Irondequoit Bay Fish Stock Assessments 2005-2015, Matthew J. Sanderson

Technical Reports

Warm water fisheries assessments using standard gangs of gill nets were conducted in Irondequoit Bay in September of 2005, 2010, and 2015. In addition, a nighttime electrofishing survey was conducted in June 2009. The surveys were conducted to 1) assess the fish community; 2) determine the contribution of stocked fingerlings to the walleye (Sander vitreus) population; 3) estimate population characteristics of walleye, northern pike (Esox lucius), yellow perch (Perca flavescens), and largemouth bass (Micropterus salmoides), 4) compare fish community structure to statewide surveys; and 5) guide the development of appropriate management recommendations. From 2005 to 2015 overall gill net catch ...


Changes In Zooplankton Community, And Seston And Zooplankton Fatty Acid Profiles At The Freshwater/Saltwater Interface Of The Chowan River, North Carolina, Deborah A. Lichti, Jacques Rinchard, David G. Kimmel Aug 2017

Changes In Zooplankton Community, And Seston And Zooplankton Fatty Acid Profiles At The Freshwater/Saltwater Interface Of The Chowan River, North Carolina, Deborah A. Lichti, Jacques Rinchard, David G. Kimmel

Environmental Science and Ecology Faculty Publications

The variability in zooplankton fatty acid composition may be an indicator of larval fish habitat quality as fatty acids are linked to fish larval growth and survival. We sampled an anadromous fish nursery, the Chowan River, during spring of 2013 in order to determine how the seston fatty acid composition varied in comparison with the zooplankton community composition and fatty acid composition during the period of anadromous larval fish residency. The seston fatty acid profiles showed no distinct pattern in relation to sampling time or location. The mesozooplankton community composition varied spatially and the fatty acid profiles were typical of ...


Fatty Acid Profiles Of Major Prey And Predator Fish In Lake Ontario: Use In Assessing Food Web Interactions, Robert G. Pattridge Iii Feb 2016

Fatty Acid Profiles Of Major Prey And Predator Fish In Lake Ontario: Use In Assessing Food Web Interactions, Robert G. Pattridge Iii

Environmental Science and Ecology Theses

Fatty acid signatures (FAS) are currently used in food web studies to assess trophic interactions between predator and prey. In this study, three major prey fish (alewife, rainbow smelt, and round goby) were collected at three sites along the south shore of Lake Ontario (Olcott, Rochester, and Oswego) during the spring and fall of 2013. Major predator species (including lake trout, brown trout, Chinook salmon, coho salmon, chain pickerel, northern pike, yellow perch, and walleye) were collected along the south shore of Lake Ontario during the summer of 2013. Using multivariate statistics, FAS were compared among all predator and prey ...


Aspects Of Bowfin And Northern Sunfish Biology And Ecology, David Sanderson-Kilchenstein Dec 2015

Aspects Of Bowfin And Northern Sunfish Biology And Ecology, David Sanderson-Kilchenstein

Environmental Science and Ecology Theses

Bowfin (Amia calva) are currently being harvested at high rates in the Mississippi River system for the sale of their roe as a caviar alternative. I evaluated the effect that this industry could have if it expands to include the Great Lakes by describing population characteristics of bowfin from Braddock Bay, Monroe Co., NY. Pectoral fin ray sections were used to age 51 bowfin, and back-calculated length-at-age data were used to fit the Von Bertalanffy growth model. Theoretical maximum length was estimated to be 753 mm TL, the coefficient of growth 0.262, and time at length zero -0.023 ...


Conesus Lake Fish Stock Assessments 2001-2009, Matthew J. Sanderson Oct 2014

Conesus Lake Fish Stock Assessments 2001-2009, Matthew J. Sanderson

Government Documents

Warm water fisheries assessments using standard gangs of gill nets were conducted in Conesus Lake in September of 2001, 2004, and 2009. The purpose of the surveys was to assess the fish community; the contribution of stocked fingerlings to the walleye (Sander vitreus) population; estimate population characteristics of walleye, smallmouth bass (Micropterus dolomieui), and northern pike (Esox lucius); compare fish community structure to previous surveys; and guide the development of appropriate management recommendations. From the 1990’s to the 2000’s, species dominance shifted from walleye to sunfish (Lepomis, sp.), and yellow perch (Perca flavescens) went from being a major ...


