  • What’s the difference between farmed and wild-caught seafood?
    Wild-caught seafood comes from natural environments like oceans, rivers, and lakes, offering a more diverse and sometimes richer flavor profile. Farmed seafood is raised in controlled conditions, which ensures consistent quality, availability, and lower impact on wild populations. Both options are safe and nutritious, though flavor and texture can vary slightly.
  • How do you ensure the freshness of your seafood?
    At Costi Bros Seafoods, we maintain strict quality control measures by receiving daily deliveries of fresh seafood and keeping it stored in cold, controlled environments. Our handling processes, from catch to counter, follow best practices to preserve freshness, ensuring the seafood remains in peak condition until it reaches you.
  • Do you offer both fresh and frozen seafood options?
    Yes, at Costi Bros Seafoods, we offer an extensive selection of fresh seafood daily, along with frozen options for those who prefer to stock up or need convenience.
  • How should I store fresh seafood at home?
    To keep your seafood fresh, place it in the coldest part of your fridge (between 0-2°C) and consume within 1-2 days. If you need to store it longer, wrap it tightly in plastic wrap or foil and freeze it. Frozen seafood can last up to 3 months without significant loss of quality.
