Bangladeş'in Güneybatı Bölgesindeki Kıyı Bölgesinde Yavru Karideslerin (P. monodon) Ayrım Gözetmeksizin Tüketilmesinin Su Yaşamı Üzerindeki Etkileri

Öz

Yavru karides ( Penaeus monodon) avcılığı, tüm yıl boyunca Bangladeş'in güneybatı kesimindeki kıyı bölgelerindeki çoğu balıkçı için önemli bir gelir kaynağıdır. Bu larva sonrası evredeki yavru toplayıcılar finansal güvenceden yoksunlar ve sosyal durum olarakta gerilemekteler . Diğer su türleri de, yavru karideslerin su ürünleri yetiştiriciliği amacıyla ayrım gözetmeksizin kullanılması nedeniyle yok edilmektedir. Mevcut çalışmamız göstermektedir ki ortalama olarak %0,35'i Penaeus indicus, %0,06'sı Penaeus merguiensis, %0,037'si Metapenaeus monoceros, 3,58'i diğer karides, %6,59’u yüzgeçli balık larvası, %5,95’i yengeç larvası ve %82,42’si küçük organizmalar olmak üzere, araştırma alanımızda gelişigüzel kullanılan yavru karideslerin yaklaşık %1-2'sini yakalamak için diğer larvaların yaklaşık %98-99'u yok edilmektedir. Aslında Bangladeş hükümeti hali hazırda bir yasak dönemi beyan etti ve yavru karides avcılığını yasadışı ilan etti. Ama yoksul balıkçılar geçimlerini sağlamak için avcılığa devam etmektedirler . Ayrıca yabani yavru karideslerin, kuluçkahanelerde yetiştirilen yavru karideslere göre çok daha yüksek hayatta kalma oranına sahip olması sebebiyle , balık çiftçileri yabani yavru karidesleri tercih ediyor. Yabani yavru karides avcılığı, Bangladeş kıyılarındaki binlerce topraksız ve işsiz yoksul insan için istihdam fırsatları yarattı. Bu çalışma, Bangladeş'in kıyı bölgelerinde yabani yavru karides avcılığının etkisini açıklamaktadır.

Impacts on Aquatic Life for Indiscriminate Exploitation of Baby Shrimp (Penaeus monodon) in the Coastal Area, South-Western Region of Bangladesh

Abstract

Baby shrimp ( Penaeus monodon) post-larvae fishing is a major source of income for the most fishermen in the coastal region of the south-western part of Bangladesh during the whole year. These post-larvae collectors lack financial security and are socially regressive. Other aquatic species are destroyed by the indiscriminate exploitation of baby shrimp for aquaculture. According to the present study, about 98-99% of other larvae are destroyed to catch nearly 1-2% of indiscriminate exploitation baby shrimp in our study area where averagely 0.35% Penaeus indicus, 0.06% Penaeus merguiensis, 0.037% Metapenaeus monoceros, 3.58% other shrimp, 6.59% fin-fish larvae, 5.95% crab larvae, and 82.42% small organisms. Actually, the government of Bangladesh already has declared a ban period and outlawed baby shrimp fishing. However, the poor fishermen are fishing continuously in order to maintain their 's livelihood. Furthermore, because of wild baby shrimp are said to have a far higher survival rate than baby shrimp raised in hatcheries, farmers prefer wild baby shrimp. For thousands of Bangladeshi coastal landless and jobless poor people, wild prawn baby shrimp fishing has created employment opportunities. This study describes the impact of wild baby shrimp fishing in coastal area of Bangladesh.
