“…A tremendous increase in fish consumption endorses high biological protein value and a superior source of omega‐3 fatty acids. Rohu ( Labeo rohita ) is a common freshwater fish in Pakistan with high consumer preference thus ranking 10th in terms of aquaculture species (Baset, 2020; Mehar et al, 2022). An estimated figure of around 18 to 30 million tons of waste with no financial value was recorded annually from the fish processing industry (Mukkanti & Tembhurkar, 2021).…”

This study aimed to develop nano‐sized‐biogenic hydroxyapatite (HAp) from fishbone; followed by calcination at 850°C. The core part of the research “ultra‐sonication” was done following different levels of operating variables. Characterization of resulted HAp was done using different techniques. FTIR spectra confirmed PO43− peak at 1031.77 cm−1. As per the findings of atomic absorption spectroscopy (AAS) and particle size distribution (PSD), 128.04 ± 0.19 ppm calcium and 50–400 nm particle size were determined. Scanning transmission electron microscopy (STEM) confirmed agglomerated crystal lattice, whereas in XRD 2θ crystalline behavior was noted at 300 a.u. Laser‐induced breakdown spectroscopy (LIBS) derived Ca/P‐Ratio was 1.69. HAp was further used to develop nano‐sized‐biogenic HAp fortified refined wheat flour tortillas with four formulations at 0%, 0.2%, 0.4%, and 0.6% levels. Tortilla was characterized for moisture (%) and spread ratio lied within 6.20 ± 0.05 to 8.15 ± 0.83 and 5.95 ± 0.08 to 5.80 ± 0.03, respectively. Best average acceptance was seen in a formulation named NBio‐FB1 (0.2) which could thus prove a better choice for end‐users regarding the potential to eradicate calcium deficiency. Moreover, PCA underlined 74.82% total variance. Novelty impact statement The ultrasonic processing method was practiced to reduce the particle size of HAp obtained from the discarded fish bone. With Ca/P ratio of nano‐sized‐biogenic HAp was determined by LIBS. Moreover, fortification of tortillas with nano‐sized‐biogenic HAp powders developed from fishbone may play a role to improve bone health.

In the aquaculture feed industry, fishmeal is widely used as a source of animal protein due to its high palatability, excellent amino acid profile and increased digestibility.However, the incorporation of fishmeal in aquaculture diets increases the costs of production due to the declining wild fish stocks hence an urgent need to search for sustainable and cheaper alternative protein sources. The use of fermented plant proteins as substitutes for fishmeal in aquaculture diets has recently gained attention due to their improved nutritional quality, easy availability and low costs. Therefore, a systematic review and meta-analysis were conducted to quantify the effects of fermented plant proteins as substitutes for fishmeal on the growth performance, feed utilisation, survival, antioxidant, metabolic and digestive enzyme activity of several aquaculture species. Results of the meta-analysis indicated that replacement of fishmeal with fermented plant proteins in aquaculture diets enhanced the growth performance, feed utilisation, antioxidant and digestive enzyme activities of several aquaculture species regardless of experimental duration and source of fermented plant protein. Likewise, metabolic enzyme activity (i.e., Alanine aminotransferase and Aspartate aminotransferase) was reduced in experimental dietary treatment groups relative to the fishmeal control groups. To elucidate the influence of moderators on the observed effect sizes, a mixed-effects model was conducted and the results indicated that fishmeal substitution levels and aquaculture species influenced the observed effect sizes in both antioxidant and digestive enzyme activity. No significant differences were noted in survival between the experimental dietary treatment groups and fishmeal control diets among all aquaculture species. However, carnivorous marine species exhibited lower values for specific growth rate and protein efficiency ratio in experimental dietary treatment groups compared to the fishmeal control diets. Likewise, freshwater species exhibited poor FCR values in experimental dietary treatment groups relative to the fishmeal control diets. Overall, the replacement of fishmeal with fermented plant proteins in aquaculture diets is a safe and viable solution for increased and sustainable aquaculture production.

“…In some instances, secondary traits are assessed routinely, along with traits under direct selection, to monitor changes in breeding populations over time and/or validate predicted correlated responses (Garber et al 2019;Lhorente et al 2019;Verbyla et al 2021). The status of secondary traits can change over time with changes in the understanding of markets and trait preferences (Mehar et al 2021), environments (e.g. climate change) (Lhorente et al 2019), disease introductions/outbreaks (Barría et al 2020), management systems (e.g.…”

Genetic correlations between harvest weight and secondary traits in a silver carp (Hypophthalmichthys molitrix) genetic improvement program

et al. 2022

In 2017, the base population of a family-based silver carp (Hypophthalmichthys molitrix) genetic improvement program was spawned in Bangladesh. This program aims to improve the growth rate of silver carp under polyculture production systems, through direct selection on the primary trait of harvest-age weight. The objective of this study was to quantify genetic variation in, and genetic correlations between, harvest-age weight (assessed on 8012 fish from 184 families) and a set of secondary traits (assessed on 1603 fish from 175 families). Secondary traits examined included feeding and digestive system traits (i.e. gill raker sponginess and gut length as a ratio of standard length), a morphometric trait (i.e. extent of overlap of pectoral and pelvic fins) and health traits (i.e. presence of Lernaea and prevalence of red spots — sites of inflammation/haemorrhaging). Despite not being under direct selection, genetic change in secondary traits is possible across generations in closed genetic improvement populations as a result of a correlated response to selection for the primary trait (i.e. indirect selection), adaptation to culture conditions, inbreeding and/or genetic drift. It was found that the additive genetic variance within genetic groups was significantly different from zero for all but the studied health traits. Heritability estimates for harvest-age weight and pectoral/pelvic fin overlap were moderate (0.24 and 0.22, respectively) but were low for gill raker score and relative gut length (0.12 and 0.09, respectively). Genetic correlations between harvest-age weight and secondary traits were not significantly different from zero, indicating that selection for harvest-age weight will not result in a correlated response to selection in the studied secondary traits.
