Annotatsiya: Baliqlarni barcha suv havzalarida uchratish mumkin. Masalan
ko‘llarda, daryolarda, dengizlarda, okeanlarda, suv havzalarida. Bugungi kundagi,
hisob-kitoblarga ko‘ra, dunyo bo‘ylab 32000 dan ortiq turli baliq turlari mavjud.
Baliqlar orasidagi ularning kattaliklari turlicha bo’ladi. Xususan, eng kichik Kiprinid
baliqning uzunligi atigi 7 santimertni tashkil qiladi, eng yiriklari esa Kit akulasi 9
metrdan ortiq uzunlikdagi dunyodagi eng katta baliqlardan biridir. Insonlar
tomonidan ovlagan baliqlar miqdori juda hayratlanarli ahvoldadir. Masalan, 2021
yilda taxminan 110 million tonna baliq ovlangan. Odamlarning haddan tashqari baliq
ovlashi va dengiz ekotizimini beqarorlashtirishi tobora oydinlashmoqda. O'tgan asrda
akulalar kabi yirtqich baliqlar populyatsiyasining uchdan ikki qismidan ko'prog'i ham
kamaydi. Umuman olganda, qaysi dengizda bo'lishidan qat'iy nazar, ham biologik
xilma-xillik, ham ko'plik kamaygan ekotizim kuzatilmoqda.

Abstract: Fish can be found in all bodies of water: lakes, rivers, seas, oceans,
ponds. Today, there are an estimated 32,000 different fish species worldwide. There
are fish by size. In particular, the smallest Cyprinid fish is only 7 centimeters long,
while the largest, the Whale shark, is one of the largest fish in the world, more than 9
meters long. The amount of fish caught by humans is astonishing, with about 110
million tons of fish caught in 2021. It is becoming increasingly clear that people are
overfishing and destabilizing the marine ecosystem. Over the past century, more than

two-thirds of the population of wild fish, such as sharks, has declined. In general,
regardless of which sea it is in, both biodiversity and abundance are observed.
