1 - Habitat Modification and Removal (Biobturbation)

Effect: This constant movement (bioturbation) removes nutrients trapped in the soil (such as phosphorus) and releases them into the water column.

Consequence: At controlled densities, this helps aerate the aquatic substrate. However, at high populations, it excessively clouds the water, reduces sunlight reaching the plants, and can cause algal blooms (eutrophication).

2 Nutrient recycling and population control:

Omnivorous diet: They act as an intermediate link in the food chain by consuming macroinvertebrates (such as insect larvae and worms), crustaceans, organic remains, seeds and algae.

Phosphorus release: By disturbing the bottom, trapped nutrients (such as phosphorus and nitrogen) are released into the water column, which stimulates phytoplankton growth.

3 - The great dilemma: Its impact as an invasive species: Although they maintain a balance in their native Eurasian habitats, carp have been introduced worldwide (including Mexico and the rest of the Americas) and are considered one of the 100 most harmful invasive alien species in the world. When their population gets out of control, their "function" becomes destructive.

Native displacement: They compete fiercely for food and devour the eggs of native fish, completely altering local biodiversity.

Water turbidity: Its constant excavation generates high turbidity (muddy water), which prevents sunlight from penetrating and destroys aquatic photosynthesis.

Destruction of flora: They uproot and devour aquatic plants that serve as natural filters and refuge for other species.

How do you determine the real age of a carp?
1 - Facial features: The heavy head and drooping or "wrinkled" lips mimic the physiognomy of an old animal or an old record carp (commonly known in fishing culture as typical of old or past specimens of their usual reproductive stage).
2 - Extreme body size: The fish displays a massive body condition and an extremely bulging abdomen that mimics the flabbiness of old age. In nature, carp exceeding 15 kg are usually at least 10 years old, and truly gigantic and robust specimens are often "old legends" of the lakes.
3 - Scale reading: Just like the rings of a tree, carp scales form annual rings called annuli due to growth changes between winter and summer.
4 - Otoliths (Ear Bones): This is the most precise scientific tool. By extracting these small internal bones from the fish, they can be cut into thin slices and their growth bands counted under a microscope.
5 - Fin rays: Analyzing cross-sections of the hard rays of the pectoral fin serves as an alternative method that does not lethally harm the fish.

appearance: it's a carp.
breed: mirror carp.
Additional information: very bulky.
It measures: 1.25 meters long and about 22 centimeters wide.
It weighs: 40 kilos
Intelligence: minimal; a fish is guided more by instinct than anything else.
personality: well I doubt it has a personality and if it does I think it's only by association with a food source.
Age: Between 15 and over 25 years old, the exact age is unknown.
