The Philippine Agricultural Scientist

There is a growing interest in the aquaculture of tropical anguillid eels as an export commodity. However, studies on feeding strategies, and the present demand to reduce feed costs need to be addressed to ensure the economic viability of eel farming. In this study, the effects of daily (DF) and alternate day (ADF) feeding on growth, feed utilization, body composition, blood chemistry, liver and intestinal morphology, and economic viability in the Pacific shortfin eel Anguilla bicolor pacifica were examined. Each feeding group of 30 elvers (166.25 ± 16.23 g mean initial wt) were randomly stocked in triplicate 4 m^{3 …}

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 …

Grow-Out Culture Of Oyster Magallana Bilineata (Röding, 1798) Using Pouches: A Comparison Of Growth And Survival In The River And Earthen Pond, Ma. Junemie Hazel L. Lebata-Ramos, Ellen Flor D. Solis, Mark Jude C. Almeida

The Philippine Agricultural Scientist

Oysters are among the most in-demand aquaculture commodities in the Philippines and worldwide. With the decreasing culture area and the deteriorating water quality of oyster beds, there is a need to explore new culture sites and techniques to address the problems of dwindling stocks and the increasing demand for better quality oysters. This study compared the growth and survival of the oysters Magallana bilineata, the new accepted name of Crassostrea iredalei, cultured in an earthen pond and the river using pouches suspended from rafts. Mean growth rates of oysters in length and weight were significantly higher in those …

A Preliminary Assessment Of The Spawning Potential Ratio Of Five Target Species Of The Coastal Gillnet Fishery In Guyana And Suriname, Tomas Willems, Elford Liverpool, Michael Hiwat

Gulf and Caribbean Research

Data—limited stock assessment methods have the potential to positively impact livelihoods of fishermen around the world by providing management recommendations that aim to optimize sustainable yields from fisheries. Some years ago, a novel length— based (LB) method was developed for the assessment of spawning potential ratio (SPR), a measure of the reproductive capacity of fish stocks. We applied the LB—SPR method to 5 important target species of the coastal gillnet fishery in Guyana and Suriname. Nebris microps (Smalleye Croaker; 32% SPR) and Macrodon ancylodon (King Weakfish; 34% SPR) had the highest spawning potential, but remained below the 40% target level …

Life History Of Swordfish, Xiphias Gladius, Caught In The Northern Gulf Of Mexico, Anna K. Millender, Jeremy M. Higgs, Nancy J. Brown-Peterson, Michael J. Andres, James S. Franks

Gulf and Caribbean Research

The current study examined 93 Swordfish, Xiphias gladius, (64 females, 27 males, 2 unknown) ranging in size from 77.6–246.3 cm lower jaw fork length (LJFL) from the northern Gulf of Mexico (GOM). Samples were collected between March and August in 2005–2007, 2017–2019 and 2021. Age estimates of 51 Swordfish resulted in a maximum observed age of 11 years (205.0 cm LJFL) and 7 years (190.4 cm LJFL) for females and males, respectively. Observed and back—calculated length—at—age data were fitted to 4 growth models (2— and 3— parameter von Bertalanffy, Gompertz, and logistic). The 2—parameter von Bertalanffy was the model …

Atlantic Sailfish (Istiophorus Albicans) Distribution Off The East Coast Of Florida From 2003 To 2018 In Response To Sea Surface Temperature, Meredith M. Pratt

Mako: NSU Undergraduate Student Journal

The Atlantic sailfish (Istiophorus albicans) ranges from 40°N to 40°S in the Western Atlantic Ocean and has great economic and recreational value for sport fishers. Off the east coast of Florida, recreational fishing boats often target this species due to its size, speed and strength. This project aimed to determine the relationship between sea surface temperature (SST) and the distribution of Atlantic sailfish caught and released over a fifteen-year period (2003 to 2018). Tagging information was collected from The Billfish Foundation and NOAA who have the most extensive programs for billfish. Using the time and location of each …

