I will cull down to ideally 2 females that make a run for the world record. The goal is not just weight, but also length. I want my fish to not be morbidly obese to take the record, but rather something with an enormous frame. I have seen reports of bass from Florida over the 30 inch mark, and stories of people seeing fish that are above 35 inches long. That is the fish I want. I want to push the Florida bass to the extreme limit for the species and find out just how big they truly can get.

In order to do this, I have to race to get my fish to the 18 inch mark as fast as possible to set up the runway for the fish to achieve 36 inches over the course of its life. The goal will be to do this in 1 calendar year which is pretty much faster than what anyone has done with bass previously. After 18 inches things slow down considerably, so getting there sooner and having high growth potential from the genes at a young age to keep pushing is my idea. Private pond owners can get fish to 18-20 inches in 18 months with large acreage ponds, but I need exceptional if I want to grow a record, and I think I can do it because I have a hyper-controlled environment with hand feeding in play. Bass grow fastest in their first few years of life as with any fish, so maximizing that time with healthy food and consistent growth is how I think I can shatter the world record and have a fish no one has even dreamed of.

Any tips or concerns that others might have would be well-appreciated. This is my thought process on things, and would love input from others. Concerns I have for the start is dealing with thiaminase from fatheads and golden shiners, but hopeful that gut loading will help, and knowing it's not a long term diet either. Also considering the bass are pellet-trained and should take high quality pellets that I have (Northfin JumboFish and Northfin Carnivore), I hope that is not an issue. Other issue might be disease from feeders, and that one I don't know how to address because I find it hard to treat a 5-7000 gallon system with the inability to do regular water changes.

I'll post pictures of the fish and pond this Friday when the fish come in.

I know I am a week late on this but here are the florida bass in my pond. There's about 7-10 of them in there right now all in the 1-2.5 inch range. They are eating somewhat but not super well. I am feeding them live daphnia, pellets, I have tried brine shrimp and blood worms and they won't eat them. They all are spending most of the time looking at the rosie reds and fatheads. I also have the big golden shiners in there. I have thousands of minnows, I have only seen one bass eat a minnow, but have seen all of them chase the minnows unsuccessfully. Some of the larger ones may be eating minnows and I can't tell. They all are big enough to eat the smallest minnows in the pond, but they don't appear to be the boldest hunters yet. They have been in the pond for a week and they are challenging to feed to say the least, but I am hopeful that they will keep eating things and soon get to the size where the minnows are an easy regular meal. Once that happens, their growth will be astronomical. All the minnows are gorged and filled with omega one fish flakes, pellets, and brine shrimp/daphnia/bloodworms. They eat anything and everything I put in the pond. They are doing well. The minnows should all spawn in the pond once the water warms into the mid to high 60s this spring. Right now afternoon temps are in the low 60s, mornings in the high 50s. The bass are just tricky sometimes but hopefully they hit their stride soon. Any tips on this are appreciated.

Ambitious setup and plan, but the biggest risk is still disease and nutrient overload from unquarantined forage. You might consider transitioning early to pellet-trained feeding and limiting live feeders, plus having a plan for large-scale treatments like salt or UV redundancy if something breaks out.
 
The pictures of the pond look great. Let me know if there is a build thread here on the forums.

Wow. Very nice. Love the plants and rocks.
I fed my small bambusa with live rosies. Same idea as you...to get them big and strong while small. Then I transitioned to frozen market fish.
I wouldn't use salt in the pond. It will kill the plants and ruin water quality real fast.
Keep us posted on progress. Very exciting project.

Agreed on risks, but unfortunately salt is a problem because it would kill the plants. UV redundancy I am not sure how that would really do much more for me considering I already have a UV clarifier on the pond. Best options I can think of down the road is treating food with meds to ensure that the bass are clean from parasites or disease. Other option would be to do a full pond treatment with MinnFinn or something. Right now I don't seem to have any disease issues that I can clearly see, so I am hoping that things stay alright. My plants have grown tremendously with the warmer weather this last month since these last pictures which has added abundant filtration despite the large numbers of fish and probably some spawning going on for the fatheads and shiners, adding to the pile. With all the aeration I have we should be fine.

Thank you! My family loves the pond, it is kind of the setpiece of the backyard. I don't have a build thread on here but it started with me just digging a hole until I realized I was in over my head and worked with a company to finish the project with proper tools and experience. It turned out amazingly and this is only the second year of the pond (completed June '24) and the ecosystem is now maturing which has been fun to watch

Yeah the rosy reds/fatheads are perfect for me in getting the bass to the right size. I will be stocking this pond with some coppernose bluegill once the bass get large enough to not have to compete with them for food like pellets or small fish and get bullied out of meals, and bluegill grow fast, reproduce a ton, and have no thiaminase. That combined with feeding pellets, shrimp, tilapia, etc. should make for a balanced diet that is clean growth fuel! I agree on the salt, would not end well for my plants.

The most recent update I can give is that since these pictures were taken a month ago, the largest bass look to have already grown an inch or more, and that was with water temperatures regularly in the 60s and sometimes in the 50s. We have had a string of water temps in the mid 70s now for about two weeks which is borderline best growth temps for bass and am hoping that they keep packing on the size. Larger pellets ideally entering their diet soon if they will take them, and as we get into these warm months with water temps constantly in the 70s-low 80s, their growth will explode. I'm expecting >2 inches a month from these guys with the food and water quality provided. The goal is to hit 18-20 inches by the end of their first calendar year in the pond to set up the runway for them hitting massive lengths and weights later, hopefully over 30 inches and over 22 lbs by the end of their lives. Should be doable with these genes and the food.
 
Size update on the bass: I don't have pictures, but the largest bass in the pond have grown over 2 inches in the last month and half in the pond. Saw 2 individuals tonight with one clearly about 4 inches long (very close in size to the largest shiners I have in the pond) and thick through the body. Mind you that this growth was achieved with water temperatures well below optimal growth ranges for most of that time. There are smaller bass in the pond as well who have not been getting as much food due to lack of prey availability in the proper size range, but minnow spawning that is almost guaranteed to be occurring should help them catch up quickly. There appears to be about 3-4 bass that are pulling ahead in size out of the 7-10 in the pond, which is exactly the plan. Ideally they will sort themselves out through cannibalism as sizes increase in the larger bass, but if not I will manually harvest once they get to the right size and cull to the top 2 growers who are females. Hopefully in about two weeks or so I will be able to get some GoPro footage underwater and get some pictures for size updates. The plants have also exploded in growth and I will need to harvest some anacharis from the pond soon as it is taking over the pond. However, it should act as a good nursery right now for fry from the minnows and shiners!
