এটি সুইজারল্যান্ডের একটি অসাধারণ ফিশ ল্যাডার বা মাছের সিঁড়ি। সচরাচর বাঁধগুলো মাছের স্বাভাবিক চলাচলে বাধা সৃষ্টি করে, বিশেষ করে যখন তারা ডিম পাড়ার জন্য উজানের দিকে যায়। এই ফিশ ল্যাডার সেই সমস্যারই একটি কার্যকর এবং বিজ্ঞানভিত্তিক সমাধান।

এই কাঠামোটি এমনভাবে তৈরি করা হয়েছে যাতে এটি একাধিক ছোট ছোট জলাধার বা ‘ধাপ’ নিয়ে গঠিত হয়। প্রতিটি ধাপের উচ্চতা এমনভাবে নির্ধারণ করা হয়েছে, যেন মাছগুলো সহজেই এক ধাপ থেকে অন্য ধাপে লাফিয়ে উঠতে পারে।

জলাধারগুলোর মধ্যে জলের প্রবাহ নিয়ন্ত্রিত থাকে, যা মাছকে উজানের দিকে সাঁতার কাটতে উৎসাহিত করে এবং প্রয়োজনীয় শক্তি যোগায়। এর ফলে, বাঁধের কারণে সৃষ্ট বাধা সত্ত্বেও মাছগুলো তাদের প্রাকৃতিক প্রজনন ক্ষেত্রে পৌঁছাতে পারে এবং তাদের জীবনচক্র নির্বিঘ্নে সম্পন্ন করতে পারে।

এটি কেবল মাছের মাইগ্রেশনে সহায়তা করে না, বরং জলজ বাস্তুতন্ত্রের ভারসাম্য বজায় রাখতেও গুরুত্বপূর্ণ ভূমিকা পালন করে।
