“…Setting catch levels low enough to protect species connected by predator-prey relationships helps to conserve biodiversity and prevent the phenomenon of ‘fishing down marine food webs’, whereby depletion of predator species results in increasing numbers of smaller low-trophic level fishes in catches (Pauly et al 2002 ). Use of artificial fishing baits, as alternatives to the use of fishes for bait (Dellinger et al 2016 ; Karunanithi et al 2018 ; Masilan & Neethiselvan 2018 ), might enable fewer such fishes to be caught, benefiting conservation and welfare.…”

Finfishes are caught from the wild for food, feed (often in the form of fishmeal and oil) and bait. According to the Food and Agriculture Organisation of the United Nations (FAO), between 74 and 83 million tonnes (averaging 77 million tonnes) were caught annually in 2000–2019. Although fishes are now widely recognised as sentient beings, capture is still quantified as biomass rather than number of individuals (in contrast to wild-caught marine mammals and crocodiles; and farmed mammals and birds). Here, we estimate global numbers of wild-caught finfishes using FAO capture production (landing) tonnages (2000–2019 data) and estimates of mean individual weight at capture, based on internet-sourced capture and market weights. We estimate that between 1,100 and 2,200 billion (1.1–2.2 × 1012), or 1.1–2.2 trillion, wild finfishes were caught annually, on average, during 2000–2019. Anchoveta (Engraulis ringens) comprised 28%, by estimate midpoint. Estimated numbers in 2019, totalling 980–1,900 billion, were lower due to reduced anchoveta landings, but still represented 87.5% of vertebrate numbers killed for food or feed, as obtained or estimated from FAO data. These figures exclude unrecorded capture such as illegal fishing, discards and ghost fishing. Estimated finfish numbers used for reduction to fishmeal and oil represented 56% of the total 2010 estimate (1,000–1,900 billion), by midpoint. It is recommended that the FAO reports fish capture numbers. The welfare of wild-caught fishes, which is generally very poor during and after capture, should be addressed as part of sustainable utilisation of aquatic resources.

“…However, limited information is available on the utilization of fish processing wastes for the development of fish bait. In recent times, attentions have been paid to develop biodegradable artificial fish baits from fish processing wastes (Siikavuopio et al, 2017;Karunanithi et al, 2018aKarunanithi et al, , 2018b. Production of fish gelatin is considered as one of the ways of utilizing processing discards from the seafood industry (Gomez-Guillen et al, 2002;Muyonga, Cole & Duodu, 2004a, 2004bBadii & Howell, 2006;Muralidharan et al, 2013;Jeyashakila et al, 2012aJeyashakila et al, , 2012bNagarajan et al, 2012aNagarajan et al, , 2012bNagarajan et al, , 2014Elavarasan et al, 2016;Govindaswamy et al, 2018;Renuka et al, 2019).…”

“…Gelatin has also been used for artificial fish bait development (Masilan & Neethiselvan, 2018). Attempts have been made throughout the world for developing artificial fish baits using different kinds of biopolymers like gelatin, chitosan, carrageenan and other binding materials (Chanes-Miranda & Viana, 2000;Dellinger et al, 2016;Løkkeborg et al, 2014;Karunanithi et al, 2018a;Ollis et al, 2004;Siikavuopio et al, 2017). UNO has stressed the need for developing artificial fish baits with the view to conserve forage fishes which are exploited to the tune of 18 MMT globally every year (UNO, 2014) to use in long line fishing as baits, of which around 40% are found to be vital species with good food value and ideal for direct human consumption (Dellinger et al, 2016).…”

Extraction of gelatin from fish wastes and the development of artificial fish bait matrix using the extracted gelatin were attempted in the study. Biochemical composition of fish wastes (heads, skins, fins and scales) and the gelatin derived from the wastes of corresponding body parts and physicochemical properties of fish gelatin were analyzed. Considering high yield (19.8–22.4%), good gel strength (1.99–2.3 N), high melting point (27 °C) and simple extraction process, the scale gelatin was selected for the development of artificial fish bait matrix. To optimize the levels of gelling agent, cross linker and solvent for the preparation of bait matrix, RSM was adopted. Gel strength and insolubility ratio were analyzed to know the suitability of the bait. They were found to have the gel strength ranging from 1.3 N to 23.5 N, insolubility ratio from 55–83%, and melting point from 34.3 °C to 41.1 °C. The optimum levels of ingredients for the preparation of ideal bait matrix were standardized as: gelatin-25.5%, sucrose-22.5% and water-52%. The curing temperature and curing duration were optimized based on the optimum gel strength of 20.84 N and insolubility ratio of 74.5% was 5 °C and 25 h respectively. The study revealed that a developed fish bait matrix suitable for fishing can be made from gelatin derived from fish wastes.
