Ling and hake are tertiary consumers, and as a result both may have an important structuring role in marine communities. The diets of 2064 ling and 913 hake from Chatham Rise, New Zealand, were determined from examination of stomach contents. Ling was a benthic generalist, and hake a demersal piscivore. The diet of ling was characterised by benthic crustaceans, mainly Munida gracilis and Metanephrops challengeri, and demersal fishes, mainly Macrourids and scavenged offal from fishing vessels… 

The diet and trophic niche of orange perch, Lepidoperca aurantia (Serranidae: Anthiinae) on Chatham Rise, New Zealand

The diet of the New Zealand orange perch was determined from examination of stomach contents of 248 specimens sampled by bottom trawl on Chatham Rise, east of South Island, New Zealand, over three years, with year and time of day explaining 24% of the deviance in diet.

Diet and scavenging habits of the smooth skate Dipturus innominatus.

The diet of smooth skate Dipturus innominatus was determined from examination of stomach contents of 321 specimens sampled from research and commercial trawlers at depths of 231-789 m on Chatham Rise, New Zealand, and the best predictors of diet variability were D.innominatus length and a spatial model.

Diet of six deep-sea grenadiers (Macrouridae).

Feeding habits of six deep-sea demersal trawl-caught macrourids on Chatham Rise, New Zealand, were examined from stomach contents during the austral summer to identify the most important predictors of diet variability and included areal predictors in C. fasciatus and C. matamua.

Partial migration and early size of southern hake Merluccius australis: a journey between estuarine and oceanic habitats off Northwest Patagonia

Partial migration is a key adaptive strategy, increasingly observed across multiple taxa. To investigate partial migration and life-cycle diversity of Merluccius australis in northwestern

The trophic ecology of partial migration: insights from Merluccius australis off NW Patagonia

Partial migration, where migrant and resident organisms coexist within the same population, has been found in many fishes. Although it seems obvious that different life cycles exploit habitats and

Metabarcoding faecal samples to investigate spatiotemporal variation in the 1 diet of the endangered Westland petrel ( Procellaria westlandica ) 2

The diet of the Westland petrel is described, found that amphipods were the most common prey, followed by cephalopods and fish, and a close link between the composition of prey items and New Zealand’s commercial fishing activities is suggested.

Feeding habits of the Pacific bearded brotula Brotula clarkae Hubbs, 1944 (Ophidiidae) along the Pacific coast of Costa Rica, Central America

The diet composition, ontogenetic shifts and dietary overlap of Brotula clarkae in relation to stage of maturity and sex are analyzed, suggesting that immature B. clarkae may be subjected to high fishing pressure as by-catch, making them particularly vulnerable to overexploitation.

Investigating spatiotemporal variation in the diet of Westland Petrel through metabarcoding, a non-invasive technique

This work demonstrates how dietary DNA (dDNA) can inform the conservation of an endangered species with elusive foraging behaviour and provide valuable information regarding the diet preferences of an iconic species contributing to New Zealand’s unique biodiversity.

Variation in the diet of Genypterus blacodes(Ophidiidae) around the Falkland Islands

The diet change with size, season and area was investigated using the stomachs of kingclip Genypterus blacodes collected around the Falkland Islands between August 2001 and September 2002, and the rockcod was the most important prey.

Different food preferences in four sympatric deep-sea Macrourid fishes

Feeding habits of the four most abundant deep-sea demersal trawl-caught macrourids on Chatham Rise, New Zealand, were examined from stomach contents and cluster analyses showed that the diets of C. aspercephalus and C. bollonsi were most distinct.

Ontogenetic and spatial variation in the diet of hake (Merluccius merluccius) in the Bay of Biscay and the Celtic Sea

Analysis of the diet of trawl-caught hake from three locations in the Bay of Biscay and the Celtic Sea in autumn 2001 showed that small hake fed almost exclusively on crustaceans, but that there was a significant shift towards a fully piscivorous diet in hake 23 cm.

Feeding habits and niche separation among the deep-sea chimaeroid fishes Harriotta raleighana, Hydrolagus bemisi and Hydrolagus novaezealandiae

Generalised additive models indicated that depth was the most important spatial predictor of research trawl survey catch rates, and depth separation was most pronounced between H. raleighana and H. novaezealandiae.

Fishery and Ontogenetic Driven Changes in the Diet of the Spiny Dogfish, Squalus acanthias, in Patagonian Waters, Argentina

In the present study, carried out in 1998, squid was the most important prey, followed by the hake, related to the major decrease of hake due to overfishing and the increase of squid abundance between 1994 and 1999.

The diet of Patagonian hake Merluccius australis polylepis and its daily ration of Patagonian grenadier Macrouronus magellanicus

The diet of the Patagonian hake Merluccius australis polylepis in 1986 was determined by analysis of stomach samples collected from commercial trawl catches and the results are similar to those for other hake species in terms of composition of the diet, daily feeding cycle and daily ration.

Feeding habits of the ommastrephid squid Nototodarus sloanii on the Chatham Rise, New Zealand

The results indicated that N. sloanii, similar to other ommastrephid squids, foraged primarily in the mesopelagic layers, with crustaceans and cephalopods more important for females.

Feeding of ling Genypterus blacodes (Bloch & Schneider) from 4 New Zealand offshore fishing grounds

Stomachs contained 42 prey species from the taxa Pisces, Crustacea, Mollusca, Annelida, and Bryozoa; Macruronus novaezelandiae and Munida gregaria were the main prey species and indicated a benthic feeding mode.
