Iowa State Co•servcttion(•ommissio,•, Des Moit•cs, Iowa .•BSTRACT The stmnaeh contents of 912 channel catfish (769 containing food) taken iu a short section of the Des Moines River from September, 1940, to October, 1911, are analyzed. The physical and biotic elmraeteristies of the study area are described; a partial list of the fishes present together xvith comments on their importance and relative abundance is included. The ehanuet eatfish is omnivorous, as is revealed by a review of the pertinent literature and by this study. A wide wtriety of organisms is eaten (some 50 families of insects alone are represented--these are listed). Insects and fish serve as staple foods, plant seeds are taken i• season, and various other items are eaten in limited numbers. The principal groups of foods (insects, fish, plants, and miscellaneous) are anMyzed volumetrically, by œrequeney of occurrence, and numerically. In the area studied, catfish grow at a rate of about 4 inches a year during the first 3 years of life (determined by length-frequency analysis). These natural size groups are utilized to establish the relationship between size and food habits. Young fish feed ahnost exclusively on aquatic insect larvae--chiefly midges, blackflies, mayflies, and enddis flies. In fish frmn 4 to 12 inches lo•g insects continue to make up the bulk of the food, but at progressively greater size larger insects (mayflies and caddis flies) are eaten with increasing frequency and dipterans are of less importonce than in the smaller size group; snmll fish and plant seeds become significant items of diet. -
Invasive Catfish Management Strategy August 2020
Invasive Catfish Management Strategy August 2020 A team from the Virginia Department of Game and Inland Fisheries uses electrofishing to monitor invasive blue catfish in the James River in 2011. (Photo by Matt Rath/Chesapeake Bay Program) I. Introduction This management strategy portrays the outcomes of an interactive workshop (2020 Invasive Catfish Workshop) held by the Invasive Catfish Workgroup at the Virginia Commonwealth University (VCU) Rice Rivers Center in Charles City, Virginia on January 29-30, 2020. The workshop convened a diverse group of stakeholders to share the current scientific understanding and priority issues associated with invasive catfishes in Chesapeake Bay. The perspectives shared and insights gained from the workshop were used to develop practical, synergistic recommendations that will improve management and mitigate impacts of these species across jurisdictions within the watershed. Blue catfish (Ictalurus furcatus) and flathead catfish (Pylodictis olivaris) are native to the Ohio, Missouri, Mississippi, and Rio Grande river basins, and were introduced into the Virginia tributaries of Chesapeake Bay in the 1960s and 1970s to establish a recreational fishery. These non-native species have since spread, inhabiting nearly all major tributaries of the Bay watershed. Rapid range expansion and population growth, particularly of blue catfish, have led to increasing concerns about impacts on the ecology of the Chesapeake Bay ecosystem. 1 Chesapeake Bay Management Strategy Invasive Catfish Blue and flathead catfishes are long-lived species that can negatively impact native species in Chesapeake Bay through predation and resource competition. Blue catfish are generalist feeders that prey on a wide variety of species that are locally abundant, including those of economic importance and conservation concern, such as blue crabs, alosines, Atlantic menhaden, American eels, and bay anchovy. -
Molecular Systematics of Gadid Fishes: Implications for the Biogeographic Origins of Pacific Species
Color profile: Disabled Composite Default screen 19 Molecular systematics of gadid fishes: implications for the biogeographic origins of Pacific species Steven M. Carr, David S. Kivlichan, Pierre Pepin, and Dorothy C. Crutcher Abstract: Phylogenetic relationships among 14 species of gadid fishes were investigated with portions of two mitochondrial DNA (mtDNA) genes, a 401 base pair (bp) segment of the cytochrome b gene, and a 495 bp segment of the cytochrome oxidase I gene. The molecular data indicate that the three species of gadids endemic to the Pacific Basin represent simultaneous invasions by separate phylogenetic lineages. The Alaskan or walleye pollock (Theragra chalcogramma) is about as closely related to the Atlantic cod (Gadus morhua) as is the Pacific cod (Gadus macrocephalus), which suggests that T. chalcogramma and G. macrocephalus