歡迎訂閱@Raymond2021 香港常見廣東米蝦Caridina Cantonensis棲息平靜溪床生境中,緩流帶來高氧和礦物質,有利堅固甲殼,尤其退殼期,微量礦物質顯得重要。在河溪生態中扮演初級消費者角色,牠吃分解後落葉腐植質、藻,以前鉗不斷尋找流水沖下有機屑碎。腐葉令水變酸,ph5.0-6.8,米蝦具地域性和群居習性,或在枯葉下或在溪床岩壁,以隱身逃避捕食者,體色隨地域、季節、溫度而改變,有藍、紅、金及透明,香港廣東米蝦有8種,包括三紋米蝦、蜜蜂蝦等。牠們生命美麗卻短暫,生命週期約18個月,由於對水質要求高,不宜飼養。下次,我會帶大家到龍虎山澗探索生境,我們下次再見啦! Welcome to subscribe @Raymond2021 The common Cantonese rice shrimp Caridina Cantonensis in Hong Kong inhabits calm creek bed habitats. The slow flow brings high oxygen and minerals, which is beneficial to strengthening the carapace. Especially during the shelling period, trace minerals are important. It plays the role of a primary consumer in the ecology of rivers and streams. It eats decomposed leaf litter, humus and algae. In the past, it constantly searched for organic debris washed down by running water. Rotting leaves make the water acidic, with a pH of 5.0-6.8. Rice shrimps have regional and gregarious habits. They may hide under dead leaves or on the rock walls of stream beds to avoid predators. Their body color changes with the region, season, and temperature. , available in blue, red, gold and transparent. There are 8 types of Cantonese rice shrimp in Hong Kong, including three-grain rice shrimp, honey bee shrimp, etc. Their lives are beautiful but short, with a life cycle of about 18 months. Due to their high requirements on water quality, they are not suitable for breeding. Next time, I will take you to Longhu Mountain Stream to explore the habitat. See you next time!
