Longline fishing uses long lines with many baited hooks. This method often catches non-target species, called bycatch. Fish like swordfish and tuna are commonly targeted. The large catch volume can harm marine organisms and disrupt ecosystems. This raises concerns about ecological impact and the need for sustainable fishery management practices. The consequence is a sharp … Read more

Industrial fishing harms marine ecosystems by reducing fish populations. Overfishing disrupts the food web and causes an imbalance. It threatens biodiversity and impacts vulnerable species like sea turtles and coral reefs. The decline of essential species endangers overall marine life and health. Additionally, industrial fishing practices such as trawling damage ocean floors. Trawlers drag heavy … Read more

High salinity affects fish by disrupting their osmoregulation and metabolism. It can reduce fish growth and impair reproduction, including egg fertilization. Freshwater fish face stress in high salinity, increasing mortality risks. While moderate salinity may help larvae survival, too much salt weakens their immune system and overall health. Behavioral changes are also prevalent in fish … Read more

The Gonadosomatic Index (GSI) shows ovary maturation in fish. For Male and Female M. gulio, GSI increases from March, reaching its highest point in July. After July, GSI values gradually decrease until December. This cycle reflects the seasonal reproductive patterns of M. gulio (Sarker et al., 2002; Islam et al., 2008; Lal et al., 2016). … Read more

During the breeding season (June-August), fish gonad size changes significantly. Males’ testes grow larger while females’ ovaries expand, causing noticeable belly size increases. Hormone injections stimulate spawning. The selected broodstock shows size differences based on species, reproductive organs, and readiness, influenced by plasma FSH levels. Females may also exhibit size changes, primarily to nurture more … Read more

Overfishing harms marine ecosystems by removing too many fish, creating an imbalance in the food web. This threatens vulnerable species like sea turtles and corals. Healthy fish populations are vital for maintaining biodiversity and ensuring ecosystem stability in marine life. Bycatch, the unintentional capture of non-target species, poses another concern. This practice devastates populations of … Read more

Overfishing affects marine ecosystems by removing too many fish. This disrupts the ecological balance and harms the food web, reducing biodiversity. Vulnerable marine species, like sea turtles and corals, are particularly at risk. Adopting sustainable fishing practices is vital for protecting these habitats and supporting fish populations. Moreover, fishing alters habitats. Methods like bottom trawling … Read more

A current affects fishing by improving bait movement and attracting fish. It disrupts hiding spots and creates pockets of concentrated bait. Fish often gather in moving water, making currents essential for effective fishing strategies. Always look for these areas to increase your chances of success when fishing. Fish behavior also changes with current flow. Fish … Read more

Crappie rates highly on the taste scale for freshwater fish. It has delicate, sweet flesh that many people enjoy. Compared to other panfish, crappie is popular for its mild flavor. This makes it great for cooking methods like frying and baking. Overall, crappie is one of the best-eating fish in freshwater. In comparison to other … Read more

Fish use countercurrent exchange in their gills for efficient oxygen absorption. Oxygen-rich water enters through the mouth and flows over the gills. Capillary blood in the gills moves in the opposite direction to the water. This setup enhances the extraction of oxygen from the water, supporting respiration. As water passes over the gills, oxygen diffuses … Read more
