High Coral Thermal Tolerance At A Potentially Climate-Resistant Reef, Kate M. Quigley, C. Siqueira, Kira Brereton, Andrew H. Baird Jan 2026

High Coral Thermal Tolerance At A Potentially Climate-Resistant Reef, Kate M. Quigley, C. Siqueira, Kira Brereton, Andrew H. Baird

Research outputs 2022 to 2026

Ecosystems globally are under increasing pressure from warming caused by climate change. However, some locations appear resistant to impacts. Although rare, these locations might be able to better resist damage from thermal stress. In marine environments, coral bleaching is widely viewed as one of the most pervasive stress responses threatening reef health, structure, and function. Yet we still have a poor understanding of the drivers of spatial and temporal variation in the scale and severity of coral bleaching. Here, we characterize a prolonged, intense, and widespread marine heatwave event and uncover a conspicuous lack of bleaching at the southernmost coral …


Stocking Density Effects On Growth Performance Of Glass Eels (Anguilla Bicolor Pacifica) In Outdoor Tank Conditions, Frolan A. Aya Dec 2025

Stocking Density Effects On Growth Performance Of Glass Eels (Anguilla Bicolor Pacifica) In Outdoor Tank Conditions, Frolan A. Aya

The Philippine Agricultural Scientist

Optimizing stocking density is necessary to maximize the production efficiency of farmed fish. This study examined the effect of stocking density on the growth performance of the Pacific shortfin eel Anguilla bicolor pacifica reared in outdoor tank conditions. Glass eels (0.72 ± 0.03 g mean body weight [BW]) were stocked at 50 and 100 individuals m−2 in 6 4-m2 outdoor tanks with a flow-through system set up in triplicate. Eels were individually measured for total length and BW, followed by blood sampling at the end of the 286-d trial. Glass eels stocked at a density of 50 m …


The Benefits Of High Phosphate Concentration (10n : 1p) And Diagonal Orientation On The Ex Situ Grow-Out Of Caribbean Coral Juveniles, Ashley Shen Aug 2025

The Benefits Of High Phosphate Concentration (10n : 1p) And Diagonal Orientation On The Ex Situ Grow-Out Of Caribbean Coral Juveniles, Ashley Shen

All HCAS Student Capstones, Theses, and Dissertations

As coral reefs keep declining, it is imperative to increase coral production ex situ for restoration, but this requires culture protocols to be optimized. This study examined the impacts of grow-out orientation and phosphate concentration (and nitrate (N): phosphate (P) ratio) on the survival and growth of Montastraea cavernosa and Pseudodiploria clivosa juveniles from 3 to 9 months old. Pristine reefs typically have low nitrate (0.12μmol/L) and low phosphate (0.03μmol/L) concentrations, leading to N:P ratios of 4-16 N: 1P. In recirculating tanks, it is difficult to lower nitrate concentrations below 25μmol/L. Here we hypothesized that increasing the phosphate concentration in …


Investigating Nekton Response To Changing Salinities In The Mississippi Sound: An Experimental And Statistical Approach, Adam Murray Dec 2024

Investigating Nekton Response To Changing Salinities In The Mississippi Sound: An Experimental And Statistical Approach, Adam Murray

Master's Theses

The Mississippi Sound provides nursery habitats for many coastal species and is recognized for its commercial fisheries. Previous freshening events linked to the Bonnet Carré Spillway, a Mississippi River flood diversion structure, proved catastrophic for oyster populations in the Mississippi Sound, but effects on mobile fish and shellfish species are not well-defined. The planned Mid-Breton Sediment Diversion (MBSD), an initiative to combat wetland loss, is also forecasted to lower salinities in the region, increasing the need to better understand responses of commercially and ecologically important species to freshening events. The objective of this study was to characterize effects of salinity …


The Effects Of Simulated Predation And Nursery Structure On Post-Outplant Survival And Growth Of Sexual Juveniles Of Six Caribbean Coral Species, Jarrod Little Aug 2024

The Effects Of Simulated Predation And Nursery Structure On Post-Outplant Survival And Growth Of Sexual Juveniles Of Six Caribbean Coral Species, Jarrod Little

All HCAS Student Capstones, Theses, and Dissertations

Over the past few decades, increasing frequency and severity of direct and indirect anthropogenic stressors have resulted in reef degradation and decreased coral cover and diversity. In South Florida, coral propagation ex situ has gained popularity as a means to restore coral cover. Outplanting sexually propagated corals on the reef is particularly important as it contributes to greater genetic diversity and potentially overall reef resilience. However, these corals typically experience high levels of predation following outplanting, significantly reducing coral survival, and thus constitute a major bottleneck to the success of restoration efforts. This study assessed if simulated predation events on …

Reproduction, Early Development, And Larval Rearing Of The Climbing Perch Anabas Testudineus (Teleostei: Anabantidae) In Captivity, Frolan A. Aya, Reylan C. Gutierrez, Luis Maria B. Garcia Jun 2023

Reproduction, Early Development, And Larval Rearing Of The Climbing Perch Anabas Testudineus (Teleostei: Anabantidae) In Captivity, Frolan A. Aya, Reylan C. Gutierrez, Luis Maria B. Garcia

The Philippine Agricultural Scientist

Induced spawning, early development, and larval rearing of the climbing perch Anabas testudineus were examined under captive conditions. Five female climbing perch [125.33 ± 3.27 mm SL; 70.67 ± 5.59 g BW] were paired with apparently mature males (108.50 ± 3.97 mm SL; 39.27 ± 4.70 g BW) and induced to spawn with 5,000 IU human chorionic gonadotropin (hCG) + 0.5 mL Ovaprim kg BW-1. All hCG + Ovaprim-injected fish spawned 9 – 11 h after hormone administration but saline-injected fish (control group) failed to spawn. Mean egg production per female, fertilization and hatching rates, and larval production …