Minnow Diversity And Habitat Associations In The West Branch Of Sandy Creek, Orleans County, New York, Coral Lenore Reina Apr 2014

Minnow Diversity And Habitat Associations In The West Branch Of Sandy Creek, Orleans County, New York, Coral Lenore Reina

Environmental Science and Ecology Theses

While often attempted, successfully associating fish species with in-stream and riparian land use habitat variables has been problematic in fisheries literature. To explore such associations in the west branch of Sandy Creek, Orleans County, New York, I sampled 12 in-stream variables in rifle, run and pool habitats, three land use variables along urban, agricultural and forested stream segments, as well as the fish communities associated with the nine in-stream habitat and land use combinations. Cluster analysis yielded cluster grouping patterns and determined which habitat variables and fishes influenced clustering of land uses and in-stream habitats. Creek chub (Semotilus atromaculatus), river ...


Lipid And Fatty Acid Differences In Lake Trout (Salvelinus Namaycush) Eggs From The Great Lakes, Cayuga Lake, And Lake Champlain, Robert Carl Louis Geroux Oct 2013

Lipid And Fatty Acid Differences In Lake Trout (Salvelinus Namaycush) Eggs From The Great Lakes, Cayuga Lake, And Lake Champlain, Robert Carl Louis Geroux

Environmental Science and Ecology Theses

The main objectives of this study were to determine and compare fatty acid signatures (FAS) of lake trout eggs within and among the Great Lakes region. Fifteen sites were sampled over 2 years, including six sites in Lake Michigan, four sites in Lake Huron and one site each in Lake Ontario, Lake Superior, Lake Champlain, and Cayuga Lake. A total of 518 egg samples were quantified. A combination of univariate and multivariate statistical analyses was used to assess spatial and temporal differences in FAS in both the neutral lipid (NL) and phospholipid (PL) fractions of lake trout eggs. At each ...


Dietary Effects Of Non-Native Species On Yellow Perch, Perca Flavescens, Reproductive Performance, Christina Ann Cappelli Dec 2012

Dietary Effects Of Non-Native Species On Yellow Perch, Perca Flavescens, Reproductive Performance, Christina Ann Cappelli

Environmental Science and Ecology Theses

In Lake Michigan, native yellow perch (Perca flavescens) have experienced poor recruitment since 1989. With the introduction of non-native species yellow perch prey fish have changed dramatically, which could affect successful recruitment of these fish. Therefore, in the present study I investigated dietary effects of two non-native species (alewife and round goby) on female yellow perch reproduction using lipid and fatty acid composition of their eggs, liver, muscle, and visceral fat. Two-year-old yellow perch were fed two diets, representing two distinct fatty acid signatures. These two diets were significantly different, in terms of fatty acid composition, with alewife containing higher ...


The Effect Of Highly Unsaturated Fatty Acids (Hufa) On Lake Trout (Salve Linus Namaycush) Alevins Using Artemia Nauplii Enriched With Commercial Emulsions And Dry Diets, Blake J. Snyder Oct 2011

The Effect Of Highly Unsaturated Fatty Acids (Hufa) On Lake Trout (Salve Linus Namaycush) Alevins Using Artemia Nauplii Enriched With Commercial Emulsions And Dry Diets, Blake J. Snyder

Environmental Science and Ecology Theses

Highly unsaturated fatty acids (HUFA) are important nutrients for fish survival, development, and reproduction. Fish oil (PO), rich in HUFA, is the dominant lipid source for first feeds in salmonid aquaculture. To determine if other lipid sources would influence survival, growth, and fatty acid profiles in lake trout (Salvelinus narnaycush) alevins, two 8-week feeding experiments were performed. Diets used in the Artemia Experiment included: diet 1, non-enriched Artemia; diet 2,SELCO-enriched Artemia; diet 3, Super SELCO-enriched Artemia; and diet 4, Bio Vita #0, all of which had significantly different fatty acid compositions. The Fish Oil Replacement Experiment used diets that ...

Effects Of Vitamin B1 (Thiamine) Deficiency In Lake Trout (Salvelinus Namaycush) Alevins And Preventive Treatments, Bong-Joo Lee, Marta Jaroszewska, Konrad Dabrowski, Sergiusz Czesny, Jacques Rinchard

Environmental Science and Ecology Faculty Publications

The objectives of this study were to examine the effect of thiamine immersion of fish from a population known for compromised survival as a result of early mortality syndrome (EMS) and to investigate the cause–response relationship between thiamine concentration and lesions in tissues in swim-up-stage lake trout Salvelinus namaycush alevins. Lake trout eggs from 14 fish from Lake Michigan were artificially fertilized and the progeny divided into two groups based on the thiamine concentration (low [,0.73 nmol/g] or high [.0.85 nmol/g]) in the unfertilized eggs. Progeny were treated or not with a thiamine solution (2 ...

