Sustainable Fishmeal Alternatives: Impact Of Partially Defatted Black Soldier Fly (Hermetia Illucens) Meal On Growth And Health Of Yellowtail Kingfish (Seriola Lalandi), Luke Pilmer, Lindsey Woolley, Alan J. Lymbery, Michael Salini, Chinh Dam, Md Javed Foysal, Gavin Partridge

Fisheries Research Articles

Reducing fishmeal (FM) in aquaculture diets is essential for improving sustainability and reducing reliance on marine resources. Black soldier fly (BSF; Hermetia illucens) larvae meal is a promising alternative protein source. This study evaluated the effects of replacing FM with BSF meal on the growth and health of juvenile yellowtail kingfish (YTK) (Seriola lalandi, initial weight ~22 g). Fish were reared in 24 tanks (three replicates per treatment) and fed for 33 days under controlled conditions. Eight diets were tested: a control (40% FM) and seven diets with BSF meal replacing FM at 25%, 50%, or 75%, …

Is Anoxia Tolerance A Common Trait In Fish Cell Lines?, Lori Tran

University Honors Theses

Most vertebrates need a constant supply of oxygen to sustain life, with disruption to O₂ supply or delivery quickly leading to cell and tissue damage and death. Many aquatic species are able to withstand long periods without O₂ due to evolving to survive the regular periods of hypoxia and anoxia in their natural habitat. The Austrofundulus limnaeus, or the annual killifish, in particular have shown the highest anoxia tolerance in all vertebrates and is a promising model for developing effective treatments for anoxia-related damage, such as heart attacks and strokes. The A. limnaeus are not the only …

Growth And Survival Of Silver Therapon (Leiopotherapon Plumbeus [Kner, 1864]) Larvae Fed With Artemia Franciscana Enriched With Isolated Endogenous Probiotic Bacteria, John Carlo Unido, Precious Dee Tolentino, Christian Paul Dela Cruz, Carmela Jhoy Dy, Honey Grace Samonte

The Philippine Agricultural Scientist

This study aimed to isolate, characterize, and identify endogenous lactic acid bacteria (LAB) from the gut of silver therapon (Leiopotherapon plumbeus) and to evaluate their potential as probiotics by enriching live food organisms, specifically brine shrimp (Artemia franciscana), and feeding them to L. plumbeus larvae. Three unknown bacterial isolates were screened and characterized as catalase-negative, Gram-positive, rod-shaped bacteria that showed tolerance to pH and bile, growth at temperatures of 30 and 40 °C, and inhibitory activity against pathogenic bacteria in vitro. The selected isolate was then confirmed as Lactobacillus sp. through partial sequencing of its 16S …

In December 2022, the Minister for Fisheries announced commercial and recreational (including charter) sector …

Ecospiritual Entanglement, Ali Vedad Yüner

Masters Theses

Land breeds culture. It gives us the resources to thrive, and in that process we establish a relationship with its constituents. With a multitude of beings inhabiting the land, a complex web of relationships develop. Biology describes these relationships as food webs; the mass entanglement of organisms in a manner that each organism nourishes the other. These webs are not just mere scientific structures but rather an interpretation of existential connections that every organism in the world, humans included, are indebted to. Food webs are the first stepping stone in the formation of culture, as they account for the engagement …

Temporal Assessment Of Fish Communities In A South Central Plains Ecoregion Watershed, Tara L. Schnelting

ATU Theses and Dissertations 2021 - Present

Among South Central Plains ecoregion fish communities, there is limited knowledge of the importance of headwaters yet this information is needed to understand their role in fish communities. I addressed this gap by assessing seasonal changes in fish communities in headwater streams of the Moro Creek watershed, Arkansas. I conducted two studies pertaining to temporal fish community assessments: (i) utilize multi-season, community occupancy models to estimate μ (species probability), Ω (community occupancy mean), and p (detection probability) and (ii) utilize beta diversity (β) analyses to address the diversity across different scales in the headwaters of the Moro Creek …

The introduction of non-native fish species in the freshwater ecosystems of the Philippines presents a clear threat to native ichthyofauna, making verified reports of such introductions all the more critical. Through the examination of a collected specimen and anecdotes from fisherfolk and social media, we present here the first records of the occurrence of the tinfoil barb, Barbonymus schwanefeldii (Bleeker, 1854), in Laguna de Bay, Luzon Island, Philippines. This represents the addition of another non-native fish species in this lake, which is increasingly becoming dominated by non-native and invasive fishes that have been intentionally or accidentally introduced. Monitoring landed fish …

