8/1/2023 0 Comments Sheepshead fish mn![]() Minnesota Department of Natural Resources. Habitat: Primarily in large rivers and shallow lakes that have mud or sand bottoms It is one of the most often caught fish in our fishing programs. Present in Park: Commonly found in the Mississippi River. This makes them hard to detect, which is how they got so good at stealing bait. Despite munching on crustaceans all day, they’ll bite your bait very lightly. Coloration is gray with purple/bronze reflection and rounded triangular tail. Sheepshead earned the nickname Convict Fish due to their stripes, but this name is also fitting for another reason. It has a humped back with a long, sloping forehead and white lips. Key ID Features: Freshwater drum average 10-14 inches in length. There is some indication that this fish, with its big molar-like crushing teeth, may be learning to eat zebra mussels.Freshwater drum is the only member of its family in North America to occur completely in freshwater habitats.Freshwater drum's eggs float on the water surface until they hatch, sometimes traveling for miles on rivers or windswept lakes before the tiny fry (newly hatched fish) emerge.The otolith help fish stay balanced and oriented in murky water. All vertebrates have ototliths in the inner ear but the freshwater drum’s can be an inch in diameter. Native Americans strung together the freshwater drum’s large otoliths (granules of calcium carbonate) as necklaces or bracelets.Anglers may be surprised to feel them vibrate like a cell phone. Male freshwater drum makes its unique sound with muscles rubbed along its swim bladder.It can use its high snout and forehead to flip stones and expose food. It feeds on many different types of food from crustaceans and seeds to minnows and aquatic insects. This adaptation allows the drum to pick up vibrations in the water and better locate food and enemies. A freshwater drum’s lateral line (a visible line of sense organs on the side of a fish for detecting pressure and vibration) extends to the end of its tail, which is farther than most other fish species. Other names include silver bass, gray bass, lavender bass, and gaspergou from the French casse-burgeau "to break a clam." Locally many anglers refer to them as "sheepshead."įreshwater drum like turbid water and inhabit slow or moderate current over sand or mud bottoms. That noisiness generated many colorful nicknames, including croaker, thunder pumper, grunter, grinder, bubbler. Males make a grunting or rumbling sound during the breeding season, which is thought to attract females. The freshwater drum is a fish known for its noise. Fish of the Mississippi River Introduction

![]() I also want to reference this post as a deep dive into a lot of my struggles for those who want to see other photos and read a bit more about my past testing / current setup I will have 1 stock filter, 1 modded filter, and be able to adjust things to test what really works well and what fixes issues (or adds more). I am going to be modding the filter and adding those parts into the existing setup one by one. Right now I have a newly purchase Tidal 55 for the new tank. I've used everything from the 35 to the 75 for a few years on each model in a variety of tank setups. I also have my own experiences and testing, mods, and attempts to fix this issue previously on 5-6 versions of this product. I am setting up a NEW 29G aquarium in the living room, and I have the video above as a template. Once you get the hang of it, there isn't much difficulty and it can easily be done with a pair of scissors in between a water change. This means that cutting sponge can be tricky, but it's very easy to achieve this. the media box itself opens up as it increases in height. Second to this issue, as you add more layers of sponge, each layer needs to have a slightly larger dimension outward. As mentioned above there is often some gaps out of the box. Normally I prefer to run 2 sponges, but there is often an issue with the seachem products. Right now, after a deep clean I can see bypass almost immediately with a stock sponge. Realistically this does not fix anything, but it really does give you a bit more time for the basket to do it's job. If we swap this foam out with "bumpy foam" you see a bit of room for the water to flow into the filter basket. ![]() So, if we take a look at what is really going on internally we see the standard foam (right side above) which sits flush against the openings. From the typical "pond foams" that you can purchase for filter mods with the bumps you'll end up with something that is slightly thinner in profile and this might also be easier to compress when loaded with heavy media. What I have realized is that by adding more media or adding crushed coral in the basket, this compresses the sponge into these grates and emphasizes the bypass even further. It also gives the