Jointness through fishing days input in a multi-species Fishery [PDF]

open access: yes
Some multi-species fisheries are characterised by production jointness in the sense that several species are caught through a joint production process (literally in the same haul of the net). Other multi-species fisheries (so called purse seine fisheries)

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

An investigation of factors related to the bycatch of small cetaceans in fishing gear

open access: yes, 2011
The bycatch of cetaceans in fishing gear is considered to be one of the biggest conservation threats to these species. Gear modifications have the potential to reduce these bycatches in global fisheries but there is little available information on how ...

Fasting and Refeeding Mediated Phospholipid Remodeling Plays an Important Role in Improving Meat Quality of Aged Laying Hens

open access: yesAnimal Research and One Health, EarlyView.
ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Effects of fishing during the spawning period: implications for management

open access: yes, 2010
Avoidance of fishing during the spawning season has been proposed as a contribution to achieving sustainable exploitation. Here we review the biological effects of fishing during the spawning period and explore their implication on sustainable management.

Catch abundance and fishing season from vulnerable and endangered Elasmobranch species in Tanjung Luar Fishery

open access: yes, 2019
The elevated extinction risk of elasmobranchs is proportional with the increase of fishing mortality due to overfishing. Indonesia is the biggest shark fishing country in the world, with Tanjung Luar as a fishing village specifically targeting sharks ...

Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis

open access: yesAnimal Research and One Health, EarlyView.
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...

Sustainable levulinic acid production from inulin via hydrothermal conversion

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study investigates the hydrothermal conversion of inulin using potassium pyrosulfate to levulinic acid (LA). The Box–Behnken design approach was applied to optimize the conversion parameters and analyze the interactions influencing LA yield.
