Which fish is bigger male or female?
In over 80 per cent of fish species, the females, including those known as ‘big old fecund females,’ or BOFFS, grow bigger than the males. This long-established fact is difficult to explain with the conventional view of fish spawning being a drain on the ‘energy’ available for growth.
Why male tilapia grow faster than female?
Growing only male fish
Male tilapia grow faster than females because all their food is used for growth only. 363 If you decide to grow male fish only, use fish at least 12 centimetres long because they are already big enough to sex. A male fish of this length can reach 200 to 250 grams within six months.

They grow the fastest as compared to other species and can gain up to three to four pounds in a year.
What makes tilapia fish grow faster?
Food and oxygen availability
Food and oxygen are two of the most critical factors that dramatically contribute to the tilapia growth rate. Since tilapia is mainly herbivorous, feeding them an adequate amount of plant-based food will quickly help them reach their mature size.
How fast do tilapia reproduce?
How Quickly Do Tilapia Reproduce? The average tilapia spawns babies every 4 weeks to 16 weeks, depending on the species. Even if you don’t separate the babies and some are eaten, you’ll still end up with more tilapia than you started with in a short period of time.
How many times do tilapia lay eggs?
Mature females can lay eggs every three to four months (from the 12th week in the case of the Nile tilapia). They lay their eggs in nests made by the males, then carry the fertilised eggs in their mouths until they hatch.
How many months do you harvest tilapia?
Fish are harvested after 3-5 months of culture when fish are 100-200 g. The success of tilapia farming in the coun try may be attributed to the suitability of the fish to Philippine conditions, the locally developed technologies for production, and the presence of a vibrant market.
Are male fish smaller than female?
Males are often slimmer but larger-bodied than females and are more vibrantly colored. The dorsal and anal fins of the male are more pointed, larger, and more flowing than in the female. In many species, the male will display egg-shaped markings on the anal fin known as egg spots.
Are female fish larger?
In over 80 per cent of fish species, the females, including those known as ‘big old fecund females,’ or BOFFS, grow bigger than the males.

What is genetically male tilapia?
These males are termed as “genetically male tilapia” (GMT) and are separated from sex reversed male tilapia (SRT) and normal males. The GMT are all- male and supposed to have higher growth, delayed maturity and higher production than other types of male fish.
Can fish change their gender?
Researchers have identified more than 500 fish species that regularly change sex as adults. Clown fish begin life as males, then change into females, and kobudai do the opposite. Some species, including gobies, can change sex back and forth. The transformation may be triggered by age, size, or social status.
