A preliminary assessment of the shallow water prawn stocks off Mocambique, North of Beira [PDF]
, 1980 At present, the trawl fishery for shallow water prawns is the only industrialized national fishery in Mozambique. Most of the catch is exported. Plans are laid for expansion of the fishery, and this report is an attempt to make a preliminary assessment ...

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.ABSTRACT Cetaceans are indicators of ocean health, influence marine ecosystem dynamics and hold socio‐economic importance for coastal whaling communities. Yet whale–whaler relationships remain poorly understood and are increasingly compromised under the triple planetary crisis of climate change, biodiversity loss and pollution. Here, we briefly outline

NAMMCO Scientific Publications, 2002 Three ice entrapments of Monodontids have been reported in the western North Atlantic since 1993. Hunters in Disko Bay, West Greenland, discovered one in March 1994 that included about 150 narwhals (Monodon monoceros).

Aspartic acid racemization rate in narwhal (Monodon monoceros) eye lens nuclei estimated by counting of growth layers in tusks [PDF]
Polar Research, 2012 Ages of marine mammals have traditionally been estimated by counting dentinal growth layers in teeth. However, this method is difficult to use on narwhals (Monodon monoceros) because of their special tooth structures.

Prawn seed resources and its farming potentialities in Sunkeri back waters (Kali Estuary - Karwar) [PDF]
, 1982 Prawn seed resources of Sunkeri back waters indicated the availability of Penaeus indicus, P. monodon, Metapenaeus dobsoni and M. monoceros. The monthly variation in seed composition, its correlation with environmental parameters and the aquaculture ...

The Anatomical Record, Volume 309, Issue 2, Page 397-416, February 2026.Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.

A review of age estimation methods in marine mammals with special reference to monodontids
NAMMCO Scientific Publications, 2018 This paper presents a critical review of methods for estimating absolute or relative age in marine mammals. Absolute age is achieved by counting growth layer groups (GLGs) in hard structures such as teeth, ear plugs, baleen, bones and claws. Relative age

Seed requirements for intensive culture of penaeid prawns in coastal waters, particularly in Kerala [PDF]
, 1980 The extent of estuaries and brackish waters in Kerala is estimated at about 0.243 million ha. Of this, 1,21,600 ha could be utilised for penaeid prawn culture.

Predators and scavengers: Polar bears as marine carrion providers
Oikos, Volume 2026, Issue 1, January 2026.Scavenging is a foraging strategy widely used across the animal kingdom and apex predators provide a large amount of energy in a food web by provisioning carrion. In the harsh environmental conditions of the Arctic, apex predators such as polar bears Ursus maritimus can provide scavenging opportunities for many species. Carrion can act as a buffer when
