Comparative study of skipjack tuna Katsuwonus pelamis (Scombridae) fishery stocks from the South Atlantic and western Indian oceans

Scientia Marina, 2019
The skipjack tuna, Katsuwonus pelamis, inhabits tropical and subtropical oceans the world over, and contributes substantially to total tuna catches. Both fishing pressure and anthropic influences affect skipjack populations, impacting on economic returns

Environmental and Protection Effects of Shark‐Companion Associations Across Three Ocean Basins

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Companion species frequently associate with large marine hosts, yet the ecological drivers of these relationships remain poorly understood. Using a global dataset of midwater BRUVS deployments, we modelled the presence and abundance of shark‐companion associations across seven shark species and three ocean basins.

Saturation Attacks on Reduced Round Skipjack [PDF]

, 2002
This paper describes saturation attacks on reduced-round versions of Skipjack. To begin with, we will show how to construct a 16-round distinguisher which distinguishes 16 rounds of Skipjack from a random permutation. The distinguisher is used to attack on 18(5~22) and 23(5~27) rounds of Skipjack. We can also construct a 20-round distinguisher based on

The Occurrence of Microplastic Ingestion in Commercial Marine Fish in Miri, Sarawak, Malaysia

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Microplastics are polymer‐based particle compositions of various toxic chemicals with size less than 5 mm. Due to their small size, microplastics can be ingested and accumulate in body tissues of organisms. This raises concerns about their toxicity being transferred to humans via food consumption.

Detection of pelagic habitat hotspots for skipjack tuna in the Gulf of Bone-Flores Sea, southwestern Coral Triangle tuna, Indonesia.

PLoS ONE, 2017
Using remote sensing of sea surface temperature (SST), sea surface height anomaly (SSHA) and chlorophyll-a (Chl-a) together with catch data, we investigated the detection and persistence of important pelagic habitat hotspots for skipjack tuna in the Gulf

Biological Base of Skipjack as The Foundation for Sustainable Fisheries Management in The Flores Sea [PDF]

BIO Web of Conferences
Skipjack fishing in the Flores Sea using pole and line is conducted in FAD and non-FAD. Fishing in FAD areas is expected to optimize fishing activities without considering the level of utilization and sustainability of fish resources.

Active Versus Passive eDNA Sampling Across Depths at a Tropical Fish‐Aggregating Device (FAD)

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Sampling at a fish aggregating device over three consecutive days using active and passive samplers detected a total of 39 fish operational taxonomic units (OTUs). Of these, 25 OTUs were shared between the two sampling approaches. The composition of detected OTUs varied among days and between sampler types.

Distribution and abundance of skipjack (Katsuwonus pelamis) larvae in eastern Brazilian waters

Brazilian Journal of Oceanography, 1982
Based on data from two ichthyoplankton surveys carried out off the eastern Brazilian coast in June and November-December 1978, the larval distribution of skipjack is discussed.

Morphology and Distribution of Olfactory Receptor Neurons in Southern Bluefin Tuna, Thunnus maccoyii (Teleostei): Implications for Olfactory Hydrodynamics

Journal of Morphology, Volume 287, Issue 5, May 2026.
The number and distribution of olfactory receptors over the olfactory lamellar surface of four juvenile southern bluefin tuna were quantified using scanning electron microscopy. The microvillous olfactory receptors (mORN) are concentrated in the rostral region of the lamellar surface, while ciliated olfactory receptors (cORN), which are dominant in ...
