About Sponge farming

Sponge farming is a relatively new business opportunity that does not harm the marine environment.
A sponge is a living animal which is made of loosely arranged cells that surround a skeleton of fibres.
The specialised cells nestled within thousands of tiny chambers act as microscopic pumps, and tirelessly drawing water into the sponge’s body with their whip-like tails.
Sponges provide homes for many other animals, plants, and microorganisms. In many cases, they all work together in a mutual symbiotic relationship.
Sea sponges exist in all oceans around the world and make up 20% of the global silicon biological sink.
This unique pumping mechanism, which helps sponges extract nutrition and oxygen, also purifies the ocean water by removing impurities, including sewage.
Uniqueness: Sponges, unlike seaweed, possess remarkable resilience to climate change, require minimal maintenance, and command premium market prices,
Reproduction: Most sponges are hermaphrodites, harbouring both male and female reproductive organs, enabling them to self-propagate effortlessly.
New sponges emerge from small buds that detach from the parent sponge and begin independent growth.
Even damaged or fragmented sponges can regenerate into new individuals.
This remarkable regenerative ability underpins the ease and feasibility of commercial sponge farming.
Uses:
- These sponges are used for bathing and general hygiene because they are naturally antibacterial and antifungal and can resist odours.
- Research has also shown that the spongy creatures play an important role themselves in combating climate change.
- Their skeletons break down into microscopic pieces of silicon, which helps control the carbon cycle in the ocean and reduces the greenhouse effect.
- Dissolved silicon is critical for the growth of diatoms, tiny organisms which absorb large amounts of CO2 in the ocean using photosynthesis.

Q1) What is a Symbiotic relationship?

It is the close associations formed between pairs of species. They come in a variety of forms, such as parasitism (where one species benefits and the other is harmed) and commensalism (where one species benefits and the other is neither harmed nor helped).
