Fish ladder

Mekong and its Effect on Fish Migration in Thailand Dams have many purposes, such as storing water in order to combat fluctuations in river flow or demand for water, raising the water level so that the water can be directed to flow into a canal to generate electricity, control flooding, and provide water for agriculture, households and industries (Silvia, 1991). With an increase in demand for cleaner sources of energy, many countries have turned to damming as a solution. The Southeast Asian countries that the Mekong river flows through have recently become increasingly interested in damming the Mekong river.…

vegetation dying, fish migration, and the buildup of toxins. These problems cause unnecessary harm the surrounding ecosystem and sometimes unrepairable damage to the earth, which appeal to the moral principles of not causing more harm than necessary and leaving the earth in an as good as or better condition. To repair the damage caused by dams, the US government should repair or remove dams that have under 75% efficiency because the modern dams on average can…

After crossing the second trampoline, it was time to climb back up another slanted wall with a rope ladder attached to it and then back down a final ladder wall and off the Antigravity obstacle. The course continued on a very brief distance and up next was “The Warped Wall” obstacle, which was a very challenging warped wall. I was able to make it up the wall on both days without assistance, but the volunteers where awesome and very quick to offer any racers assistance if they needed help with…

generally used for fish that jump like salmon or trout this type of ladder are used for larger dams they are susceptible to water elevations. Denil ladder have more pools in comparison to other fish ladders they also act similar to rapids with different rates of water flow allowing different types of fish to travel up and down streams this type of fish ladder are less sensitive to elevation and are more well-rounded for both big and small dams. Steep passes are similar to Denil in the way of…

Each year, more people die from bee stings, snakebites, falling off ladders, or drowning in a bathtub than from a shark attack. Yet, people still think sharks are frightening and vicious killers. Sharks main prey are not humans, they usually eat smaller sea creatures. It is more likely for a swimmer to be struck by lightning than attacked by a shark. Many shark attacks that occur on a human are accidental. Sharks are not vicious killers as portrayed in the movies like Jaws. Most people are…

negative impact on water consumption and the fish species. Knight and Rummel attempt to explain the pros and cons of dams. The movie also features the tale of salmons, which are unable to return to their original spawning grounds due to dams. These create issues for fish companies, the hatcheries that go at a loss due to reduction of number of fishes. The documentary advocates for change in the United States of America…

except for the beaches and national parks are covered in trash. The reason the beaches are not covered in trash is because the maid drones throw their trash in the water. It’s so disgusting! I poked my head above the water and a maid drone threw trash at me. Then I remembered I could do something about it. I decided to go turn on The Filter. The Filter is a giant machine in the middle of The Gulf of Mexico. It looks like an oil platform but it is 30 times bigger. The Filter cleans the…

We’ll be back soon okay?” Cable said. “If you need the gun, it’s under the blanket.” I nodded. He climbed up the ladder that led to the deck. I walked to the blanket and lifted it up. A flare gun was resting under the blanket. “Well hopefully I won’t need it!” I shouted to Cable. Cable chuckled. “I hope not.” Cable zipped up his bag and threw it onto his shoulder. I lifted the blanket up and set the gun inside gently. I sighed. I dropped the blanket on top of the gun. I climbed up the ladder…

started to climb up the ladder to the roof; I quietly threw a rolled up wad of cash next to the chef, who was cutting meat. He didn’t look at me, he just paused for a moment, then nodded. I climbed up to the roof behind them, pulled out my gun and checked the allies below to make sure no one knew we were there. Mr. Blonde and I had rifles on our backs, while Mr. White had a shotgun. We didn 't have them out then because they were too long, we all had out handguns. We jumped the roof to the next…