Effect Of Thiamine Status On Probability Of Lake Ontario Chinook Salmon Spawning In The Upper And Lower Sections Of Salmon River, New York, H. George Ketola, James H. Johnson, Jacques Rinchard, Francis J. Verdoliva, Mary E. Penney, Andreas W. Greulich, Russell C. Lloyd

Environmental Science and Ecology Faculty Publications

Consumption of thiaminase-containing forage fishes reduces egg and muscle thiamine content and impairs the spawning migration of Cayuga Lake (New York) rainbow trout Oncorhynchus mykiss. Because some Chinook salmon O. tshawytscha from Lake Ontario have been shown to produce eggs low in thiamine, we examined the relationship between the migration of Chinook salmon and the thiamine content of their eggs spawned in the lower and upper sections of the Salmon River, a major tributary to Lake Ontario, in 2003–2006. Eggs from the upper section of the river were collected from 79 salmon returning to the state hatchery 25 river ...


Molecular Markers Of Yolk Sac Fry Development In Nine Families Of Lake Trout, Kristiina A. Vuori, Tiia Paavilainen, Mikko Nikinmaa, Sergiusz Czesny, Jacques Rinchard Jan 2009

Molecular Markers Of Yolk Sac Fry Development In Nine Families Of Lake Trout, Kristiina A. Vuori, Tiia Paavilainen, Mikko Nikinmaa, Sergiusz Czesny, Jacques Rinchard

Environmental Science and Ecology Faculty Publications

Salmonids in certain areas of North America and northern Europe suffer from reproductive disturbances manifested through the death of yolk sac fry. These disturbances are referred to as early mortality syndrome (EMS) in the Great Lakes region and M74 in the Baltic Sea. Both of these syndromes have been associated with reduced concentrations of thiamine in affected females and their eggs. However, large variations in signs and mortality, both within and between the individual syndromes, have been reported. Yolk sac fry mortality (M74) in Atlantic salmon Salmo salar has been shown to be associated with reduced DNA binding of the ...


Linking Egg Thiamine And Fatty Acid Concentrations Of Lake Michigan Lake Trout With Early Life Stage Mortality, Sergiusz Czesny, John M. Dettmers, Jacques Rinchard, Konrad Dabrowski Jan 2009

Linking Egg Thiamine And Fatty Acid Concentrations Of Lake Michigan Lake Trout With Early Life Stage Mortality, Sergiusz Czesny, John M. Dettmers, Jacques Rinchard, Konrad Dabrowski

Environmental Science and Ecology Faculty Publications

The natural reproduction of lake trout Salvelinus namaycush in Lake Michigan is thought to be compromised by nutritional deficiency associated with inadequate levels of thiamine (vitamin B1) in their eggs. However, mortality driven by thiamine deficiency (commonly referred to as early mortality syndrome [EMS]) is not the only significant cause of low lake trout survival at early life stages. In this study, we sought to better understand the combined effects of variable levels of thiamine and fatty acids in lake trout eggs on prehatch, posthatch, and swim-up-stage mortality. We sampled the eggs of 29 lake trout females from southwestern Lake ...

The Potential Of Pigeon Creek, San Salvador, Bahamas, As A Nursery Habitat For Juvenile Coral Reef Fish, Ian C. Conboy

Environmental Science and Ecology Theses

The government of the Bahamas is considering making parts of San Salvador a National Marine Park. This study was conducted to assess the significance of Pigeon Creek, a shallow tidal lagoon, as a nursery for coral reef fishes. The perimeter of Pigeon Creek is lined with mangrove and limestone bedrock. Depending on location in the Creek, the bottom is sand or seagrass and ranges in depth from shallow intertidal sand flats to deeper, tide-scoured channels with a maximum depth of 3 m. In June 2006 and January 2007, fish were counted and their reproductive status Juvenile or adult) was recorded ...

Two experiments were carried out to evaluate the efficacy of commercial and experimental diets on the survival, growth, and body composition of juvenile yellow perch Perca flavescens. In both experiments, fish were fed by hand four to five times a day at a restricted ration of up to 90% satiation for 51 d. In experiment 1, fish (initial weight, 87 6 24 mg) were fed three experimental diets (F1, F2, and a casein–gelatin-based diet) and one commercial diet (Kyowa 400B). In experiment 2, fish (initial weight, 174 6 56 mg) were fed four experimental diets (Kyowa 400B, INVE-NRD, a ...


