Soft plastic lures (SPLs) may comprise a significant amount of fishing gear pollution, yet little is known about their environmental impacts in aquatic systems or their ingestion by fish. We tested whether shape and material composition of ingested SPLs influenced subsequent prey consumption by Largemouth Bass Micropterus salmoides after SPL ingestion. We also quantified the occurrence of SPL ingestion by Largemouth Bass in reservoirs. Biodegradable and nonbiodegradable versions of shad, ribbon‐tail worm, and finesse worm SPLs were fed to Largemouth Bass, and consumption of natural prey was quantified 1 d and 1 week postingestion. Shape and material composition altered prey consumption by Largemouth Bass. Fish that ingested the shad SPL, the largest lure by volume, consumed the fewest number of prey 1 d postingestion. Ingestion of biodegradable SPLs resulted in lower prey consumption rates than ingestion of nonbiodegradable SPLs. Largemouth Bass typically expelled the SPL within 9 d of ingestion; all lures were either regurgitated or egested. Less than 1% of Largemouth Bass sampled in two Illinois reservoirs had SPLs in their stomachs. Our results suggest that discarded SPLs do not pose a significant long‐term threat to the health of individual Largemouth Bass. However, SPLs should still be discarded in a responsible manner.

“…In the study of Zhou and Yue (2012), evaluating the digestibility of meat and bone meal for tilapia, they found nutritional balances of dry matter and higher P and crude protein values, crude fat and gross energy lower than those found in this work for the BMs. For carnivorous species feeding habits, there is the preference for the use of animal protein, were found in the literature higher values of ADc for crude protein compared to tilapia (74.60%) for Sciaenops ocellatus (McGoogan et al, 1996), 81.8% for Lepomis macrochirus (Masagounder et al, 2009), 90% for rockfish Sebastes schlegeli (Lee, 2002) and 87.36% for Pseudoplatystoma reticulatum (Silva et al, 2013).…”

sUMMAryThis paper was aimed to determine the apparent digestibility of crude protein, crude fat, gross energy, calcium and phosphorus of tilapia meat and bone meal (Oreochromis niloticus) (TMBM), the catfish meat and bone meal (Ictalurus punctatus) (CMBM), pintado cathfish meat and bone meal (Pseudoplatystoma corruscans) (PCMBM) and the African catfish meat and bone meal (Clarias gariepinus) (ACMBM) for Nile tilapia. For that, the indirect method was used, using chromium (III) oxide (Cr 2 O 3 ), as an inert indicator incorporated in the ration of 1 g·kg -1 . Nile tilapia (400 fish) were distributed with 50±7.89 g (mean ± SD) in 20 conical tanks in a completely randomized experimental design, consisting of five treatments with four replications. The treatments consisted of a reference diet and four diets consisting of 800 g·kg-1 of reference diet and 200 g·kg-1 of the test ingredients. The PCMBM showed a better digestibility coefficients for crude protein, calcium and phosphorus, while TMBM obtained a higher value for digestible energy and crude fat. The highest mineral matter result was obtained from CMBM. The results of this study suggest that Nile tilapia has limited ability to digest and use the components in the evaluated ingredients. The presence of large amounts of structural collagen in these ingredients and their low digestibility may have caused reduction in the availability of calcium and phosphorus.Digestibilidade aparente de farinha de carne e ossos de peixe para tilápia do Nilo quimicocesar@hotmail.com resUMo Este trabalho foi realizado com o objetivo de determinar a digestibilidade aparente da proteína bruta, extrato etéreo, energia bruta, cálcio e fósforo das farinhas de carne e ossos de tilápia do Nilo (Oreochromis niloticus), do catfish (Ictalurus punctatus), do pintado (Pseudoplatystoma corruscans) e do bagre africano (Clarias gariepinus) para a tilápia do Nilo. Para tal, foi utilizado o método indireto, com o uso do óxido de cromo (III) (Cr 2 O 3 ), como indicador inerte, incorporado na ração em 1 g·kg-1. Foram distribuídas 400 tilápias com 50±7,89 g (média ± DP) em 20 tanques cônicos em um delineamento experimental inteiramente ao acaso, constituído por cinco tratamentos com quatro repetições. Os tratamentos foram compostos de uma dieta referência e outras quatro dietas constituídas de 800 g·kg-1 da dieta referência e 200 g·kg-1 da farinha de carne e ossos de tilápias, catfish, pintado e bagre africano. A farinha de carne e ossos de pintado demonstrou melhor digestão para proteína bruta, cálcio e fósforo, enquanto a farinha de carne e ossos de tilápia obteve valor maior para extrato etéreo e energia digestível. Para matéria mineral, o maior resultado obtido foi para a farinha de carne e ossos de catfish. Os resultados deste estudo sugerem que a tilápia do Nilo apresenta limitada capacidade para digerir e utilizar os componentes presentes nas farinhas de ossos avaliadas. A presença de grande quantidade de colágeno estrutural nesses ingredientes e sua baixa digestibilidade pode ter causado redu...

“…Our ADC of amino acids in blood meal were lower than those reported by Noreen and Salim (2008) for the carp Labeo rohita, which on average were 12% higher than those found in shrimp. Likewise, the amino acid ADC obtained by Masagounder et al (2009) for the bluegill Lepomis macrochirus was 25% higher. Gaylord et al (2008) evaluated the apparent digestibility of essential amino acids in a blood meal for juvenile hybrid striped bass (Morone chrysops × M. saxatilis) and obtained similar values to those found in the 2% para la harina avícola 1 y 1% para la harina avícola 2.…”

ABSTRACT. Apparent digestibility coefficients (ADC) of dry matter, crude protein (CP), and amino acids (AA) were evaluated in diets with six rendered by-products used to feed juvenile Pacific white shrimp: two poultry meals (poultry meal 1, 69% CP; poultry meal 2, 72% CP), two feather meals (89% CP), one blood meal (96% CP), and one pork meal (57% CP). Experimental diets were formulated with 30% of the test ingredient and 70% of a commercial diet supplemented with 1% of chromium oxide as inert marker. AA contents in ingredients, diets, leached diets, and feces were determined by high performance liquid chromatography. Preprandial AA losses attributed to leaching were higher in the blood meal diet (15%) and pork meal diet (10%). Poultry meal diets 1 and 2 showed mean AA losses of 3% and 5%, respectively, while the reference diet had a mean AA leaching of 6%. The AA that had the highest leaching rates were lysine (21%), methionine (15%), and histidine (12%). The ADC of dry matter was higher for poultry meals 1 (70%) and 2 (73%), followed by pork meal (69%), feather meals (61%), and blood meal (57%). The digestibility of CP was higher for poultry meals (78-80%), followed by pork meal (76%), and blood meal and feather meals (65-67%). The digestibility of CP in the reference diet (83%) was higher than that observed for all the animal by-product meals except the poultry meals. The ADC of the sum of AA adjusted for nutrient leaching fluctuated from 65% for blood meal to 80% for poultry meals.
