110年12月5日鰻苗捕撈概況

 110年12月5日鰻苗捕撈概況

節錄自<日本養殖新聞>

⃝昨晚漁獲量更少了，南北加起來只前一天的一半6000尾!!

台灣期待的暗夜大潮(2-7號)，還沒有一天有超越二位數的漁獲，這波大潮可能就這麼過了。業者說「前天抓到的鰻苗，並沒有新的苗，只有老的苗。昨晚也是一樣，完全沒有像樣的漁群，這波潮水就這麼結束了。」

昨晚北部宜蘭縣的捕苗船約有40艘出海作業。不過，跟前天晚上一樣，下網之後根本都抓不到，只好早早收網回港。船家說「比較努力抓的船大概有100尾，其他則只有20-30尾。這波潮水不行了，一個星期後就是小潮了。」，其他的定置網及收撈網的成績也都不行。

南部屏東縣的船還是持續抓小蝦，定置網及手撈網的漁獲也是減少的。南北加總捕撈量可能只有6000尾或更少。

Abstract

Intricate color patterns are a defining aspect of morphological diversity in the Felidae. We applied morphological and single-cell gene expression analysis to fetal skin of domestic cats to identify when, where, and how, during fetal development, felid color patterns are established. Early in development, we identify stripe-like alterations in epidermal thickness preceded by a gene expression pre-pattern. The secreted Wnt inhibitor encoded by Dickkopf 4 plays a central role in this process, and is mutated in cats with the Ticked pattern type. Our results bring molecular understanding to how the leopard got its spots, suggest that similar mechanisms underlie periodic color pattern and periodic hair follicle spacing, and identify targets for diverse pattern variation in other mammals.