Intrapopulation Variation In Egg Lipid And Fatty Acid Composition And Embryo Viability In A Naturally Spawning Walleye Population From An Inland Reservoir, Sergiusz Czesny, Jacques Rinchard, Konrad Dabrowski Jan 2005

Intrapopulation Variation In Egg Lipid And Fatty Acid Composition And Embryo Viability In A Naturally Spawning Walleye Population From An Inland Reservoir, Sergiusz Czesny, Jacques Rinchard, Konrad Dabrowski

Environmental Science and Ecology Faculty Publications

The objective of the study was to evaluate the variation in embryo viability within a population of walleye Sander vitreus from an inland reservoir throughout the spawning season. Egg size, egg lipid content, and fatty acid composition were used as criteria to evaluate egg quality. Additionally, we sought to verify whether any particular size-class of females produces superiorquality eggs or whether the time of spawning (early, middle, or late) has an effect on egg quality. Seventy-seven ovulating walleye females (total length, 465–885 mm) were captured in Salt ForkReservoir, Ohio, throughout the spawning season. Although egg diameter after water hardening ...


Exposure To Perchlorate Induces The Formation Of Macrophage Aggregates In The Trunk Kidney Of Zebrafish And Mosquitofish, Tim Capps, Sandeep Mukhi, Jacques Rinchard, Chris W. Theodorakis, Vicki S. Blazer, Reynaldo Patiño Jan 2004

Exposure To Perchlorate Induces The Formation Of Macrophage Aggregates In The Trunk Kidney Of Zebrafish And Mosquitofish, Tim Capps, Sandeep Mukhi, Jacques Rinchard, Chris W. Theodorakis, Vicki S. Blazer, Reynaldo Patiño

Environmental Science and Ecology Faculty Publications

Environmental contamination of ground and surface waters by perchlorate, derived from ammonium perchlorate (AP) and other perchlorate salts, is of increasing concern. Exposure to perchlorate can impair the thyroid endocrine system, which is thought to modulate renal and immune function in vertebrates. This study with zebrafish Danio rerio and eastern mosquitofish Gambusia holbrooki examined the histological effects of perchlorate on the trunk kidney, which in teleosts serves excretory and hemopoietic functions and therefore may be a target of perchlorate effects. Adult zebrafish of both sexes were exposed in the laboratory to waterborne, AP-derived perchlorate at measured concentrations of 18 mg ...


Population Characteristics, Habitats, And Movements Of Lake Sturgeon (Acipenser Fulvescens) In The Lower Niagara River, Thomas C. Hughes May 2002

Population Characteristics, Habitats, And Movements Of Lake Sturgeon (Acipenser Fulvescens) In The Lower Niagara River, Thomas C. Hughes

Environmental Science and Ecology Theses

Before my study, anecdotal information, such as incidental catches and reported sightings, provided the only means of assessing lake sturgeon, a species listed as threatened in New York State, in the lower Niagara River. The objectives of my study were to ( 1) assess the population of lake sturgeon by collecting and analyzing age, growth, and CPUE data, (2) compare the habitats and movements of adults and juveniles, and (3) identify potential spawning, feeding, and nursery habitats and compare use of these habitats between adults and juveniles. From late July 1998 through August 2000, 67 lake sturgeon were captured using gill ...


Habitat Requirements Of Stream Spawning Walleye: An Evaluation Of Habitat Suitability Index (Hsi) Information And Lake Erie/Niagara River Tributaries, Christopher Eric Lowie Dec 1998

Habitat Requirements Of Stream Spawning Walleye: An Evaluation Of Habitat Suitability Index (Hsi) Information And Lake Erie/Niagara River Tributaries, Christopher Eric Lowie

Environmental Science and Ecology Theses

A Lake Erie Walleye Spawning Stream Rehabilitation Plan was initiated by the New York State Department of Environmental Conservation to stabilize and enhance walleye recruitment in Lake Erie. One component of the plan includes stream habitat assessment to determine candidate streams for rehabilitation efforts. Information from research literature has been compiled to develop a Habitat Suitability Index (HSI) model and identify optimum habitat requirements for walleye. The model hypothesizes species-habitat relationships which can vary by geographical area. The objectives of my thesis project were to: (1) determine habitat conditions in a local stream where walleye spawn (control site); (2) compare ...


A Review Of Lake Ontario Water Quality With Emphasis On The 1981-1982 Intensive Years, International Joint Commission Council Of Great Lakes Research Managers Oct 1988

A Review Of Lake Ontario Water Quality With Emphasis On The 1981-1982 Intensive Years, International Joint Commission Council Of Great Lakes Research Managers

Government Documents

Three issues are currently being addressed with respect to the Lake Ontario ecosystem: eutrophication, contamination by toxic substances and fisheries management. This report reviews our present knowledge and understanding of Lake Ontario within the context of the first two issues. Although the report focuses on intensive studies carried out during 1981-82, it relies heavily on work from 1967 to 1985.

I n preparing this report, it became obvious that many fundamental questions regarding the functioning of the Lake Ontario ecosystem remain unanswered. For example, although the total phosphorus load has been reduced to a level approaching the target load, those ...
