Abstract:
... Feeding regime, which involve selection of appropriate diet and application of feed itself is a decisive factor in intensive, RAS-based production system – more so, for carnivorous fish culture. It is critical for the economics, resource (feed/nutrients) use efficiency and final profit yield. The present study examined different feeding strategies in juvenile pikeperch reared in RAS for growth per ...

Abstract:
... For sustainable aquaculture, the replacement of dietary fishmeal with plant protein is becoming more common because fishmeal resources are limited. However, in the case of carnivorous fish such as yellowtail (Seriola quinqueradiata), reducing the dietary fishmeal level often causes low feed intake. Improving feed intake is important in the use of a non- and low-fishmeal diet. However, little is kn ...

Abstract:
... Aquaculture is the fastest growing agricultural sector in the world, and the annual aquaculture production reached 82 million tonnes in 2018. Fish feed is the most expensive component of aquaculture. The partial replacement of commercial fish feed with biofloc was evaluated as a dietary ingredient in feed for barramundi (Lates calcarifer), a high-value carnivorous fish. Biofloc was produced from t ...

Abstract:
... Carnivore populations globally have largely declined, and coexistence, where humans and carnivores share landscapes, plays a crucial role in carnivore conservation. However, the term “coexistence” is often used in scientific and popular literature without being clearly defined. Herein, we provide a global perspective on what coexistence is and how it is studied. We conducted a systematic map of 36 ...
