" The Significance of Sturgeons in Human Culture "
 

Sturgeon is a type of large primitive fish belonging to the family Acipenseridae. They are known for their slender bodies, scale-less skin, and rows of bony plates called scutes. Here are the physical characteristics of sturgeons:


- Body shape:  Sturgeons have a long and slender body, typically with a cylindrical-shaped back and a flattened belly. Their bodies can sometimes be slightly laterally compressed.

- Fins and tail:  Sturgeons have a pair of dorsal fins and ventral fins located above and below their bodies, respectively. The dorsal fin is usually positioned in the middle or slightly towards the back, while the ventral fins are located on the belly. Additionally, sturgeons have large and robust tails, often  forked in shape.

- Scutes:  The body of sturgeons is covered with a series of large and hard bony plates called scutes or ganoid scales. These scutes are typically diamond-shaped or pentagonal and arranged in rows, providing protection for the sturgeon's body.

- Rostrum:  Sturgeons have an elongated and pointed structure extending from their heads, known as the rostrum. The rostrum is located at the bottom of the mouth and is used to detect and search for food during foraging.

- Skin:  Unlike other fish, sturgeons have almost no scales on their skin. Instead, their skin is smooth and covered in a layer of mucus, giving it a wet and slightly slippery texture.

 

These morphological traits set sturgeons apart from other fish species, and their antique look attracts scientific attention and respect. However, the exterior characteristics of sturgeons might change across species and individuals, as well as specialized attributes.

Sturgeons have been around for hundreds of millions of years, making them one of the oldest fish species on the planet. Sturgeons originated in the Northern Hemisphere and are now found all over the world in rivers, lakes, and coastal waterways. Sturgeons have great cultural and economic relevance in ancient civilizations. Sturgeons were regarded sacred fish in civilizations such as Ancient Egypt, Ancient Greece, and Ancient Rome, and were connected with plenty, longevity, and supernatural abilities.

Sturgeons are bottom-dwelling migratory fish with omnivorous diets and lengthy lifespans. They move to spawning sites and feed in various seasons and bodies of water. Sturgeons, being bottom-dwelling creatures, prefer to forage in riverbeds or on the seafloor, largely eating on benthic invertebrates, fish eggs, and plankton. Sturgeons are notable for their longevity, with individuals frequently surviving for 50 to 60 years and only beginning to spawn at 15 to 20 years of age. They do not spawn every year because they require certain environmental conditions such as a suitable spring light cycle, clear water, and gravel riverbeds. A sturgeon may lay up to 3 million eggs at once, although not all of them will hatch.

Sturgeon holds significant importance for humans in multiple aspects. Firstly, as a precious ingredient, sturgeon meat and caviar are beloved delicacies that provide people with unique tastes and flavor experiences. Caviar, made from sturgeon roe, is especially regarded as a gourmet delicacy on upscale dining tables. Secondly, sturgeon observation activities attract a large number of tourists, contributing to the economic benefits of the tourism industry and promoting the development of ecotourism. Additionally, as an ancient species, sturgeon provides valuable data for scientific research, aiding in deepening our understanding of biological evolution, ecosystem interactions, and environmental conservation. Finally, as an indicator species of ecosystems, sturgeon plays a role in monitoring and assessing the health of aquatic environments. Protecting sturgeon helps maintain species diversity and ecological balance. Therefore, preserving sturgeon habitats and species and adopting sustainable management measures are of significant importance for human culinary culture, tourism industry development, scientific research, and environmental protection.
 

Sturgeon aquaculture has a lengthy history, dating back to ancient times when people experimented with artificial reproduction and sturgeon rearing. However, contemporary sturgeon aquaculture techniques were mostly developed in the twentieth century. Sturgeon eggs and flesh were already frequently gathered and consumed in ancient times. However, the genuine improvement of sturgeon aquaculture techniques may be traced back to the late nineteenth and early twentieth centuries, with the first sturgeon aquaculture experiments taking place in Russia, France, the United States, and other places. The Soviet Union emerged as a pioneer in sturgeon aquaculture in the 1950s, ushering in a new era for the business.

 

Artificial reproduction, incubation, fingerling raising, and farming are the mainstays of modern sturgeon aquaculture techniques. Artificial reproduction encourages sturgeon to produce eggs by imitating natural spawning circumstances in the wild, after which the eggs are collected for incubation. To guarantee effective hatching of the eggs into larvae, the incubation procedure entails maintaining water temperature, water quality, and supplying adequate nourishment. The fingerling raising stage necessitates rigorous management, including the provision of appropriate nutrition and growth settings to ensure the healthy development of young fish. To guarantee the health and growth of sturgeon, attention must be paid to water quality management, feed delivery, illness prevention, and control during the farming process.

Aquaculture, on the other hand, has a number of obstacles and issues. To begin with, sturgeon reproduction is difficult, with high demands for environmental conditions that must resemble the natural habitat. Second, the slow development rate of sturgeon often takes several years, if not more than a decade, to reach commercial sizes, needing long-term investment and administration. Furthermore, illness prevention and management are key issues in sturgeon aquaculture since sturgeon are sensitive to a variety of diseases that need suitable preventative and therapeutic strategies.

One of the most crucial components in the complicated environment of sturgeon aquaculture is maintaining consistent and high-quality water. This explains why Ecowater is so crucial.