First Records For Spawning Of Caribbean Acropora Species In Colombian Mpas, David M. Hudson, Barrett L. Christie, Luis A. Gómez-Lemos, Camilo Valcarcel, Diego Duque, Juan C. Zárate Arévalo, Jaime Rojas, Otto Reyes, Milena Marrugo, Maria Rosa, Israel A. Caicedo Torrado, Diana Tarazona, Carlos Zuluaga

Gulf and Caribbean Research

Estimates of Colombian Caribbean coral percent cover in the Southern Caribbean are consistent with those throughout the Caribbean Sea, which has declined to about 10% of historical levels in the last few decades. Human activities like destructive fishing techniques in the marine parks have degraded the reefs over the last few decades. Colombia’s Marine Protected Areas (MPAs) have thousands of square kilometers to map and patrol and few resources to devote to scientific and restoration efforts. Efforts to implement sexual reproduction techniques for restoration are starting to successfully propagate and settle corals on ceramic plates for reef deployment in the …

Short-Term Estimate Of Finfish Bycatch Discards In The Inshore Artisanal Shrimp Fishery Of Guyana, Leanna Kalicharan, Hazel A. Oxenford

Gulf and Caribbean Research

The artisanal shrimp fishery in Guyana is important for livelihood and food security, involving around 300 vessels owned and crewed exclusively by Guyanese nationals. This fishery uses Chinese seines and operates in major river estuaries. It targets penaeid shrimp, but also retains some finfish and is known to discard a significant but undocumented quantity of smaller finfish bycatch. The lack of knowledge regarding the bycatch is a concern for fishery management and biodiversity conservation. In this study, we quantify for the first time the finfish bycatch discards through onboard observations (July—August 2016) of a single typical vessel operating in the …

The Purr Of The Lionfish: Sound And Behavioral Context Of Wild Lionfish In The Greater Caribbean, Michelle T. Schärer-Umpierre, Carlos Zayas, Richard S. Appeldoorn, Evan Tuohy, Jack C. Olson, Jessica A. Keller, Alejandro Acosta

Gulf and Caribbean Research

Passive acoustic technology has become a useful and cost-effective method to collect data with very high temporal resolution that can be used to detect the presence, distribution, and remotely monitor soniferous marine biodiversity. In order to maximize the potential of bioacoustic and soundscape research in the oceans, understanding the association between the different realms of sound sources, species-specific calls and behavioral context of sound production are fundamental. A previously unknown vocalization was associated with a behavioral display of lionfish (Pterois spp.) by recordings with synchronous audio and video at deep coral reefs in both Puerto Rico and the Florida …

Exigence

Abstract

The basis of this proposal is to understand the relationship between select UV filters and coral bleaching and provide a framework for additional research. Coral reefs are home to a diversity of marine life and are keystones to major coastal economies around the world. Oxybenzone and butylparaben are major ingredients found in sunscreen that induces coral bleaching to major coral reefs. To alleviate the negative effects, this proposal will attempt to better understand how oxybenzone and butylparaben facilitates coral bleaching and develop an effective and environmentally fair sunscreen. The research proposed will be funded by donors to cover research, …

Description Of A New Sound Produced By Nassau Grouper At Spawning Aggregation Sites, Timothy J. Rowell, Michelle T. Schärer, Richard S. Appeldoorn

Gulf and Caribbean Research

This study identified a new sound produced by Nassau Grouper in association with, although potentially not exclusive to, an agonistic interaction at a spawning aggregation. We have also provided a behavioral and acoustic description for identification of this sound in future studies. The discovery of a third type of sound produced by Nassau Grouper further highlights the importance of acoustic communication coupled with visual displays in fishes. Furthermore, identification of a new sound increases the ability to document the presence of this endangered species at spawning sites. Future efforts may reveal that the sound is produced within additional behavioral contexts …