represent separate invasions of the Pacific Basin. The Pacific tomcod (Microgadus proximus) is more closely related to the Barents Sea navaga (Eleginus navaga) than to the congeneric Atlantic tomcod (Microgadus tomcod), which suggests that the Pacific species is derived from the Eleginus lineage and that Eleginus should be synonymized with Microgadus. Molecular divergences between each of the three endemic Pacific species and their respective closest relatives are similar and consistent with contemporaneous speciation events following the reopening of the Bering Strait ca. 3.0–3.5 million years BP. In contrast, the Greenland cod (Gadus ogac) and the Pacific cod have essentially identical mtDNA sequences; differences between them are less than those found within G. morhua. The Greenland cod appears to represent a contemporary northward and eastward range extension of the Pacific cod, and should be synonymized with it as G. -

Does Climate Change Bolster the Case for Fishery Reform in Asia? Christopher Costello∗
Does Climate Change Bolster the Case for Fishery Reform in Asia? Christopher Costello∗ I examine the estimated economic, ecological, and food security effects of future fishery management reform in Asia. Without climate change, most Asian fisheries stand to gain substantially from reforms. Optimizing fishery management could increase catch by 24% and profit by 34% over business- as-usual management. These benefits arise from fishing some stocks more conservatively and others more aggressively. Although climate change is expected to reduce carrying capacity in 55% of Asian fisheries, I find that under climate change large benefits from fishery management reform are maintained, though these benefits are heterogeneous. The case for reform remains strong for both catch and profit, though these numbers are slightly lower than in the no-climate change case. These results suggest that, to maximize economic output and food security, Asian fisheries will benefit substantially from the transition to catch shares or other economically rational fishery management institutions, despite the looming effects of climate change. Keywords: Asia, climate change, fisheries, rights-based management JEL codes: Q22, Q28 I. Introduction Global fisheries have diverged sharply over recent decades. High governance, wealthy economies have largely adopted output controls or various forms of catch shares, which has helped fisheries in these economies overcome inefficiencies arising from overfishing (Worm et al. 2009) and capital stuffing (Homans and Wilen 1997), and allowed them to turn the corner toward sustainability (Costello, Gaines, and Lynham 2008) and profitability (Costello et al. 2016). But the world’s largest fishing region, Asia, has instead largely pursued open access and input controls, achieving less long-run fishery management success (World Bank 2017). -
Clean &Unclean Meats
Clean & Unclean Meats God expects all who desire to have a relationship with Him to live holy lives (Exodus 19:6; 1 Peter 1:15). The Bible says following God’s instructions regarding the meat we eat is one aspect of living a holy life (Leviticus 11:44-47). Modern research indicates that there are health benets to eating only the meat of animals approved by God and avoiding those He labels as unclean. Here is a summation of the clean (acceptable to eat) and unclean (not acceptable to eat) animals found in Leviticus 11 and Deuteronomy 14. For further explanation, see the LifeHopeandTruth.com article “Clean and Unclean Animals.” BIRDS CLEAN (Eggs of these birds are also clean) Chicken Prairie chicken Dove Ptarmigan Duck Quail Goose Sage grouse (sagehen) Grouse Sparrow (and all other Guinea fowl songbirds; but not those of Partridge the corvid family) Peafowl (peacock) Swan (the KJV translation of “swan” is a mistranslation) Pheasant Teal Pigeon Turkey BIRDS UNCLEAN Leviticus 11:13-19 (Eggs of these birds are also unclean) All birds of prey Cormorant (raptors) including: Crane Buzzard Crow (and all Condor other corvids) Eagle Cuckoo Ostrich Falcon Egret Parrot Kite Flamingo Pelican Hawk Glede Penguin Osprey Grosbeak Plover Owl Gull Raven Vulture Heron Roadrunner Lapwing Stork Other birds including: Loon Swallow Albatross Magpie Swi Bat Martin Water hen Bittern Ossifrage Woodpecker ANIMALS CLEAN Leviticus 11:3; Deuteronomy 14:4-6 (Milk from these animals is also clean) Addax Hart Antelope Hartebeest Beef (meat of domestic cattle) Hirola chews -

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -
