What is the purpose of using large syringes in the collection of gametes from gonochoric species?

Using large syringes in the collection of gametes from gonochoric species is primarily aimed at collecting gametes in situ. Gonochoric species are those where individual organisms are either male or female, and during spawning, they release gametes into the surrounding water. Collecting these gametes directly in their natural environment ensures that the timing and conditions are optimal for gathering high-quality samples.

The use of syringes allows for a controlled and efficient way to collect the gametes without significant disturbance to the surrounding habitat. This method is especially important for coral restoration efforts, where the success of fertilization and subsequent larval development is highly dependent on the timely and precise collection of these reproductive materials.

While enhancing fertilization rates and extracting biomass are also important aspects of coral restoration, these do not pertain specifically to the function of large syringes in the context of in situ gamete collection. Measuring water quality, while crucial in the broader context of marine biology and conservation, is unrelated to the primary function of using syringes for gamete collection.
