“…The presence of anti-nutritional factors in the diet could hinder the digestive enzyme activity (Liu et al, 2018). The low fishmeal diet with no supplementation (SPC 1) resulted in reduced amylase and protease activity.…”

An eight-week growth trial and a four-week digestibility trial was undertaken to assess the impact of DL-methionine and phytase supplementation on growth performances, apparent digestibility coefficients (ADC), phosphorus retention and digestive enzyme activities of Penaeus vannamei. Five treatment groups in three replicates fed with a control diet (fishmeal 200 g/kg), and four low fishmeal (50 g/kg) diets with soy protein concentrate-soybean meal protein viz., SPC1 (without supplementation), SPC 2 (DL-methionine), SPC 3 (Phytase) and SPC4 (DL-methionine and phytase). SPC 2 had significantly improved (p < .05) the weight gain (5.79 ± 0.12), FCR (1.53 ± 0.06) and SGR (3.21 ± 0.06) than other low fishmeal diets, but not significantly different to that of SPC 4 and control. SPC 2 also showed significantly higher protease activity. P retention was significantly higher in SPC 2 than SPC 1, SPC 3 and control, however, not significantly different from SPC 4. Faecal phosphorus load was significantly reduced in SPC 2 than SPC 1 and control. Protein digestibility was significantly higher in SPC 2 and SPC 4, whilst phosphorus digestibility was significantly higher in SPC 4. Thus, it is concluded that the supplementation of DL-methionine is essential for the overall better performances of P. vannamei in low fishmeal diets and phytase for improving phosphorus digestibility.

“…Additionally, digestive tracts of distinct species of fish vary considerably in their structure and pH. Aforementioned factors could explain differences in effects from phytic acid on nutrient digestibility in different studies, including experiments investigating effects from supplemented phytic acid 135,139,140,150–155 . Furthermore, phytic acid could lower the activity of digestive enzymes like trypsin, 150,152,156 however, increased activity of other endopeptidases could compensate for this effect 150 .…”

“…Phytic acid has been demonstrated to decrease feed intake in different species of fish, when it was supplemented to diets (2.1% [Atlantic salmon], 2.8% [rainbow trout], 0.5% [grass carp, Ctenopharyngodon idella V., 1844], 1.6% [grass carp] of diet) 150–152,155 . Results showed a significant decrease in feed intake at different phytic acid concentrations, which could be due to species‐specific taste preferences 243,244 ; however, there is no tangible explanation available on the exact mechanisms involved.…”

The aquaculture sector has been the key factor in meeting the growing demand for high-quality food by contributing significantly to the global fish production. The portion of fishmeal in aqua feeds has been decreased significantly in recent years, however, increased production in aquaculture still led to demands of fishmeal that cannot be covered by sustainably caught small pelagic fish. Hence, alternatives for fishmeal in aqua feeds are an inevitable necessity. Different plant proteins have been evaluated in the past and rapeseed proteins are considered valuable protein sources for fishmeal-free aqua feeds. Rapeseed is highly available on a global scale and provides one of the most balanced amino acid composition among plant-based protein sources. Additionally, rapeseed cultivation is characterised by low production costs, ecological and economic benefits in cerealdominated agriculture and provision of two highly nutritive products. Subsequently, rapeseed proteins have been intensely investigated over the past decades and knowledge of the application of these proteins in diets for different species of fish has improved dramatically. However, there is no adequate complete review for the application of rapeseed proteins in aqua feeds. This review outlines and discusses the relevant factors influencing the inclusion of rapeseed proteins as fishmeal alternatives in fish diets and highlights provisional thresholds for anti-nutritive substances as well as future research needs.

“…Natural feed additives proved to be efficient, reducing the need for medicated treatments, decrease metabolic waste production and improve fillet quality (Gonçalves and Santos, 2017). Pre-and probiotics became routinely used as well as special feed additives like exogenous enzymes HANCZ ACTA AGRARIA KAPOSVÁRIENSIS 2020(24)1 37 (Hardy, 2000;Cerezuela et al, 2011;Kazerani and Shahsavani, 2011;Ganguly et al, 2013;Carnevali et al, 2017) or phytic acid (Liu et al, 2017). Application of phytochemicals that can affect fish health, growth and feed utilization is also spreading as extensive use of antibiotics has encouraged the evolution of resistant bacteria (Chakraborty and Hancz, 2011;Chakraborty et al, 2013).…”

Ameliorating of feed efficiency always was and will remain the key element of aquaculture in which minimalizing losses during feed intake play an important role. Decreasing feed losses important not only from the economic point of view but also from an environmental standpoint. Feeding stimulants are often used additives in complete aquaculture feeds. Better knowledge of the food-sensing of cultured species is essential in the development of adequate feeding stimulants. The present paper aims to overview the nutrient-sensing of aquatic animals and the use of the wide variety of feeding attractants and stimulants.