sponge itself a flat surface to rest on, somewhat. The basket does have "baffles" or sort to hold up the sponge and this is partly just due to manufacturing and wanting to have a clean edge and encourage flow internally. This also means we might be able to use something like eheim mech (thanks pondguru for the idea) to diffuse the flow itself. If Seachem feels like it, they can resolve issue #3 by adding some baffles in this space. There is a bit of space below the basket itself. If we look at the filter box itself and the basket, this is what we see. Let's take a look at why this helps and what is really going on. For the Tidal 35, this alone has resolved most of the bypass issues and has given me a few notes. Simply cutting new sponges that allow water into the basket itself. I want to attack these 1 by 1 and demonstrate each of these, but I will do this in a follow up post.įirst up we have the easiest thing we can do. Because of flow strength, media order, and bottom to top flow design, it's difficult to use something like purigen because of the high flow / bypass that forces lighter media off the top of the media basket and into the tank itself fairly easily. The filter basket design is very restrictive and tolerance on sponges is often undersized, which caused bypass when you do manage to get the water into the filter media basket.ĥ. the flow into the HoB filter basket can cause bypass simply due to the flow strength. The pump is incredibly strong and might be too strong in some instances. The flow path of the water itself in the pump is not well defined and the water constantly avoids filter media and filtration.ģ. The reduces the viability of something like an intake sponge and causes many issues for nano fish, flat bodied fish, or plants being sucked into the intake.Ģ. There is an excess of openings on the intake and this forces most of the intake of the filter to be provided via the skimmer, pump housing cover, and minimally from the inlet pipe itself. 8/1/2023 0 Comments Compare cities based on salary![]() We love to say you can work from anywhere - we have no borders, no “market,” and yet market rate remains a compensation factor. Remote companies are decidedly, proudly indifferent to geography. Code written in Thailand has the same value as code written in San Francisco it works the exact same for end users, and it’s just as easy for teammates to read/review. In a software business, geography plays no role whatsoever in determining the intrinsic value of the work. I’m borrowing a phrase typically used to describe the pay gap associated with underrepresented groups, but the same principle applies here.Īll of the remote companies mentioned above - Help Scout included - are software companies. I’d like to posit another option, which is also grounded in fairness: Equal pay for equal work. A different approach: equal pay for equal work My goal is not to criticize anyone - it is to ask an honest question: Is this the right approach? Because it doesn’t feel right to me. These examples are how most remote companies operate, and to repeat, they have the best of intentions and aim to be fair to employees. “We remain efficient financially if we are hiring globally, working asynchronously, and hiring great people in low-cost regions where we pay market rates.” They go on to say as much elsewhere in their handbook: ![]() Each division and department in the company has a “target” location factor they are looking to achieve, I’m assuming for budgetary purposes. Gitlab’s average location factor across all teams is 0.679, which means the average employee compensation is 67.9% of what an employee in San Francisco would be paid. This is not a cost of living analysis, but instead a cost of market evaluation compared to San Francisco.” “Location Factor is calculated using multiple data sources to conduct a market analysis of compensation rates globally: Economic Research Institute (ERI), Numbeo, Comptryx, Radford, Robert Half, and Dice. Gitlab gets more scientific in the way they think about market rate: Our approach was similar to Buffer’s, who has a transparent salary calculator with three simple cost of living options for each role: low, average, and high. For several years, the formula included a cost of living variable to determine a “fair market rate.” People who lived in a city with a high cost of living would be paid more, and we used tools like this one from CNN and this one from Numbeo to make the determination. Like many remote-first companies, Help Scout employees are paid based on a salary formula that’s transparent to everyone in the company. But regardless of the intention, I believe it’s the wrong approach. It’s logical, rooted in good intentions, designed for transparency, and optimized for fairness. A best practice has emerged among remote companies: variable pay based on the employee’s geographic location. |
