Current and future assisted reproductive technologies for fish species

Area of Science:

• Aquaculture and Fisheries Science
• Reproductive Biology
• Animal Science

Background:

• Global aquaculture production is projected to exceed capture fisheries, marking a significant shift towards fish farming.
• While many farmed fish species are partially domesticated, few are based on improved lines or independent of wild seedstock.
• The aquaculture industry is relatively young, with reproductive technologies historically focused on completing life cycles in captivity.

Purpose of the Study:

• To discuss reproductive technologies developed for aquaculture.
• To examine the implementation of these technologies across various aquaculture sectors.
• To explore future directions for reproductive technologies in finfish aquaculture.

Main Methods:

• Review of reproductive technologies applied in finfish aquaculture.
• Analysis of the implementation and impact of these technologies.
• Discussion of case studies and future research trends.

Main Results:

• Reproductive technologies have been crucial for increasing seed production and initiating fish domestication.
• Technologies enable control of gender, maturation timing, and sterilization, optimizing growth and flesh quality.
• These advancements address challenges like sexually dimorphic growth and genetic containment in farmed fish.

Conclusions:

• Reproductive technologies are vital for the advancement and sustainability of the finfish aquaculture industry.
• Further development and application of these technologies are essential for future growth and efficiency.
• Strategic implementation of reproductive technologies will drive innovation in fish farming practices.
