The current global fishing capacity exceeds sustainable limits. As of 2022, the total fish production from marine capture fisheries and aquaculture reached 223.2 million tonnes. The United Nations Food and Agriculture Organization reports that 34.2% of fish stocks are overfished, highlighting the urgent need for sustainable practices. In addition, illegal, unreported, and unregulated (IUU) fishing … Read more

Betta fish prefer water temperatures between 76°F and 81°F (24°C to 27°C). They can tolerate short bursts up to 85°F (29°C). However, temperatures above 86°F (30°C) for too long can be harmful. Extreme temperature changes can stress them. Maintaining the ideal range keeps betta fish healthy and active. High temperatures can lead to decreased oxygen … Read more

Betta fish thrive in water temperatures between 75-82°F (24-28°C). This ideal range supports their health and metabolism. Temperatures exceeding 86°F (30°C) can cause stress. Use a heater to maintain this range, as extreme temperatures can weaken their immune system and increase disease susceptibility. If the water temperature exceeds 86°F (30°C), it can become dangerous for … Read more

Keeping marine fish is harder than keeping freshwater fish. Marine aquariums need careful water chemistry, special equipment, and consistent maintenance. Success requires patience, research, and a budget for costs. With careful planning and effort, anyone can enjoy this rewarding hobby. Next, understanding water quality is crucial. Marine fish require stable salinity, temperature, and pH levels. … Read more

A betta fish can swim up to 3 miles per hour for short distances. They show varied swimming patterns and explore their tank while taking breaks. Healthy bettas are energetic and agile. Factors such as tank conditions and water quality greatly influence their behavior and swimming speed. Proper aquarium care supports their health. In addition … Read more

Betta fish can see up to 30 centimeters in clear water. Their eyesight weakens in darkness because of slow iris movement and limited color vision. Bettas sense vibrations and often recognize their owners, swimming toward them when they approach. They show excitement in familiar tank settings and exhibit common behaviors like curiosity and exploration. In … Read more

Water temperature affects fish respiration by influencing their metabolic rate. Higher temperatures raise the metabolic rate, increasing oxygen demand. This can lead to lower levels of dissolved oxygen (DO). In warmer water, fish may experience increased stress and more rapid gill movements, which can affect their foraging and survival rates. Temperature changes also impact fish … Read more

Water temperature significantly affects fish because they are ectotherms. Warmer water raises their metabolic rate, causing a higher need for oxygen, which is less available. This can lead to slower movement, lower appetite, and stunted growth. Colder water slows metabolism and reduces food needs, influencing their behavior and overall health. Behavior also shifts with changing … Read more

Salinity affects fish growth, survival, and reproduction. Freshwater fish can struggle in high salinity levels, leading to death. Low salinity aids larvae and fry development. Fish adjust their physiological processes, like osmoregulation, to maintain homeostasis, which influences their metabolism and overall health. Additionally, tolerance to salinity varies among species. Some fish, like euryhaline species, can … Read more

Commercial fishing greatly impacts marine life. Overfishing depletes fish stocks and bycatch kills many non-target species, including marine mammals. Unsustainable fishing practices harm habitats like coral reefs and seagrass beds. This disrupts biodiversity and the food web, threatening marine ecosystems and aquatic life. Bycatch is another concern. Bycatch occurs when unintended species are caught during … Read more