Design And Optimization Of Aquaculture Gear: Development Of A Cage-Integrated Reeling Mechanism For Oyster Farming, Felicity Bryant

Honors Theses

This project encompasses the design, fabrication, and testing of a cage-integrated reeling system aimed at reducing the physical labor required in oyster aquaculture at Bama Bay Oyster Farm, the last operational oyster farm in Mobile Bay. The proposed system includes two primary components: lightweight, modular oyster cages and a dual-winch reeling device for automated retrieval. Three cage prototypes—rectangular, oval, and hexagonal—were evaluated for structural performance and fabrication feasibility. The oval design was ultimately excluded due to practical fabrication limitations. The rectangular and hexagonal designs were fabricated using recycled materials and tested under the most extreme environmental conditions derived from years …

Assessment Of Sampling Gears For Bigheaded Carp In Mid-Order Prairie Rivers In Nebraska, Brett M. Anderson

School of Natural Resources: Dissertations, Theses, and Student Research

Silver Carp Hypophthalmichthys molitrix and Bighead Carp H. nobilis (collectively bigheaded carp) have invaded tributaries to the Missouri River and Platte River in Nebraska, USA. Information pertaining to efficient sampling protocols for assessing bigheaded carp populations as well as benefiting removal efforts is needed. Herding is a method used to increase the capture efficiency and detection probability of adult bigheaded carp by simultaneously using active and passive sampling gears. During June-July 2023, four herding techniques were assessed regarding their ability to elicit directional movement past an enclosure gate. The combination of sound and electrofishing resulted in the highest mean …

Morphology Of Smallmouth Bass (Micropterus Dolomieu) In Arkansas, Robert Laroche

Biological Sciences Undergraduate Honors Theses

The Smallmouth Bass, Micropterus dolomieu, is one of the most important game fishes in Arkansas. Three distinct lineages are recognized from different river basins: the Northern, Neosho, and Ouachita Smallmouth Bass. Understanding the biodiversity within this species complex inhabiting different water bodies in Arkansas is important for effective management of the fisheries resource and to guide conservation efforts. But current data on distribution of distinct forms are insufficient to guide management. The primary goals of the study presented here was to quantify morphological characteristics to identify distinct lineages of Smallmouth Bass, and to determine their specific locations within Arkansas streams …

Walleye And Sauger Movement And Entrainment In Lewis And Clark Lake, William Joseph Radigan

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Walleye Sander vitreus and Sauger Sander canadensis are both socioeconomically important sportfish species in Lewis and Clark Lake, an interjurisdictionally managed mainstem Missouri River reservoir fishery. Since 2011, adult catch per unit effort (CPUE) of both Walleye and Sauger has remained at approximately 50% of pre-2011 levels. A presumed reason for the suppressed CPUE of adult Walleye and Sauger is substantial entrainment of larval and adult fish resulting from the reservoir’s high turnover rate (7.2 d). Acoustic telemetry was used to quantify adult movement and entrainment and ichthyoplankton trawls were used to assess larval entrainment. Relative importance of factors driving …

Can Assessment Of Morphometrics Correctly Predict Species In Madtoms?, Harley C. Walden

ATU Scholars Symposium

Species delineation is commonly achieved through genetic analyses, but the utility of morphometrics as an alternative method remains unclear. This study investigates whether morphometric measurements can effectively differentiate species in madtoms (Noturus spp.). A total of 10 morphometric traits were measured from 50 individuals each of three madtom species: the Slender Madtom (Noturus exilis), the Black River Madtom (Noturus maydeni), the Ozark Madtom (Noturus albater), the Ouachita Madtom (Noturus lachneri) and the Freckled Madtom (Noturus nocturnus). Random forest modeling was employed to identify which morphometric variables most accurately distinguish between …

Distribution Of Mussels In Two Intermittent Upland Streams Of The Arkansas Valley Ecoregion, Aaron A. Brady, Seth Drake, Zach Crain, Kendall Moles

ATU Scholars Symposium

Freshwater mussels are facing an increasing need for conservation due to their declining populations. More data is needed on mussel distributions, especially in tributaries of large rivers to properly conserve and restore populations. Big Shoal Creek and Little Shoal Creek are two upland-tributaries of the Arkansas River (Lake Dardanelle) in which no records exist for freshwater mussel populations. We addressed this knowledge gap by sampling a total of 9 sites in Little Shoal Creek and 18 sites in Big Shoal Creek to determine the abundance and distribution of mussels in these streams. Mussels were sampled using a timed search approach. …

Fisheries Management Paper No.286: Western Australian Octopus Resource Harvest Strategy, Department Of Primary Industries And Regional Development, Western Australia
