[ AQUACULTURE ] Biomark provides advanced technology solutions for broodstock management

Marrying technology with genetics to breed better fish Broodstock management lies at the heart of successful aquaculture production. Fish that better meet market demand are produced through generations of strategic breeding. Regardless of species or location, monitoring broodstock success requires careful analysis of breeding efforts and the ability to trace offspring.

FID technology or PIT tag implantation is a popular solution for broodstock management. The ability to track individuals throughout their lifecycle is an effective strategy for observing the heritability of traits related to survival, growth, disease resistance, fecundity, etc. By incorporating genetic data with RFID tracking, managers can identify target genotypes associated with desirable traits, and then optimise breeding strategies to ensure the expression of those desirable traits in the hatchery population. The use of PIT tag unique identifiers is critical to separating fish with traits that foster successful stocks.

PIT tags for a variety of applications and budgets Biomark offers a suite of Passive Integrative Transponder (PIT) tags that are a reliable, longlasting (no reliance on battery power), and an effective low-profile technique for associating vast amounts of data to individual fish. These tags provide 100 unique 1 2

identification (ICAR certification, ISO Standard 134.2 kHz tags) and are the highest performing RFID tags on the market today for use in fisheries, aquaculture and wildlife research and monitoring. Tags are available in different sizes,

performance levels and packaging options to meet a variety of application needs and budgets. The smallest solution, the 8 mm HPT tag, has proven effective in fish as small as 45 mm in fork length, with no visible effect on

behavior and growth1, 2, 3, 4. In larger species, the 12 mm APT tag is a common solution for tracking individuals and their offspring throughout generations, starting from 60 mm in fork length. The most common use in aquaculture
