Bankia neztalia was found in temperate waters around New Zealand, mainly south of New Plymouth and Tauranga. Bankia australis was found in warm‐temperate waters north of Nelson; it requires water temperatures above 19–20°c for successful breeding and is euryhaline. Lyrodus pedicellatus also occurred in warm‐temperate waters north of Nelson and had a lower water temperature limit for survival of about 10 °c. Lyrodus medilobatus occurred in warm‐temperate waters on the north‐east coast of the North Island north of Tauranga. Nototeredo edax is uncommon and occurred over the same range as B. australis. The presence of shipworms in wood collected from depths of greater than 50 m around New Zealand is reported. Teredora princesae is recorded from driftwood around New Zealand. 相似文献

A spawning site of Galaxias brevipinnis Giinther was located in a New Zealand stream for the first time. It was at the edge of a riffle and only partially submerged. The habitat used for spawning matched that described for G. brevipinnis in Australia. Spawning was estimated to have occurred between late April and early May and the eggs hatched in late May. The species of fish spawning was identified by rearing the eggs through to identifiable juveniles and by DNA sequencing of one individual. 相似文献

Mesoproboloid.es excavata n. sp. is described and illustrated from material collected at Kaikoura, New Zealand. It differs most conspicuously from the other three known species of the genus in the posterodistally excavate coxa 4, the stout, blunt lobe distally on article 1 of antenna 1, the crenulate ventral margins of coxae 2–4, and the castellate posterior margin of article 2 of pereopod 5. The structure and distribution of minute organs, probably sensory receptors, densely distributed over much, of the integument was examined by scanning electron microscopy. The genus Mesoproboloides is now seen to be cold temperate‐subantarctic in occurrence. 相似文献

Samples of particulate matter were analysed for nitrogen by the micro‐Kjeldahl technique in an attempt to obtain an indication of the food available for mussels. The small amounts of nitrogen available in the samples prevented the detection of seasonal variation by this method. The mean concentration of 11.8 μg‐at of nitrogen per litre obtained from this study compares favourably with data from mussel farming areas in Spain. 相似文献

The whale‐louse Scutocyamus antipodensis n.sp., ectoparasitic on Hector's dolphin, Cephalorhynchus hectori (van Beneden), is described and figured from material collected in Cloudy Bay, Cook Strait, New Zealand. Morphologically the new species is very close to S. parvus Lincoln & Hurley, the type and only other species of the genus, known only from the North Sea. However, the two species differ in the detailed structure and spinosity of the body and pereopods. 相似文献

Growth of the red gurnard, Chelidonichthys kumu (Lesson and Garnot), from Pegasus Bay, Canterbury, was measured during 1966–67. Otoliths were used as an indicator of fish growth; mean length‐at‐age data were obtained from back‐calculated fish lengths at the time of formation of successive annual rings in the otoliths. Growth in length was found to be adequately expressed by the von Bertalanffy growth equation : lt = 52.0 [1 ‐ e‐0.406 (t‐o.291)] (where lt is the fork length in cm at age t). The length: weight relationship was: w = 78.56 × 10‐4 l 3.072 (where w is the weight in grams). From this relationship, growth in weight was described by the equation: wt = 1469 [1 ‐ e‐0.406 (t‐0.291)]3. 相似文献

An unidentified species of the genus Moina was found in a Pasveer sewage treatment plant at Glensiide, Wellington; it is described and illustrated. A survey of the literature shows that this is probably the first published record of the genus in New Zealand (M. lemnae, previously recorded, has since been tentatively referred to the genus Pseudomoina); sewage ponds in India and South Africa have yielded M. dubia. 相似文献

This paper is the fifth in a series revising the taxonomy of New Zealand dictyoceratid sponges (phylum Porifera, subclass Ceractinomorpha, order Dictyoceratida). Six new species of the genus Spongia are added to New Zealand's known fauna. The use of subgenera within the genus Spongia is discussed, and two new subgenera are proposed. The genus Hippospongia is revised, and an emended generic diagnosis is proposed. 相似文献

Drifting mysids were sampled to determine diel activity, and whether mysid numbers vary with respect to inflowing and outflowing tides. Samples of drifting mysids were collected at the mouth of the Taieri River, New Zealand, over one 24‐h cycle using five replicate conical drift nets in January 1999. One‐night and 1‐day ebb and flood tide were each sampled. Four species of mysid Tenagomysis macropsis, T. novae‐zealandiae, T. robusta, and an apparently undescribed species of Gastrosaccus sp., were collected over the sampling period. One species, T. robusta, has not previously been collected from estuarine or riverine systems. The undescribed Gastrosaccus sp. was the most abundant of the four species. All four species were more abundant at night, with T. robusta and Gastrosaccus sp. being considerably more abundant in the drift on outflowing tides. In contrast, roughly equal numbers of T. macropsis and T. novae‐zealandiae were observed drifting in and out of the estuary at night. 相似文献

Diel feeding periodicity of torrentfish (Cheimarrichthys fosteri) in two braided rivers of Canterbury,New Zealand 总被引:1,自引:1,他引:0
Torrentfish Cheimarrichthys fosteri Haast were collected at 4‐hour intervals over a full day in winter and summer, 1984–85, from the Ashley and Rakaia Rivers in Canterbury, New Zealand, to determine their diel feeding periodicity. Both populations fed, almost exclusively, from dusk to dawn in both seasons, with the quantity of food in their stomachs accumulating to peak levels by early morning. However, Ashley females had significantly less food in their stomachs than did males in summer, the season with a high incidence (91%) of females in spawning condition. Aquatic stages of Deleatidium spp. (Ephemeroptera: Leptophle‐biidae) and Chironomidae constituted from 85 to 98% by number and 63 to 80% by dry weight of all foods eaten. Chironomids (small prey) comprised up to 85% of the total foods eaten by number but only 17% by dry weight, while Deleatidium (large prey) comprised up to 69% of the prey by number and 63% by dry weight. Numerically, chironomids were an important component in the torrentfish diet in both seasons in the Rakaia (71 to 75%), but only so in winter in the Ashley (85%). The reported daily feeding cycle is consistent with observations in a simulated stream, that torrentfish largely remain inactive during the day and come out to feed at night. 相似文献

Xantharus Andronov, 1981 is reported, for the first time from New Zealand, from the upper slope (306 m) off the southeastern coast of North Island (41°04.10′S, 176°22.05′E). Xantharus cryeri n. sp. females differ from the three known species by a combination of characters: antennules that extend to the distal border of pedigerous somite 2; ancestral segment XVIII of the antennule with 1 seta; mandible basis with 3 setae; maxilla endite 1 with 5 setae; leg 1 basis with inner distal border lined with small spinules; and leg 5 is squat, with all segments as long as wide and the 2 terminal spine‐like extensions of the terminal segment approximately as long as the articulated, inner, subterminal spine. 相似文献

This taxon is distinguished from other Ergasilidae by having only three pairs of legs, and a well‐developed hook on the penultimate joint of the second antenna abutting against the claw‐like terminal segment. A. amplexus has been reported from Anguilla australis, A. dieffenbachii, Perca fluviatilis, Carassius auratus, Retropinna retropinna, Physiculus bachus, Galaxias maculatus, Arripis trutta, Rhombosolea leporina, R. retiaria, and R. plebeia from Lake Ellesmere, near Christchurch, and from Anguilla australis from Makara River near Wellington. Both localities are euryhaline. 相似文献
