Effect of substituting fishmeal with corn protein concentrate on growth performance, nutrient utilization and skin coloration in red hybrid tilapia, Oreochromis sp.

The objective of this study was to evaluate the effects of fishmeal (FM) replacement with corn protein concentrate (CPC) on growth performance, nutrient utilization, gut morphology and skin coloration of red hybrid tilapia, Oreochromis sp. the results of the present study showed that replacing up to 50% FM with CPC in red hybrid tilapia diet did not show any adverse effects on the growth performance, nutrient utilization efficiency, body-organ indices, whole-body composition, gut histology and tissue coloration of red hybrid tilapia.

Growth and economic analysis of freshwater prawn, Macrobrachium rosenbergii (de Man), produced with feeds substituting sunflower cake for fish meal, soya bean meal and mustard oil cake

Prawn farming has grown in popularity since its introduction to Bangladesh in the early 1980s and is now widely practised in coastal areas. In Bangladesh, the main fish feed ingredients for prawn farming are rice bran, maize, soya bean meal, mustard oil cake, fish meal and meat and bone meal. This study was designed to evaluate the suitability of variable concentrations of low-cost oil-extracted sunflower cake in the diet for freshwater prawn M. rosenbergii in freshwater gher aquaculture system of Southern Bangladesh.

Effects of supplementary feeds with different protein levels on growth and economic performances of Nile tilapia (Oreochromis niloticus) cultured in a rain-fed rice-fish ecosystem

This study investigated the effects of supplementary feeds with different crude protein levels on the growth and economic performances of sex-reversed Nile tilapia (Oreochromis niloticus) reared in a rain-fed rice-fish ecosystem for a period of 120 days at Kushtia Sadar Sub District in Bangladesh

Mycoflora and mycotoxins in finished fish feed and feed ingredients from smallholder farms in East Africa

In this article, the authors provide a pioneer snapshot of the co-occurrence of aflatoxins, fumonisin and ochratoxin A, as well as other mycotoxins, in fish feed and ingredients from East Africa. A total of 52 samples of finished fish feeds and ingredients were collected from smallholder farmers in Kenya, Tanzania, Rwanda and Uganda, and analyzed.

Myanmar Fisheries and Aquaculture Research Symposium Proceedings

The Myanmar Fisheries and Aquaculture Research Symposium was held in Yangon on 16-17 November 2017. The event provided a unique opportunity for national and international researchers to take stock of present sectoral knowledge and jointly identify the most promising pathways for impactful fisheries and aquaculture research in Myanmar. The event was cooperatively organized by WorldFish and the Department of Fisheries (DoF) under the umbrella of the Fisheries Research Development Network (FRDN).

Effects of soybean meal and high-protein sunflower meal on growth performance, feed utilization, gut health and gene expression in Arctic charr (Salvelinus alpinus) at the grow-out stage

The objectives of this study were to investigate the effects of graded levels of solvent-extracted soybean meal and further-processed high-protein sunflower meal on growth, nutrient utilization, intestinal health and pro-inflammatory mRNA expression in Arctic charr at the grow-out stage.

Improving feed efficiency in fish using selective breeding: A review

Improving feed efficiency (FE) is key to reducing production costs in aquaculture and to achieving sustainability for the aquaculture industry. Feed costs account for 30-70% of total production costs in aquaculture; much work has been done on nutritional and husbandry approaches to improve FE but only a limited amount of research has been devoted to using genetics, despite its potential. This paper reviews past work to improve FE in fish using selective breeding and assess future directions.

Measuring individual feed efficiency and its correlations with performance traits in Nile tilapia, Oreochromis niloticus

Estimating individual feed intake of fish held in groups has long been a challenge precluding precise knowledge of the individual variation of feed efficiency (FE) in fish. In this study, counts of the number of feed pellets (1.63 mg on average) eaten by individual tilapia (Oreochromis niloticus) held in 8 mixed sex groups of 15 fish were measured from video recordings made over a period of 10 days where fish were fed twice daily to achieve compensatory growth after 10 days of fasting.

Evaluation of different aquaculture feed Ingredients in Indonesia using Life Cycle Assessment

Indonesia’s aquaculture industry has grown by almost 25% annually over the last five years, an achievement enabled through the increased use of commercial aquaculture feeds, made from agricultural, capture fisheries and livestock resources. The reliance of aquaculture on capture fisheries has, however, attracted criticism, as has the land use consequences of imported Brazilian soybeans. Sourcing more sustainable resources has thus become part of maintaining a good environmental image and to secure long-term growth.
